Specifications and Controls
Introduction
This manual contains complete operating, maintenance and calibration instructions for the models
HT-2000S, HT-2800S, HT-3000S and HT-4200S Dielectric Withstand Testers, please see Table 1 for
specifications.
The instrument is a bench-type Dielectric Withstand Tester with AC and/or DC Output, designed
for production line testing. The HT-S features automatic one button operation, with numerous safety
features designed to protect the operator:
The Return Lead is directly connected to ground potential for operator safety. Test can be
immediately terminated at any time by pressing the
RESET
button. Before the test can commence, the unit
must be armed by pressing the
RESET
Button. The test will not begin until the
TEST
button is pushed.
If a failure is encountered, the high voltage is immediately shut down, a buzzer sounds, and any
voltage stored in the equipment being tested is bled off by a resistor bank in the HT-S unit. The voltage
discharge progress is shown by the front panel meter. Failure modes are shown by the front panel LED's
for quick troubleshooting.
Convenience and testing features include:
a.
Test results are determined quickly, without operator intervention.
b.
Operator instructions are printed on the rear panel for quick reference.
c.
The HT-S allows custom setups for Voltage Ramp time, Test time, Leakage limit and Ground
Continuity limit.
d.
The Ground Continuity test can be defeated by a switch on the rear panel for testing of products
using a two wire power supply cord.
e.
DC Voltage is discharged by a resistor bank within the HT-4200S, HT-3000S or HT-2800S upon
test completion. Discharge progress is shown on the front panel meter.
f.
The HT-S meets all safety agency criteria for automatic production line Dielectric Withstand
Testers.
g.
Your Tester is warranted for a period of one year upon shipment of the instrument to the original
purchaser.
