Voltage Meter Verification
1.
Turn Off the HT-5000P ac/dc 200mA unit.
2.
Turn the Voltage Adjust to minimum.
3.
Select the type of output voltage with the AC/DC Switch.
4.
Set up a 1000:1 probe with and external volt meter has is shown on Figure 4-1.
5.
Turn On the HT-5000P ac/dc 200mA unit.
6.
Press the Test button and turn up the Voltage Adjust to compare the front meter of the HT-
5000P ac/dc 200mA unit vs. the external volt meter, tolerance most be +/- 100V full scale.
7.
If one value is out of the specified tolerances, the HT-5000P ac/dc 200mA unit needs a
voltage meter re-calibration. Follow the Voltage Meter Re-Calibration procedure.
Figure 4-1.
Voltage Measurement with 1000:1 High Voltage Probe
Voltage Meter Re-Calibration
1.
Turn Off the HT-5000P ac/dc 200mA unit.
2.
Select the type of output voltage with the AC/DC Switch.
3.
Set up a 1000:1 probe with the volt meter has is shown on Figure 4-1.
4.
Enter to
Calibration Mode
. See Entering Calibration Mode procedure.
5.
Select the top calibration voltage point by pressing the
Reset
button until V1 is shown on
the front display of the HT-5000P ac/dc 200mA unit.
6.
Turn the Voltage Adjust on the front panel to minimum (counterclockwise). Press the
Test
button and a voltage number will be displayed on the front panel meter (04.00 for AC or
06.00 for DC). Be careful as the HT-5000P ac/dc 200mA will be putting out voltage at this
point.
7.
Turn the Voltage Adjust on the front panel clockwise until the output on the external
voltage meter equals the number showed on the front meter of the HT-5000P ac/dc 200mA
unit, then, press the Test button to record the new top calibration voltage point in the
internal memory. The front display on the HT-5000P ac/dc 200mA unit will show "V1"
again.
