WARNING
CALIBRATION ADJUSTMENTS ARE PERFORMED ON ENERGIZED CIRCUITS.
EXERCISE CAUTION AT ALL TIMES, AND USE A NON-CONDUCTIVE TOOL FOR
ALL ADJUSTMENTS.
Calibration and Software Version Information
This will allow the user to see the version of the software as well as who performed the last
calibration.
1.
Turn off the HT-PR tester.
2.
Hold in the
Reset
button while turning on the tester.
3.
The meter will display 3 items:
A) The model number of the tester.
B) The version of the software
C) Laboratory number to designate who performed the last calibration:
(1= Compliance West USA, 2= another company)
Voltage Calibration Adjustment
Use the following procedure to calibrate the output voltage.
1.
Ensure that all test leads are removed from the HT-PR.
2.
Turn OFF the HT-PR tester.
3.
To enter the
Calibration Mode
you MUST follow the following sequence:
- Hold in both the
Test
and
Reset
buttons.
- Turn on the HT-PR tester.
- Release the
Test
button, release the
Reset
button, press and hold the
Reset
button, press
and hold the
Test
button, release the
Test
button, and then release the
Reset
button.
4.
If the correct sequence was entered, the display will read "Sure", if not, start again at step 2
above.
5.
While "Sure" is displayed on the screen you can:
A) Press
Reset
to exit out of the
Calibration Mode
and keep all of the currently
programmed calibration settings or
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, L1, L2, bars, r1 and r2. 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.
For the HT-3000PR 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-PR 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.
