GENERAL INFORMATION
GENERAL SAFETY PRECAUTIONS Force measurement systems are potentially hazardous. Prior to operating your testing system, Starrett recommends that you read and understand the instruction manuals for your system and components and that you receive training on the proper use of this equipment from your authorized Starrett representative. Observe all warnings and cautions identified in this manual for your equipment. A warning identifies a function that may lead to injury or death. A caution identifies a hazard that may lead to damage to equipment or loss of data. Starrett products, to the best of our knowledge, comply with various national and international safety standards as they apply to material and force measurement testing. This Starrett product has been tested and found to comply with the following recognized standards: • EN61010-1 Safety Requirements for Electrical Equipment • EN61000-6-3 EMC Generic Emissions Standard • EN61000-6-1 EMC Generic Immunity Standard Starrett also certifies that this product complies with all relevant EU directives and carries the CE mark. WARNINGS EMERGENCY STOP SWITCH Press the emergency stop button whenever you feel there is an unsafe condition during a test. The emergency stop button removes power to the motor drive system causing the crosshead to stop. FLYING DEBRIS Eye protection, protective clothing and splinter/safety shields should be used whenever any possibility exists of a hazard from the failure of a sample, assembly or structure under test. Due to the wide range of materials that may be tested and that may result in a failure which may cause bodily injury, the precautions and preventative methods taken prior to testing is entirely the responsibility of the owner and the user of the equipment.
CRUSH HAZARD Always use caution when installing or removing apparatus and your sample material between the frame's crosshead and the base. A potential pinch/crush hazard exists. Keep clear of the testing fixture, and particularly the jaw faces at all times. Keep clear of the crosshead during movement. If available, always make sure the Pinch Load feature is enabled. This will stop inadvertent crosshead operation if in manual mode. Always ensure that other personnel cannot operate the system while you are working within the test fixture area. ELECTRICAL HAZARD Disconnect equipment from the electrical power supply before removing any electrical safety covers. Disconnect power when replacing fuses. Never reconnect power while the covers are removed. Never operate the system with protective covers removed. ROTATING MACHINERY HAZARD Always disconnect power before removing covers that protect the user from the internal rotating mechanisms. If maintenance to the drive mechanism is required, and power is needed to perform maintenance to the drive system, maintenance should be performed by an authorized Starrett representative who has received factory training on performing such procedures. LOAD SENSOR MINIMUM DEADBAND Your L1 System uses BLC Load Cell Sensors. Starrett recommends using these sensors per ASTM E4, therefore, the sensors should not be used for measurements less than 2% of the sensor's rated full scale capacity. BLC Sensors are electronic precision instruments. Starrett recommends a warm-up period of 5 minutes prior to use.

L1 SOFTWARE FOR BASIC FORCE MEASUREMENT
THIS IS A STARRETT USER GUIDE FOR THE L1 SOFTWARE FOR BASIC FORCE MEASUREMENT. ALL SPECIFICATIONS IN THIS DOCUMENT ARE CORRECT AT TIME OF PRODUCTION AND ARE SUBJECT TO CHANGE. PLEASE CONTACT STARRETT FOR FURTHER INFORMATION.
PKG08807 - UML1 7
ENGLISH
1.0 INTRODUCTION Thank you for selecting the L1 System for your force measurement testing. Your L1 System may be used for tension and compression testing including specific test methods such as peak, break, constant hold, flexural, shear, peel, coefficient of friction and more. Your L1 System should be used with Starrett equipment and accessories only. For optimum performance, your L1 System should be maintained and serviced annually by an authorized Starrett representative. 1.1 L1 SYSTEM ARCHITECTURE Your L1 System consists of the FMM Digital Testing Frame, L1 tablet with L1 software, a BLC Load Cell Sensor and test fixtures. Together, these components provide you with a full-featured testing system for most basic force measurement testing applications. 1.1.1 FMM TEST FRAMES The FMM Test Frames are available in either "Standard" or "Extended" travel formats. • Standard travel frames have a total crosshead travel of 20" (508mm) • Extended travel frames have a total crosshead travel of 30" (762mm) • FMM Test Frames are available in three capacities: 110lbf, 330lbf and 550lbf (500N, 1500N, 2500N) • FMM Test Frames have been designed exclusively for use with the L1 tablet and L1 software

