Tech Tips
Raise the lower boom to at least a 45 degree
angle.
Visually check that all jumpers, voltage source
from the dielectric tester and the return are still
connected once the unit is in position.
Step 12
Plug in and turn on the dielectric tester. Raise
the voltage control to the required voltage listed
on the test sheet. Monitor the volt and current
meters to verify that the test is working correctly.
If the current meter value stays below the Max
Leakage continue test until complete, record
readings, return the voltage control to 0, turn off
and unplug the dielectric machine.
If the current meter value exceeds the Max
Leakage at any point during the test return the
voltage control to 0, turn off and unplug the
dielectric machine. Begin troubleshooting to
determine why the boom will not pass the
dielectric test. Reference Tech Tip #51 for
further troubleshooting help.
