Page 5: An Introduction To Dielectric Withstand Testing With The Ht-2800
The dielectric withstand test generates voltages of up to 2800 volts dc at potentially lethal current levels. Currents of as little as 5 mA at 120 volts can cause death, and the HT-2800 is capable of generating 5 mA at up to 2800 volts. Because there is no zero volts crossing point as there is for ac voltage, dc voltage is considered the more dangerous of the two. -

The equipment under test should be connected to the HT-2800 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 7: Defeating The Ground Check
In some cases where the leakage current of the equipment under test is high, but still within the testing parameters of the HT-2800, and the ground continuity of the chassis at the point of attachment of the Test Return Lead clip is marginal (within 1% of the three ohm failing point), the ground continuity test light may trigger after the test has commenced. -

The test time is counted from the time the Full Voltage LED is lit to the comp letion of the test. If the green Hipot Pass LED lights, the test cycle has been successfully completed. The equipment under test is in accordance with the preset test parameters. The HT-2800 is ready to test the next piece of equipment. -