ENGLISH
1.1.2 L1 TABLET AND SOFTWARE Your L1 System is supplied with a compact 2-in-1 computer with L1 software. The L1 software is licensed to the FMM Test Frame to be used with your L1 System. The computer and software use the Microsoft ® Windows ® 10 Operating System. The computer features a high-resolution touchscreen and a removable QWERTY-style keypad. The computer connects to the FMM Test Frame using the USB cable supplied with your L1 System. NOTE 1. The L1 software is licensed to one and only one FMM Test Frame. Additional licenses may be purchased from Starrett. 2. Always power ON the FMMTest Frame before powering ON the L1 tablet and software. 3. Never allow the L1 tablet to go into "Sleep Mode". This may cause a communication disconnect with the FMM Test Frame and the L1 software and which may lead to crosshead run-away condition.
1.1.3 BLC LOAD CELLS BLC Load Cell Sensors are designed exclusively for use with your L1 System. These load cells are TEDs-compliant (IEEE 1451.4) and are self- identifying once connected to your L1 System. • BLC Load Cells feature a 0.1% full scale accuracy. • BLC Load Cells mount to your FMM Test Frame using metric threads. 1.1.4 TEST FIXTURES Starrett can supply a variety of testing fixtures and grips. We can also design and manufacture custom test fixtures to your requirements. Most of the commonly-used test fixtures are clevis-type fixtures. These fixtures slide over the 15.9mm clevis and are secured using two locking rings and a grip pin. Your FMM Test Frame was supplied with a stainless steel clevis, locking rings and grip pin. 1.2 PRODUCT SUPPORT If you require product support for your Starrett system, contact your authorized Starrett representative.

2.0 L1 SYSTEM FUNDAMENTALS This section will discuss some of the basic operating fundamentals of your L1 System. 2.1 COMPUTER REQUIREMENTS L1 Systems are supplied with a portable, 2-in-1 laptop computer. The computer may be mounted to the FMM Test Frame or may be used on the workbench or desktop. The L1 software for your system has been installed and tested prior to shipment. NOTE 1. The L1 tablet should not be operated on battery power. 2. Starrett recommends the use of an uninterruptible power supply (UPS) with the L1 System, especially in locations that experience power outages and brownouts. 2.1.1 L1 TABLET OVERVIEW Your L1 tablet has our L1 software pre-installed and tested. The L1 tablet and software are optimized for touchscreen operation. The L1 tablet is supplied with a full QWERTY-style keyboard which may be removed. The L1 tablet display is 10.1 inches (1280 x 800). The L1 tablet display has the ON/OFF button on the back panel. Press to power the L1 tablet ON. Use the Windows ® OFF function to power the L1 tablet OFF. The L1 tablet display module has a Micro-USB 2.0 connector. Use the Micro-USB cable supplied with your L1 System to connect the L1 tablet to your FMM Test Frame. The FMM Test Frame USB connection is located on the back panel of the test frame. The L1 tablet's keyboard has two additional USB 2.0 connectors.
2.1.2 L1 TABLET SETTINGS Microsoft frequently updates its operating systems, in particular, driver software. Starrett recommends that the L1 tablet be setup to "Install Updates Automatically". If automatic updates are not permitted, it is the responsibility of your network administrator to ensure that the L1 tablet has the correct and most current updates for the operating system and device drivers. NOTE Starrett recommends that your L1 tablet is setup to "Install Updates Automatically" from Microsoft. The Power settings for your L1 tablet should not allow the L1 tablet to go into Sleep mode. Sleep mode interrupts communication to the FMM Test Frame and L1 software. If the L1 System is not in use, log-off the system and log-in to the system when you are ready to resume testing. CAUTION Do not use "Sleep Mode" on your L1 tablet. NOTE Use the Log-In and Log-Off procedure to correctly power On or power Off the L1 tablet and software.

