Operating Instructions

Theory of Operation

The 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 tester and any high current ground continuity tester

you may wish to test.

If any of the tests above return unanticipated results, you may have a 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.

Section 2

Introduction and Specifications

Introduction

This manual contains complete operating, maintenance and calibration instructions for the Compliance

West USA Model HTT-1R Function Tester.

The instrument is a portable function tester used to verify proper operation of hipot and ground

continuity testers. The HTT-1R is intended to be used as a calibration verification tool.

The HTT-1R is warranted for a period of one year upon shipment to the original purchaser.

Specifications

Specifications for the HTT-1R are listed in the following table:

Section 3

Operation

This section describes how to set up and use the HTT-1R.

Setting up the HTT-1R

As shipped from the factory, the HTT-1R container contains the following items:

•The HTT-1R Function Tester

•This manual

•Return cable (P/N:

00-HTTRGGL)

•Output and chassis cable (P/N:

00-HTTRHV)

Remove the HTT-1R from the container and place it on a non-conductive test bench. Plug the cables;

follow instructions on Set up procedure. To begin testing, follow the directions in Section 1 above.

Note: This setup will work for any hipot / ground bond tester having a standard wall receptacle and

return banana jack connectors.

Cable P/N 00-HTTRHV Cable P/N 00-HTTRGGL

Figure 1: HTT-1R Front Panel Features

Item Name Function

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.
