    Full Voltage indicator is lit to the completion of the test. The Timer Control Switch must be set to ON, or the HT-25KVP dc will test only while the Test Button is pressed. The minimum test time is one second regardless of the setting of the Timer...

  • Page 8: High Voltage Discharge

    High Voltage Discharge The HT-25KVP dc has an internal circuit designed to remove the high voltage, after completion of the dielectric withstand test. The HT-25KVP dc should remain connected to the circuit until the front panel meter shows that the output voltage has dropped to a safe level.

  • Page 13 ITEM NAME FUNCTION When ON, Dielectric breakdown detect will be activated. When in DEFEAT position, test will continue regardless of a dielectric breakdown, but it can be stopped by the excess HIPOT leakage limit. NOTE: The RAMP switch, and TIMER switch must also be in the DEFEAT position, otherwise the buzzer will sound.

    2 seconds, and the meter will display “d” with the Test Duration set time in seconds. Leakage Current Level Adjust 1. Connect the HT-25KVP dc to a correctly rated source of supply and turn ON the tester. 2. Push the RESET button. The TEST indicator should light, indicating that the HT-25KVP dc is ready.

    9. Release the TEST button to terminate the test. High Voltage Test Time Adjust This procedure sets the length of time the HT-25KVP dc will conduct the high voltage test. The test time is specified by the safety agencies, and is tied to the test voltage. Most safety agencies will allow a much shorter test (usually 1 second vs.

    HT-25KVP dc. If the Timer Control switch is set to ON, the HT-25KVP dc will conduct the high voltage test for the amount of time set in the Test Duration procedure.
  • Page 19 Ramp Time: May be set too fast. A very fast ramp time may allow input capacitors to act as short circuits, triggering a Leakage Current Fail light and terminating the test. Consider to have a slower Ramp Time, by increasing the time; see Ramp Time Adjust.
  • Page 20 Full voltage is produced at the output immediately. Test will continue only as long as the TEST button is held in, minimum one second. The HT-25KVP dc will NOT shut down on a dielectric failure, but the front panel Hipot Fail light will flash to indicate a dielectric breakdown. The Hipot Pass light will not light at the completion of a successful test.

  • Page 21: Maintenance And Calibration

    Section Service Information The HT-25KVP dc is warranted to the original purchaser for a period of 1 year. This warranty does not cover problems due to misuse or neglect. Malfunctions which occur within the limits of the warranty will be corrected at no charge.

  • Page 22: Entering Calibration Mode

    ALL ADJUSTMENTS. Entering Calibration Mode NOTE Only enter into this mode if the HT-25KVP dc unit needs a re-calibration on any of the parameters of Voltage Meter or Leakage. Turn Off the HT-25KVPac unit. Hold in both the Test and Reset buttons.

  • Page 23: Voltage Meter Verification

    Press the Test button and turn up the Voltage Adjust to compare the front meter of the HT- 25KVP dc unit vs. the external volt meter, tolerance most be +/-0.2KV full scale. If one value is out of the specified tolerances, the HT-25KVP dc unit needs a voltage meter re-calibration. Follow the Voltage Meter Re-Calibration procedure.

  • Page 24: Leakage Meter Verification

    Reading on the external meter should be +/- 0.1mA full scale. If one value is out of the specified tolerances, the HT-25KVP dc unit needs a leakage current re-calibration. Follow the Leakage Current Re-Calibration procedure.
  • Page 25 (mA scale) equals the number showed on the front meter of the HT-25KVP dc unit, then, press the Test button and the front display will show “hold” for a few seconds, wait until the front display show again "L1" again.
