Self-test is a sequence of checks made by the tester to ensure the unit is functioning correctly.
You may run Self-test at any time by pressing the SELF-TEST soft-key in the Top Level menu.
Before commencing self-test, please ensure that there is nothing touching any of the test nodes on the top surface of the tester. In particular, remove all test fixtures and transformers.
As the self-test is running, the front panel display will indicate progress using a horizontal bar:
CAUTION:- If the connections have been correctly made to the Safety Interlock, then a complete test will be executed, including high voltage testing up to 7000V. These voltages will be present on all the test nodes on the top surface of the tester.
At the end of the self-test, you should see the following screen:
To ensure operator safety, the high voltage sources are not checked until about 10 seconds after the start of self-test.
If the safety interlocks are not ‘made’ before the end of this period, high voltages will not be generated or checked, and at the end of the test, you will see the following message:
Without a safety interlock system the unit cannot perform any high voltage self tests, hence the high voltage sources are disabled.
If there is a failure at any point in the self-test, you will see a display similar to the following:
The message shown on the lower two display lines will depend on what caused the failure.
In the unlikely event that your tester continues to fail, please make a note of the failure message and contact your Voltech supplier for service.
