Mountz Torque LTT Torque Analyzer Operation Manual

The torque analyzer is designed for calibrating tools, joint testing, auditing, and measuring torque. Torque tools go out of calibration with use. To maintain consistent accuracy, torque tools must be checked periodically for wear or defective parts. A power or hand torque tool is a measuring tool that must be properly calibrated and maintained. The LTT-Series is an advanced torque testing and documentation solution. Using a quality torque tester makes a safer world through accuracy and precision. Controlling torque is essential for companies to ensure their product’s quality, safety, and reliability aren’t compromised.

Entering data for the Tool Test is done using the PC Windows based Calibration Program. See the Screen above. Select the “Tool Tests” tab. Enter the relevant information on this screen such as the Test Name, which is the name by which the test will be identified on the LTT. Then enter all required information on the screen because once the tool test is activated on the LTT no changes can be made with the units, tolerances or other information. There is a field for comments to include user specific information. The torque sensor being used for the Tool Test must be identified. This is done to prevent a test being run on a torque sensor with an inappropriate range. When entering the “Sensor Model” this must match with the sensor identification that was used to identify the torque sensor when it was calibrated. The case of alphanumeric characters will be ignored. If the transducer to be used for the test is connected you can click on the "Read" button next to the Sensor Model field and the field will be automatically populated. If you are not sure about how the transducer is identified, unplug the torque sensor from the LTTunit and plug it back in.

Note: * the Sensor Model identification appears on the LTTscreen during the initialization.

Select Quick Test

Tool Tests

Start Stop Clear Memory Choose the function desired, from the menu list, by using the Up /Down keys and use Enter key to finalize the selection highlighted in reverse video. Select is used to select the desired test from a list of tests that have been downloaded. When an operator selects this he/she will view an introduction for 3 seconds that provide directions, and then this will display: Choose Tool Test from List of available tests. Use Up /Down keys to toggle between tests. Use Enter to select test. After the short introduction the operator will see the tool tests displayed and can select the desired test. Quick Test: By selecting Quick Test the operator can run a quick test using the currently selected parameters of the meter such as Mode, Units, and Tolerance etc. After selecting Quick Test, Press the Enter key. The test starts immediate- ly and the operator can start collecting data. Once the operator collected the number of reading desired then press the Tool Test "soft" button that now reads Quick Test. Then the operator can select Stop to end the test. When the operator connects to the Interface Program and click on Download Results, the Quick Test data is down- loaded. The file name will be Quick Test with associated Date and Time. If the operator performs several different Quick Tests he/she will have different Time and/or Date files for each test. Start begins collecting test data. The tool name will be followed by a colon and then the number of data points collected. Stop ends the test. This is required as some users may want to collect 10 data or others may want to collect 25 points or more.

Clear Memory allows the test points to be cleared in the meter itself. The operator will be asked for confirmation before the action takes place. This function should only be used if the readings have been downloaded to the PC or test data is invalid for some reason.

Once all desired tests are run the operator can return to the PC to download all Tool Tests stored

in the LTT. If they choose to add comments they can do so by checking the "Require Comments" check box. During a particular test download the operator will be given the opportunity to add further notes to the file stored on the PC.

Angle Test Operation

All angle tests must be entered using the PC Windows based Calibration Program. Once this is done the tests can be accessed using the soft key on the LTT. Entering data for the Angle Test is done using the PC Windows based Calibration Program. See the Screen above. Select the “Angle Tests” tab. Enter the relevant information on this screen as needed for type of angle test that will be used. Note: * The Bolt Audit Mode is an additional feature that is only available with LTT Bolt Audit model (Item # 072995)

Torque+Angle Mode A. Angle Threshold B. Torque Threshold C. Allow Angle Ratchet

Bolt Audit Mode A. Initial Torque Threshold B. Final Torque Threshold

Spindle Audit Mode A. Initial Torque Threshold B. Low Angle Threshold C. High Angle Threshold

Angle Set-Up A. Angle Threshold B. Angle Polarity C. Angle Encoder

Bolt Audit Explanation This feature is designed for auditing the torque applied to a fastener for a test such as determining relaxation after a fas- tener has been tightened. An initial and final torque threshold is entered into the bolt audit mode fields. As an example the initial torque value could be 70% of the desired torque on the fastener and the final torque would be the nominal value for which the fastener was previously tightened. In this case, if the nominal torque is 500 lbf.ft, the initial torque threshold would be entered as 350 lbf.ft, 70% of the nominal value.

The purpose of the bolt audit function is to report the degree of movement from the initial torque threshold to the final torque threshold. The torque analyzer will display the final torque threshold and the total angle displacement, which has occurred from the initial torque threshold and final torque threshold. Spindle Audit Explanation 1. Spindle Free Test: The operator turns on the tightening spindle and the spindle starts rotation, the LTTbegins to count angle immediately, and when the spindle stops, the LTTwill display and record the final angle, and final peak torque. Set up the initial values. The Initial Torque should be entered as zero so that the Angle will begin to be counted as soon as the spindle starts moving.