2.2 L1 DISPLAY LAYOUT This section will describe the basic layout of your L1 display. 2.2.1 HEADER BAR The L1 header bar includes the following: • Main L1 Menu • Load Cell Status • Crosshead Speedometer • Test Frame Operating • Test Name • Test Type 2.2.1.1 MAIN MENU Select the Main L1 Menu target to access the L1 System Settings, to print reports or to Log-In and Log-Out of the system. 2.2.1.2 LOAD CELL STATUS The Load Cell symbol displays the full scale capacity of the BLC Load Cell that is connected to the system. The full scale value is displayed beneath the system. Select the Load Cell symbol to view the sensor's model number, serial number, last calibration date and overload history.
2.2.1.3 CROSSHEAD SPEEDOMETER The crosshead speedometer is used to control crosshead speed when in manual control. The speedometer has two speed sets: Normal and Slow. When in Normal speed, the pointer points to the right and has a green dot. Normal speed means the crosshead will obey the Motion setting. Pressing the jog key will cause the crosshead to ramp up to the maximum speed set in the Motion setting. When in Slow speed, the pointer points to the left and has a green dot. Slow speed means that when you press the jog key, the crosshead will only move at the slow speed rate for the FMM digital tester frame. This speed rate is 0.002 in/min (0.05mm/min). NOTE The Slow speed rate should be used with setting up the fixtures for your test. It is especially recommended whenever you are manually positioning the crosshead in the compression direction. 2.2.1.4 TEST FRAME MODE The FMM Test Frame only operates in Normal mode as depicted by the mode symbol.

2.2.2.4 CROSSHEAD SPEED DURING A TEST During crosshead movement, the DRO will display the current velocity of the crosshead. If manually operating the crosshead using the jog keys, the DRO will display the crosshead velocity for your jog movement. When you press and hold a jog button, the crosshead will ramp up to the maximum allowed speed you have setup in the MOTIONS setting. The maximum crosshead velocity for an FMM Test Frame is 40 inches per minute (1016 mm/min). 2.2.2.5 RESULTS AFTER A TEST IS COMPLETED The measured results at the completion of a test are displayed in the Results window. Results, also called coefficients, are displayed in large, easy-to-read text with labels. If tolerances are used, a result that is
2.2.2.2 LOAD BARGRAPH The Load Bargraph displays the measured load in a graphical format. The bargraph fills from the center (zero) position. Tensile loads fill the bargraph from the center upward, while compressive loads fill the bargraph from the center downward. The bargraph uses color to indicate the percentage of load being applied to the load cell sensor relative to the sensor's rated load capacity. The bargraph will display green when the measured load is 0 to 75% of the sensor's rated capacity. The bargraph will display yellow when the measured load is 76% to 90%. The bargraph displays red when the measured load is over 90%. Caution should be exercised when the bargraph is displaying yellow. This indicates that you are operating at the upper range of the load sensor, which is perfectly acceptable. The red color indicates that you are operating at the extreme high end of the sensor's capacity. You should exercise extreme caution in order to not overload the load cell sensor.
"outside the tolerance" displays in red text. 2.2.2.6 TEST STATUS DURING A TEST
During an active test, the bottom Results window displays the current test status. With Cyclic and Hold tests, a cycle counter or countdown timer is displayed.

2.2.2.7 TEST CONTROL FUNCTIONS The DRO window displays essential test control functions. These are described below. SET HOME Press the SET HOME target to designate the position where the crosshead currently is positioned as the "Home" location. Once a test run is completed, the crosshead will return to this exact location so that the next sample can be installed in the testing fixture. NOTE The SET HOME function can be set manually prior to starting a test, or it can be set in the PRE TEST setup stage, where the home position is automatically set once the test is started. START TEST Press the START TEST target to begin your test run. When a test is active, the START TEST label changes to STOP TEST. STOP TEST During an active test run, you may press the STOP TEST target to stop the current test run.
RETURN HOME When you select the SETHOME functionmanually, youwill select the RETURN HOME target to return the crosshead to the designated Home position. In the POST TEST stage, you may configure the crosshead to automatically return to the Home position when a test run has finished. NOTE If the SET HOME was not set before the test, the RETURN HOME target is inactive since there is no home position to return to. 2.2.2.8 DRO BAR The bar separating the top portion of the DRO from the bottom portion may be adjusted. Select the bar and mouse up or down to change the upper and lower window size.

