6.3.- Check of high voltage cables
To check the HIGH VOLTAGE cable they should be disconnected so
of the unit like of the equipment under test. The equipment UM2B is
able to provide very high voltage, then THE CABLES SHOULD BE
IN PERFECT STATE TO AVOID ELECTRIC SHOCKS OR
ERRORS AND IMPRECISION IN THE MEASURES.
When an anomaly is detected in the cables or you want to verify its correct state, you
can do this simple test.
We only need a multimeter that indicates us the electric continuity or discontinuity.
To check each cable we will come in the following way:
1. Disconnect the high voltage cable in their both ends.
2.
Check the discontinuity between active and body. We take the high voltage‟s
connector that goes into the UM2B unit. We place one multimeter test tip in contact
with the connector‟s interior tip (active) and the other multimeter test tip in contact
with the connector‟s metallic cover. Multimeter should say discontinuity.