2. Spindle within required tolerance:

Set up the initial values such as the Initial Torque, the Low Angle Threshold and the High Angle Threshold. An example would be a Torque of 15 N.m, Low Angle Threshold of 40 degrees and a High Angle Threshold of 50 degrees. When the tightening spindle reaches 15 N.m, the Angle begins to be counted. If the spindle stops between 40-50 degrees, the LED shows green, and the display shows the final Angle and the final Torque.

If the spindle stops before reaching 40 degrees the LED will show red and the display shows the final result.

If the spindle stops after exceeding 50 degrees the LED will show red and the display shows the final result.

Torque Sensor Calibration

Torque Sensor Calibration should only be performed by an operator with the necessary calibration wheels or arm and weight sets or by a calibration lab. Mountz offers calibration services to perform this function. LTT calibrations are done in conjunction with a PC Windows based Calibration Program. The program is easy to use and guides the user through the calibration steps. Once the program is started and connected to the LTTmeter, a button "Start" is provided to start the calibration. All the needed information must be entered in the appropriate text boxes. This includes information such as the Sensor Model, Serial Number, the Full Scale torque value, the units of calibration and the transducer type (Bridge or Brushless). There is also a Scroll box to allow setting of the Calibration Interval. The default is 6 months but that can be changed. Once all required information is entered, the Start button is clicked, and its function changes to "Continue" as shown in figure below and procedural information will be given in the large text box. A 2-point calibration should work well in all but exceptional circumstances. Once the calibration is complete the calibration data will be stored in a Mountz "Smart" torque sensor using the ARCII protocol. For non-smart torque sensors the calibration data will be stored in the LTT internal memory. A sophisticated error correction algorithm assures that the data written to and retrieved from memory is always correct. Once the calibra- tion is finish, Torque Values will be displayed in the Torque Window allowing for verification of calibration data points. The "Delete Device" option allows the ability to delete non-smart sensors or transducers records from the LTTTorque Analyzer. In order to delete the device record for a non-smart sensor, the non smart sensor or transducer must be con- nected to the LTT Torque Analyzer. Ensure the LTT Torque Analyzer is powered on. Connect the non-smart device to the LTT. Use the scroll up or scroll down arrows on the keypad of LTTto locate the device to be deleted. Press enter on the LTTkeypad to complete the selection. Launch the torque meter interface program and go to the Sensor Calibration tab. Press "the Read From Sensor" tab located just above the "Delete Device" tab to read in the device information. A Calibration Data window should appear with details of the non-smart device. Click on exit to exit the Calibration Data win- dow. Please ensure to validate the details displayed on the screen to ensure the selection is as desired, as the "Delete Device" function will delete the device record. A non-smart device can only be added back in by going through the cali- bration process. Press the "Delete Device" tab to remove the device record for the non-smart device. If there is a need to delete multiple non-smart devices, the above steps must be repeated for each non-smart device.

Note for Force & Load Sensors When performing a Load Cell Calibration, if choosing a 2 point calibration, load at 10% and 100%. If performing a 3 point calibration and load at load at 10%, 50% and 100%. The calibration program will guide you through the calibration by text in the information box. By selection in the Calibration Type you can select Compression Only, Tension Only or Both if the Load cell supports this. Type in the appropriate Full Scale value and select the units desired. The "Delete Device" option allows the ability to delete non-smart sensors or transducers records from the LTTTorque Analyzer.

The LTT interface program contains a Tab for Data Logging. The actual plot on the Screen is Torque vs. Time. If you have an Angle enabled transducer the Torque and Angle data will be collected in a .csv file. The data collection begins when you click the "Start" button and ends when you click the same button which changes to "Stop" after the data collec- tion begins. The data collected is saved in the PC. The actual file path is as follows: Computer>Local Disk(C)>Users>User Profile Name>AppData>Roaming>Mountz>Mountz Torque Meter Interface Program>Program File Version>Tool Test Results>Operator Name If you use this function frequently you probably will want to create a shortcut to this folder. The .csv file can be opened using Excel. You can use Excel to plot this data in a variety of formats or by using other Windows based tools of your choice. There is also an Excel Spreadsheet with a Macro as an example of Plotting Torque and Angle. This is available on the LTT CD in the folder Excel Macro for Torque and Angle. Open this Excel file, highlight the Torque and Angle data, click the Graphing Icon that is on the spreadsheet, the Torque and Angle will be plotted for you. If you have your own Torque and Angle data you can just replace the example data with your own, highlight it and click the Graphing Icon to plot it.

This Spreadsheet gives an example of Plotting Torque and Angle Values. Simply highlight the cells containing the values of Angle and Torque and click on the Graphing Icon (below). If you have collected Torque and Angle values, using the LTT Data Logging Program, you can use this Template to Plot Torque and Angle. Simply substitute your own values for those on the left. The data collected is saved in the PC. The actual path is as follows: Computer>Local Disk(C)>Users>User Profile Name>AppData>Roaming>Mountz>Mountz Torque Meter Interface Program>Program File Version>Steaming Data Files>Operator Name By default, the setting for Hidden files and folders is "Don't show hidden files, folders and drives".