3.0 L1 TEST METHODS- AN OVERVIEW Test templates are supplied standard on your L1 System and are designed to let you create a test in as few as two steps. Your L1 System features these) test templates for the most common types of force measurement testing: • Load Limit Test • Distance Limit Test LOAD LIMIT TEST The Load Limit setup lets you create a load limit test by specifying the limit value and the test speed. Your test will conclude when the load limit is achieved. This test is used when you are interested in determining the amount of deflection/extension the sample exhibits while being pulled or pushed to a load setpoint. 3.2 LOAD HOLD TEST • Break Limit Test • Cycle Limit Test 3.1 The Load Limit setup has an option that lets you specify a hold duration at the load limit. This can be used for creep and relaxation testing. The hold duration may be up to 99,999 seconds (27 hours). NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds. 3.3 DISTANCE LIMIT TEST The Distance Limit setup lets you create a distance limit test by specifying the limit value and the test speed. Your test will conclude when the distance limit is achieved. This test is used when you are interested in determining the amount of load the sample exhibits while being pulled or pushed to a distance setpoint. 3.4 DISTANCE HOLD TEST The Load Limit setup has an option that lets you specify a hold duration at the load limit. This can be used for creep and relaxation testing. The hold duration may be up to 99,999 seconds (27 hours). NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds. 3.5 BREAK/RUPTURE TEST The Break Limit setup lets you create a break test by specifying the break value and the test speed. Your test will conclude when the load drops by a percentage from a previously measured peak load. For example, if the user sets a Break % of 10%, the system will continuously measure the load value. When the load drops by 10% from a previously measured peak value, the data point associated with this drop in load is characterized as the "break point" for the sample under test. This test is generally used when you are interested in determining the maximum (peak) load and the distance at the maximum load.
3.6 CYCLE COUNT TEST The Cycle Count test lets you create a test where the crosshead moves continuously between two setpoint at a specified speed. You will specify the two setpoints and the crosshead velocity. You will also specify the number of cycles or counts to be performed. The test may have a maximum of 99,999 counts or cycles. 3.7 CYCLE DURATION TEST The Cycle Duration test lets you create a test where the crosshead moves continuously between two setpoints at a specified speed. You will specify the two setpoints and the crosshead velocity. You will also specify the duration of the test, i.e., how long the crosshead will cycle for until the test is completed. The test may have a maximum duration of 99,999 seconds (27 hours). NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds.

