Page 6: An Introduction To Dielectric Withstand Testing With The Ht-3000
Currents of as little as 5 mA at 120 volts can cause death, and the HT-3000 is capable of generating 20 mA AC at up to 2000 volts, and 5 mA DC at up to 2800 volts. The HT-3000 has been designed to minimize exposure to high voltages. -

The equipment under test should be connected to the HT-3000 and then left alone by the operator. After the operator is clear of the Tester and the equipment under test, he should press the RESET Button, then the TEST Button, with his right hand. -
Page 8: Defeating The Ground Check
If the Test Return Lead is not properly connected, a dielectric withstand failure may energize exposed dead metal. Additionally, the HT-3000 may not recognize the failure. The test will continue for its normal length of time, and the HT-3000 may show a "PASS". -
Page 9: High Voltage Dielectric Withstand Test
If the the HT-3000 is being used to conduct an AC test and the leakage current adjustment is set to 20 mA and almost all examples of the model being tested fail, the primary circuit capacitance of the equipment may be too high to allow the AC dielectric withstand test to be used. This is due to the AC voltage charging all capacitors connected between primary voltage and ground. -
