Introduction
This manual contains complete operating, maintenance and calibration instructions for the
Compliance West USA Model HT-10KVDC Dielectric Withstand Tester.
The instrument is a bench-type Dielectric Withstand Tester with DC Output, designed for
laboratory testing of components and insulation systems.
The HT-10KVDC 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.
•
The 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.
•
A non-defeatable rampdown circuit returns output voltage to safe levels before test
termination. The Hipot Pass or Hipot Fail light will not light until voltage has been ramped
down by the HT-10KVDC.
•
If a failure is encountered, the high voltage output is disabled, a buzzer sounds, and any
voltage stored in the equipment being tested is bled off by an internal rampdown circuit in
the HT-10KVDC. Voltage discharge progress shown by front panel meter.
•
The failure mode is shown by the front panel LEDs.
Testing features include:
•
Voltage ramp, test time and leakage limit are settable.
•
Voltage ramp and test duration timer are defeatable for specialized testing.
•
Testing may be terminated or continued when a dielectric breakdown is detected.
•
A 120kohm resistor is supplied on the rear panel for leakage current calibration.
Your Tester is warranted for a period of one year upon shipment of the instrument to the original
purchaser.