4.0 L1 TEST TEMPLATES The L1 test templates are designed to help anyone create common test methods for basic force measurement. Using templates, users with very little knowledge of force measurement can create a test in seconds. Tests options are selected from pull-down menus and only relative options to the test method are available for selection. 4.1 COMMON OPTIONS The L1 test templates use common options, methods and features to help users with a very basic understanding of force measurement, to be able to create and perform a force test. These common options are described below. 4.1.1 NAMING YOUR TEST Every test method created requires a unique test name. Your L1 test method may have up to 24 characters. The name may be created using alpha- and numeric characters.
4.1.3 USING EXCEPTIONS (+STOP IF) Exceptions may be optionally applied to your L1 test method. Exceptions are events, that if they occur, cause the test method to stop. EXAMPLE 1 You want to perform a Distance Limit test in order to determine whether a load is achieved prior to the distance limit. During the test, the measured load is exceeding the expected load for the specified distance. In a compression test method, this could mean that something has happened and you are applying too high a load, which could cause damage to the sample under test or the apparatus used in the test. The test stops before the distance setpoint is achieved. EXAMPLE 2 You want to determine the maximum load and distance at maximum load after the sample breaks. The sample has slipped out of the test fixture, therefore, the crosshead is continually moving upwards, but there is no change in load. The test stops since no break load can be detected.
Shown: New Test Name dialog
4.1.2 TEST TYPES Your L1 test method may be either a Tension or Compression Test Type. When a cyclic test is created, the direction on which you want the crosshead to move first is defined by the Test Type selected. If you choose Tension as the Test Type, the first cycle will start with the crosshead moving upwards in the tensile direction. If you choose Compression as the Test Type, the first cycle will start with the crosshead moving downwards in the compression direction. NOTE The Test Type may be Tension or Compression.
The Min Break setting is when you first start looking for a percentage drop in load. It is a precondition- get to 5 lbf first, then starting looking for a 25% drop in load. That indicates a break.
The Break setting is a percentage drop in the measured load after the Min Break was achieved. The software looks for a percentage decrease in the measured load from a maximum value.
Should the crosshead travel to the Distance Limit before it achieved 10 lbf, the test will abort.
Select to Change
PKG08807 - UML1 23
ENGLISH
4.1.4 TEST SPEED All test methods require a test Speed. The Speed setting is the crosshead velocity during the test. NOTE When Return Home occurs, the crosshead will move at the maximum allowed velocity, up to 40 in/min (1016 mm/min).
4.2.2 LOAD UNITS OPTION Load Units let you specify the units of measure that represent your load result and load measurement. Available units of measure for load are N (newton), LBF (pound-force), KGF (kilogram-force) , GF (gram-force) and OZF (ounce-force). 4.2.3 DISTANCE UNITS OPTION Distance Units let you specify the units of measure that represent your distance result and distance measurement. Available units of measure for distance are IN (inch) and mm (millimeter). 4.2.4 SET HOME OPTION Set Home may be YES or NO. If Set Home = YES, the home position, which is the starting position for your crosshead prior to you selecting START TEST, is automatic. If the Set Home option = NO, the operator is required to manually select the SET HOME touch target located to the left of the START TEST touch target. CAUTION You should exercise caution when using Set Home = YES. Damage can occur to your load cell sensor if your Set Home position is incorrect and the crosshead automatically returns to an erroneous position once a test is completed. 4.2.5 SAMPLING RATE (HZ) OPTION Your L1 Series system has a maximum Sampling (Hz) rate of 1000 samples per second. The factory setting is 100 Hz and is usually more than sufficient for capturing peak load, etc. If you need a higher sampling rate, you can change the rate using the numeric keypad. NOTE The L1 software will save up to 100,000 data points for a test run. When using durations for holds or for cycling, make sure to adjust the Sampling Rate (Hz) to a value much lower than 100Hz. At 100 Hz, your test duration cannot exceed 1000 seconds (15 minutes). 4.2.6 USER PROMPT OPTIONS Pre Test settings include the ability to use prompting. Two prompts are available: • Operator Prompt • Batch Prompt
The Speed setting is the velocity for the test. It is the velocity at which the crosshead will travel once the test is started.
4.2 PRE TEST STAGE The Pre Test step provides you with options that may be performed before the test is actually conducted. The Pre Test options are common to all template types. The Pre Test step consists of three sections: Settings, User Prompts and Set Datum.
Shown: L1 Pre Test Stage options
4.2.1 LOCK TEST OPTION When the Lock Test option is set to YES, an unauthorized user is prevented from making changes to the test setup. This option also prevents the test setup from being deleted. The default value for Lock Test is NO. NO means that you can make changes to the test setup once it has been created. NOTE If a test method is Locked, it can only be edited, copied or deleted by the user that created the test. It is a "good practice" to maintain a copy of all tests on a secure server. Use this copy as the master where you can control access and editing.

ENGLISH
4.2.6.2 BATCH PROMPT The Batch Prompt requires the operator performing the test to enter the name of the batch or the sample being tested. When the Batch Prompt is used, the operator is required to enter the name of the sample being tested prior to the test being able to be performed. The Batch Prompt default is OFF (the combo box is not highlighted). 4.2.7 SET DATUM OPTION The Set Datum option lets you configure your test setup to automatically zero the Load and/or Distance when the test is started- when START TEST is pressed. 4.2.7.1 ZERO LOAD If you select the combo box for Zero Load, the load measurement in the display is automatically set to a 0 value at the start of the test- when START TEST is pressed. 4.2.7.2 ZERO DISTANCE If you also select the combo box for the Zero Distance, your distance measurement in the display is automatically set to a 0 value at the start of the test- when START TEST is pressed.
4.2.6.1 OPERATOR PROMPT The Operator Prompt requires the operator performing the test to enter their name when the START TEST touch target is touched. Use this prompt so that the name of the operator performing the test is recorded in the test data. The Operator Prompt provides an audit trail for each test run by operator name. The Operator Prompt default is OFF (the combo box is not highlighted).

