B) Press Test to enter the Calibration Mode and create new calibration settings. (Be
sure you want to enter the Calibration Mode as this will change the laboratory number so
it will show the calibration was not performed by Compliance West USA).
6. Once the Calibration Mode has been entered, the Reset button toggles between the 5
calibration menus: Volt, V1, V2, curr, and bars. Make sure "V1" is displayed on the meter.
7. Hook up a calibrated 1000:1 voltage probe and a calibrated DMM between the Device
receptacle and the Return jack on the front panel.
8. Use the AC/DC selector switch on the front panel to choose which voltage will be
calibrated.
9. Turn the Voltage Adjust on the rear panel to minimum (counterclockwise). Press the Test
button and a voltage number will be displayed on the front panel meter (1500 for AC or
2500 for DC). Be careful as the HT-3000P will be putting out voltage at this point.
10. Turn the Voltage Adjust on the rear panel clockwise until the output on the DMM equals
the appropriate voltage (1500 volts AC or 2500 volts DC) and press the Test button. The
display will now display "V1" again.
11. Press the Reset button until "V2" is displayed on the front panel meter.
12. Turn the Voltage Adjust on the rear panel to minimum (counterclockwise). Press the Test
button and 500 will be displayed on the front panel meter (for either AC and DC). Be
careful as the HT-3000P will be putting out voltage at this point.
13. Turn the Voltage Adjust on the rear panel clockwise until the output on the DMM equals
the appropriate voltage (500 volts AC or DC) and press the Test button. The display will
now display "V2" again. The voltage is now be calibrated.
14. Turn Off the HT-3000P tester.
15. The voltage can be verified by turning on the HT-3000P, running a test, and using the
1000:1 voltage probe to check the meter at different voltages. If the voltages are not within
+/- 2% at each voltage, the voltage calibration must be performed again starting at step 1
above.
Current Calibration Adjustment
1. You must be in Calibration Mode as in step 3 under the Voltage Calibration Adjustment
above.
2. Use the AC/DC selector switch on the front panel to choose AC.
3. Turn the Voltage Adjust on the rear panel to minimum (counterclockwise).
4. Connect the output of the HT-3000P through a 60K ohm, 100 watt high voltage resistor in
series with a calibrated DMM capable of measuring 10.0mA AC and returning to the
Return jack on the front panel of the HT-3000P.
5. In the calibration mode, hit the Reset button until "curr" is displayed on the front panel.
6. Once "curr" is displayed, press the Test button once and 10.0 will be displayed.
7. Slowly increase the variac watching the current flowing on the DMM. Adjust the variac
until 10.0mA AC is displayed on the DMM and then press the Test button.
8. The display will show "hold".
9. Wait until the display returns to "curr". At this point the AC leakage current is calibrated.
10. Turn the Voltage Adjust on the rear panel to minimum (counterclockwise).
11. Use the AC/DC selector switch on the front panel to choose DC.
12. Connect the output of the HT-3000P through a 240K ohm, 100 watt high voltage resistor in
series with a calibrated DMM capable of measuring 5.0mA DC and returning to the Return
jack on the front panel of the HT-2800P.
13. In the calibration mode, hit the Reset button until "curr" is displayed on the front panel.
14. Once "curr" is displayed, press the Test button once and 5.0 will be displayed.
15. Slowly increase the variac watching the current flowing on the DMM. Adjust the variac
until 5.0mA DC is displayed on the DMM and then press the Test button.
16. The display will show "hold".
17. Wait until the display returns to "curr". At this point the DC leakage current is calibrated.
