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.
