Compliance HTT-1R Function Testers

Compliance HTT-1R Function Testers

The Compliance HTT-1R is designed to be a solution for fast and easy function testing of all dielectric withstand and continuity testers, including high current models delivering up to 30 amps. It allows function tests of all three failure modes to ensure that your tester is functioning properly.

The HTT-1R is designed to verify calibration points at a fixed value.

The HTT-1R, used daily, will prove function of the safety testers before shifts or before testing of a lot of products. It is provided with three switches which simulate passing and failing equipment for ground continuity, high leakage between primary circuits and ground, and dielectric withstand failure between primary and ground circuits. While all three switches can be simultaneously set for failing modes, we recommend that the HTT-1R be set with one failure at a time to ensure that your testers are
functioning correctly.

A proper test plan would be constituted of the following tests:

  1. Connect HTT-1R to the tester outputs.
  2. Set all three switches on the HTT-1R to ‘PASS’.
  3. Verify passing result on the Tester.
  4. Set the Ground switch on the HTT-1R to ‘FAIL’; set both other switches to ‘PASS’.
  5. Verify Ground failure on the Tester.
  6. Set the Leakage switch on the HTT-1R to ‘FAIL’; set both other switches to ‘PASS’.
  7. Verify Leakage current failure on the Tester.
  8. Set the Hipot switch on the HTT-1R to ‘FAIL’; set both other switches to ‘PASS’.
  9. Confirm high voltage output by watching for spark in Arc Detect window of HTT-1R; verify dielectric breakdown failure on the Tester.

The above plan is presented in more detail in the Operation Section of this Manual; showing proper connection of the HTT-1R to any dielectric t tester nd ny high current ground continuity tester you may wish to test.

If any of the tests above return unanticipated results, you may have  problem with your tester. It is recommended that it be removed from service until the problem can be resolved. Section 4 of this manual also has troubleshooting information to help you determine if the HTT-1R is functioning correctly.

HTT-1R Front Panel Features

Item Name Function
1 Chassis Banana Receptacle If a Ground Continuity Hipot is being checked, connect to the chassis ground output of the Hipot. If a ground bond tester is being used, connect it to the high current output.
2 Return Banana Receptacle Connected to the Return Lead on the Hipot or Ground Continuity Tester, which is normally connected to dead metal parts of the equipment undergoing dielectric test.
3 Output Banana Receptacle Connected to the high voltage output of the Hipot Tester being checked.
4 Arc View When Dielectric Breakdown function is being checked, a spark will be visually demonstrated the breakdown occurred.
5 Ground Test Switch When set to FAIL, an open ground is simulated and the tester should stop testing and indicate a failure. When set to PASS, a normal passing result is simulated.
6 Leakage Test Switch When set to FAIL, an excess leakage condition is simulated and the tester should stop testing and indicate a failure. When set to PASS, a normal passing result is simulated. Used for Dielectric Testers only.
7 Hipot Test Switch When set to FAIL, a dielectric breakdown will be simulated and a spark can be seen in the Arc View window. When set to PASS, a normal passing result is simulated. Used for Dielectric Testers only.