4.3 TEST AND DATA STAGES The Test stage is where you specify your limits and crosshead velocity for your test method. This section will describe the options and attributes of the Test stage for each test template type in your L1 software. The Data stage is where you specify your results, i.e., what you want to measure and display. This section will describe how to setup your test method and select or modify the results.
4.3.1 LOAD LIMIT TEST The Load Limit Test is used to measure and report the Distance result at the Load Limit. When you launch the Load Limit test template, the test template menu has these basic attributes: • Type • Target Load • Hold Duration • Speed
Open the TEST stage to setup your test method.
Shown: L1 LOAD LIMIT Test Method setup
Once the TEST stage is completed, use the DATA stage to setup which additional results you want to display and where you want to apply a tolerance for "pass" or "fail" status.
4.3.1.1 TEST TYPE The Test Option launches with the Type = Tension. Tension means you want to perform a Pull test, e.g. you want the crosshead to move in an upward direction. If you want to perform a Compression test (also called a Push test), change the Type to Compression. 4.3.1.2 TARGET LOAD The Target Load value is the load limit setpoint. You want the crosshead to pull your sample until the measured load = your specified Target Load value. Load units may be newtons (N), pounds-force (lbf), kilogram- force(kgf) and for lighter load sensors additionally gram-force (gf) and ounce-force (ozf). You may specify the units of measure for Load using the Pre Test options. Enter numerical data using the keypad at the bottom of the display or using the keyboard supplied with your L1 tablet.

4.3.1.3 HOLD DURATION Use the Hold Duration when you are performing a constant load hold test for creep and relaxation testing. You may specify a duration of up to 99,999 seconds. When a Hold Duration is specified, the Load Limit test will finish once this duration has finished. The default value for the Hold Duration option is null. This means there is no hold at the limit. NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds. 4.3.1.4 TEST SPEED TheSpeedvalue is your test speed.This is the velocity youwant your crosshead to travel at from when you start your test to your Target Load setpoint. Speed units may be either in/min (inch per minute) or mm/min (millimeter per minute). You may specify the units of measure for speed using the Pre Test options. Your L1 System has a speed range from 0.001 to 40.0 inch per minute (0.02 to 1016 mm per minute). 4.3.1.5 EXCEPTIONS The optional exception rules for the Load Limit test are: • Distance • Break % and Minimum Break DISTANCE EXCEPTION Enter a Distance value. If the measured distance equals this value, and the load limit has not been achieved, the test will stop. BREAK EXCEPTION Enter the % Drop value and Minimum Break value to define a break event. Requires entering a Minimum Break also. If a break condition occurs, before the load limit is measured, the test will stop.
4.3.1.6 DATA STAGE The Data stage displays the default results for the test template type. And you may select optional results from a list, also based on the test template type.
Default and primary coefficients are automatically selected.

When a Hold Duration is specified, the Distance Limit test will finish once this duration has finished. The default value for the Hold Duration option is null. This means there is no hold at the limit. NOTE Long duration tests require a smaller sampling rate. The maximum number of data points that can be collected and saved is 100,000. Therefore, use a sampling rate of 1Hz for tests with a duration of 99,999 seconds. 4.3.2.4 TEST SPEED TheSpeedvalue is your test speed.This is the velocity youwant your crosshead to travel at from when you start your test to your Target Load setpoint. Speed units may be either in/min (inch per minute) or mm/min (millimeter per minute). You may specify the units of measure for speed using the Pre Test options. Your L1 System has a speed range from 0.001 to 40.0 inch per minute (0.02 to 1016 mm per minute). 4.3.2.5 EXCEPTIONS The optional exception rules for the Distance Limit test are: • Load • Break % and Minimum Break LOAD EXCEPTION Enter a Load value. If the measured load equals this value, and the distance limit has not been achieved, the test will stop. BREAK EXCEPTION Enter the % Drop value and Minimum Break value to define a break event. Requires entering a Minimum Break also. If a break condition occurs, before the load limit is measured, the test will stop.
