How can I check if my high voltage test lead is good for a HVA series test instrument?

Test leads generally get a lot of abuse during their lifetime and are often subject to damage and possible failure.

While having a broken test lead can lead to some frustrating troubleshooting to find the guilty culprit, there are some basic tests that can be done to either help eliminate or to blame the test lead for a possible faulty test result.
‍

Using a conventional multimeter in Ohm mode, check the resistance of the main conductor and shield.

‍Note: The test lead should be removed from the test equipment and obviously not energized for these tests to be carried out.
‍

HVA28TD, HVA34TD, HVA45TD: The main conductor should have less than a few Ohms from end to end to show continuity.
Questions regarding the shield continuity should be addressed by calling HV Diagnostics.
‍

HVA30/34: The main conductor should have less than a few Ohms from one end to the other end - that is full continuity.
The Shield should show continuity (less than a few ohms).

HVA60: Depending on the version of test lead, the main conductor should have approximately 10kOhms, 2.6kOhms or 1.2kOhms from end to end.
The Shield should show continuity (less than a few ohms).

HVA90: The main conductor should read approximately 1.2kOhm from end to end.
The Shield should show continuity (less than a few ohms).

HVA120: The main conductor should read approximately 1.2kOhm from end to end.
The Shield should show continuity (less than a few ohms).
