Adjustment of the High Voltage Test Time
This procedure sets the length of time the HT-3000P-1A-AC will conduct the high voltage
test. Consult the safety agencies for the test time for the type of equipment being tested. If a
different test time is required, use this procedure to set it.
1.
Connect the HT-3000P-1A-AC to a correctly rated source of supply and turn the power
switch to the I or ON position. Push the RESET button. The yellow TEST indicator should
light, indicating that the HT-3000P-1A-AC is ready to test.
2. Turn the Test Time potentiometer. As soon as the potentiometer starts turning, the meter
will display “d” and the value can be set in 1 second increments from 1 to 60 seconds.
Operating Techniques
The following paragraphs describe how to operate your HT-3000P-1A-AC Dielectric
Withstand Tester. Before proceeding with testing, the HT-3000P-1A-AC tester should be set up
for production line testing. See Section above before continuing.
CAUTION:
High voltage is generated by the HT-3000P-1A-AC. Although the chassis of the
equipment under test is grounded by the HT-3000P-1A-AC, a risk of shock exists. Exercise
care when using the HT-3000P-1A-AC.
Daily Operation Test
The operation of the HT-3000P-1A-AC should be audited daily by conducting the tests
described in the Initial Checkout Procedure section of this Manual.
Test results
1. Excess leakage LED/Buzzer
It means the equipment being tested failed. The equipment should be set aside, reworked and
retested with acceptable results before it is shipped. General interpretations of test failures are
included in Section 1, "Using the HT-3000P-1A-AC Dielectric Withstand Tester".
2.
Hipot fail LED/Buzzer
It means the equipment has detected a dangerous arc and stops the test. It is a safety feature,
it is recommended to review the connections and the device under test before applying voltage
again.
