Daily Operation Test
The operation of the HT-10KVDC should be checked daily by conducting the tests described in
the
Initial Checkout Procedure section of this Manual.
Testing Products
This section describes how to conduct a test. Testing can be terminated at any time by pressing
the red RESET button; item 1.
1.
Connect your Tester to a correctly rated source of supply and turn it on.
2. Plug the black lead into the Return jack; item 8. Plug the red lead into the Output jack;
item 9.
3. Connect the alligator clips of the leads across the circuit or part being tested. Keep in mind
that the black lead is connected to earth ground.
4. Press the RESET button; item 1. The blue TEST light; item 2, should light, indicating that
the HT-10KVDC is ready to test.
5. Push the TEST button, item 2. The HT-10KVDC will either:
•
Ramp the voltage at the rate set by the Ramp Time Procedure, if the Voltage Ramp
Switch; item 13, is set to DEFEAT.
•
Immediately energize the high voltage output if the Voltage Ramp Switch is set to
DEFEAT.
6.
•
If the Failure Shutdown Switch; item 21, is ON, and if the leakage current of the circuit
under test is too high, the Excess Leakage LED; item 3, will light, and the test will
terminate.
•
If the Failure Shutdown Switch is set to DEFEAT, and the requirements of Table 3-3 are
met, the HT-10KVDC will continue to test. Voltage output may sag if the power
required by the circuit is beyond the capabilities of the HT-10KVDC.
7.
•
If the Test Timer Switch; item 12, is ON, the HT-10KVDC will conduct the high voltage
test for the amount of time set in the Test Duration procedure.
•
If the Test Timer Switch is set to DEFEAT, the high voltage test will continue only while
the TEST button; item 2, is pressed.
8. If a insulation system breakdown is detected, and
•
The Failure Shutdown Switch; item 21, is ON, the voltage will ramp down to a safe
level, the Hipot Fail LED; item 5, will light, the buzzer will sound, and the test will
terminate.
•
The Failure Shutdown Switch is set to DEFEAT, and the requirements of Table 3-3 are
met, the Hipot Fail LED will light and the test will continue.
9. If no breakdown is detected, the high voltage will ramp down, the Hipot Pass LED; item 6,
will light, and the red RESET switch; item 1, will light.
10. Do not disconnect the leads from the equipment being tested until the Hipot Pass or Hipot
Fail light has lit, and the meter indicates less than 50 volts.
