Operating Instructions

Theory of Operation

The HTT-1S is designed to be a solution for fast and easy function testing of

the HT-S series of 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-1S is designed to verify calibration points at a fixed value.

The HTT-1S, 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-1S 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-1S to the tester outputs.

2. Set all three switches on the HTT-1S to ‘PASS’.

3. Verify passing result on the Tester.

4. Set the Ground switch on the HTT-1S to ‘FAIL’; set both other switches to

‘PASS’.

5. Verify Ground failure on the Tester.

6. Set the Leakage switch on the HTT-1S to ‘FAIL’; set both other switches to

‘PASS’.

7. Verify Leakage current failure on the Tester.

8. Set the Hipot switch on the HTT-1S to ‘FAIL’; set both other switches to

‘PASS’.

9. Confirm high voltage output by watching for a spark in the Arc Detect window

of the HTT-1S; 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-1S 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-1S is functioning correctly.

Introduction and Specifications

Introduction

This manual contains complete operating, maintenance and calibration

instructions for the Compliance West USA Model HTT-1S Function Tester.

The instrument is a portable function tester used to verify proper

operation of hipot and ground continuity testers. The HTT-1S is intended to be

used as a calibration verification tool.

The HTT-1S is warranted for a period of one year upon shipment to the

original purchaser.

Specifications

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

Table 1: Specifications of the HTT-1S

Maximum current capability of GROUND test circuit: 30 Amps

Ground Test time should be 3 seconds Max and rest 10 s for currents above 10A

Setting of PASS for Ground Circuit: 0.025 ohm resistor *

Setting of FAIL for Ground Circuit: 0.1 ohm resistor *

Setting of PASS for Leakage Current: open circuit

Setting of FAIL for Leakage Current: short-circuit

Maximum voltage capability of HIPOT test circuit: 3000VAC / 4200VDC

Setting of PASS for Hipot test: open circuit

Setting of FAIL for Hipot test: arc-over at 750 + 400VAC / 1050 + 560VDC

HT-1S model only works with the following S series testers:

-HT-2000S

-HT-2800S

-HT-3000S

*Note: Switch contacts resistance and connectors can add up to 0.03 to the total

resistance. For customized values see product label.
