Adjustment of the High Voltage Ramp Time
This procedure sets the high voltage ramp time between 0.5 and 5 sec. The factory setting of one
second is adequate for most situations. Refer to Figures 3-1 and 3-2 for location of items.
1.
Make sure there are no test leads connected to the Tester.
2.
Push the RESET button; item 1. The blue TEST light; item 2, should light, indicating that
the Tester is ready to test.
3.
Push the TEST button; item 2.
4.
The voltage meter; item 7, will show the output voltage and hold. Use the Ramp Time
control; item 14, to change the ramp time. Turning the control clockwise will increase
ramp time, and turning it counterclockwise will decrease it.
5.
Push the TEST button; item 2, and RESET button; item 1, repeatedly, changing the Ramp
Time; item 14, until the desired value is reached.
6.
You can pull the shaft out of the Ramp Time control if tamperproof settings are desired. It
can be reinserted.
Adjustment of the High Voltage Level
This procedure controls the high voltage level used in the dielectric withstand test. The HT-
10KVDC is factory set for 0 volts DC. Use the procedure below to set it.
1.
Turn the Test Timer switch; item 12, to the DEFEAT position. (The HT-10KVDC will
supply voltage while the TEST button; item 2, is held in.)
2.
Make sure there are no test leads connected to the HT-10KVDC.
3.
Press the RESET button; item 1. The blue TEST light; item 2, should light, indicating that
the HT-10KVDC is ready to test.
4.
Push and hold the TEST button; item 2.
5.
While the TEST button is pressed, the voltage will ramp. Adjust the high voltage control;
item 10, until the desired voltage is reached.
Adjustment of the High Voltage Test Duration
This procedure sets the amount of time the tester will conduct the high voltage test. The test
duration of the HT-10KVDC is factory set for 2 seconds. If a different test duration is required,
use this procedure to set it.
1.
Make sure there are no test leads connected to the tester. Set all three rear panel switches
"ON".
2.
Push the RESET button; item 1. The blue TEST light; item 2, should light, indicating that
the Tester is ready to test.
3.
Push the TEST button; item 2.
4.
The Full Voltage LED; item 4, will light. The test time is from when the Full Voltage LED
lights to the end of the test.
5.
After the test is complete, adjust the Test Time control; item 15.
6.
Push the RESET Button; item 1, then the TEST Button; item 2, and time the new test
duration. Adjust the Test Time control until correct.
