    Full Voltage indicator is lit to the completion of the test. The Timer Control Switch must be set to ON, or the HT-20KVPac will test only while the Test Button is pressed. The minimum test time is one second regardless of the setting of the Timer Control...

  • Page 8: High Voltage Discharge

    High Voltage Discharge The HT-20KVPac has an internal circuit designed to remove the high voltage, after completion of the dielectric withstand test. The HT-20KVPac should remain connected to the circuit until the front panel meter shows that the output voltage has dropped to a safe level.

    5. Push the RESET button. The TEST button should light. 6. Push the TEST button. 7. The HT-20KVPac tester will conduct a test. The meter will read a voltage, hold, and return to zero. During the test, the voltage can be adjusted using the Voltage Adjustment knob. At the end of the test, the Full Voltage, Hipot Pass, and RESET switch indicators should be lit.

    2 seconds, and the meter will display “d” with the Test Duration set time in seconds. Leakage Current Level Adjust 1. Connect the HT-20KVPac 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-20KVPac is ready.

  • Page 16: Voltage Adjust

    Voltage Adjust This procedure controls the high voltage level used in the dielectric withstand test. The HT-20KVPac is factory set for minimum voltage as shipped from the factory. Use the procedure below to set it. 1. Make sure there are no leads connected to the tester.

  • Page 17: Setting The Failure Shutdown Switch

    Set up tester to correct parameters for unit to be tested using the previously described procedures. 2. Connect the HT-20KVPac to a correctly rated source of supply and turn it on. Plug the black lead into the Return receptacle. Plug the red lead into the Output receptacle.

  • Page 18: Test Results

    If the Shutdown Limit switch is set to DEFEAT, and the requirements of Table 4-3 are met, the HT-20KVPac will continue to test. Voltage output may sag if the power required by the circuit is beyond the capabilities of the HT-20KVPac.
  • Page 19 Shutdown Limit Setting: May be set too low. This would cause normal input capacitor charging to draw more that the preset leakage current limit, triggering a Leakage Current Fail light, and terminating the test. Consider raising the acceptable leakage current level; see Adjustment of the Leakage Current Shutdown point.
  • 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-20KVPac will NOT shut down on a dielectric failure, but the front panel Hipot Fail light will flash to indicate a dielectric breakdown. The...

  • Page 21: Maintenance And Calibration

    Tester. A 1-year calibration cycle is recommended to maintain the specifications given in Section Service Information The HT-20KVPac is warranted to the original purchaser for a period of 1 year. This warranty does not cover problems due to misuse or neglect.

  • Page 22: Entering Calibration Mode

    ALL ADJUSTMENTS. Entering Calibration Mode NOTE Only enter into this mode if the HT-20KVPac unit needs a re-calibration on any of the parameters of Voltage Meter or Leakage. Turn Off the HT-20KVPac unit. Hold in both the Test and Reset buttons.

  • Page 23: Voltage Meter Re-Calibration

    Press the Test button and turn up the Voltage Adjust to compare the front meter of the HT- 20KVPac unit vs. the external volt meter, tolerance most be +/-0.1KV full scale. If one value is out of the specified tolerances, the HT-20KVPac unit needs a voltage meter re-calibration. Follow the Voltage Meter Re-Calibration procedure.

  • Page 24: Leakage Meter Verification

    Press the Test button and slowly turn up the voltage comparing the leakage current on front meter with the external meter. Reading on the external meter should be +/- 0.1mA. If one value is out of the specified tolerances, the HT-20KVPac unit needs a leakage current re-calibration. Follow the Leakage Current Re-Calibration procedure.
  • Page 25 "L1" again. Select the bottom calibration leakage point by pressing the Reset button until L2 is shown on the front display of the HT-20KVPac unit. Turn the Voltage Adjust on the front panel to minimum. Press the Test button and a leakage number will be displayed on the front panel meter (1.0).
