Adjustment of the Leakage Current Level
DC Leakage Current can be set to levels of up to 5 mA. Use the 120 kohm resistor and the
leakage current adjustment control on the rear panel; items 16 and 18. Reset the high voltage
level and test duration after this adjustment.
Since most controls used in this adjustment are on the rear panel, place the instrument so
the rear panel faces you. Refer to Figures 3-1 and 3-2.
1.
Determine the proper voltage setting for the desired leakage current level, using
the formula: Volts=(Leakage Current in mA)*(120)
2.
Adjust the Test Time control; item 15, on the rear panel to approximately the middle of its
travel.
3.
Adjust the Leakage Limit control; item 16, on the rear panel to its maximum clockwise
position.
4.
Make sure there are no test leads connected to the Tester.
5.
Push the RESET button; item 1. The blue TEST light; item 2, should light, indicating that
the Tester is ready to test.
6.
Push the TEST button; item 2.
7.
Use the Voltage Adjust control; item 10, to set the voltage calculated in Step 1 of this
procedure, then push the RESET button.
8.
Connect the red lead to the Output jack; item 9, and the black lead to the Return jack, item
8. Connect the alligator clips across the calibration resistor; item 18, on the rear panel.
9.
Push the TEST Button; item 2, and then the RESET Button; item 1, repeatedly while
decreasing the Leakage Limit; item 16. The lowest setting which lights the green Full
Voltage light; item 4, is correct. If the red Excess Leakage light; item 3, lights instead, the
adjustment is set too low.
10. You can pull the shaft out of the Leakage Limit control; item 16, if tamperproof settings are
desired. It can be reinserted.
11. Reset the high voltage level and test duration before testing products. See the adjustment
procedures below for reference.
