Appendix G – Calibration Procedure
This tester has been fully calibrated at the factory in accordance to our published specications. It has been calibrated using
standards with accuracies traceable to the National Institute of Standards and Technology (NIST). You will nd in this manual
a copy of the “Certicate of Calibration”. It is recommended that you have this tester recalibrated and a safety check done at
least once per year. Slaughter recommends you use “Calibration Standards” that are NIST traceable, or traceable to agencies
recognized by NIST to keep this tester within published specications.
End user metrology standards or practices may vary. These metrology standards determine the measurement uncertainty ratio
of the calibration standards being used. Calibration adjustments can only be made in the Calibration mode and calibration
checks or verication can only be made while operation in Test mode.
Calibration Equipment Required:
The following standard equipment will be needed to properly calibrate your tester.
A Standard AC Voltmeter with 5,000 Volts range
A Standard DC Voltmeter with 6,000 Volts range
A Standard DC Voltmeter with 1,000 Volts range
A Standard AC Milliammeter with 20 mA range
A Standard DC Milliammeter with 5 mA range
A Standard Resistor 100 kΩ/20Watt/1500VAC
A Standard Resistor 1 MΩ/0.25Watt/300VDC
A Standard Resistor 50 MΩ/0.25Watt/1000VDC
1. Calibration Initialization
To enter the calibration mode the tester must be in the OFF position. Using a pen or small screwdriver, press and hold the
recessed calibration key on the rear panel, then turn on the input POWER switch. The display will show:
To calibrate AC voltage please follow procedure on next paragraph, to calibrate other parameters use rotary know to scroll to
the desired calibration point, then follow procedure on relative paragraph below.
When the calibration process is completed successfully and the tester accepts the entered calibration data it will output
one short “beep” and advance to the next calibration point, otherwise the tester will output two short “beeps” and will not
advance to the next calibration point.
2. To calibrate AC voltage
Please connect a standard 5000V AC Voltmeter to the HV and RETURN connectors.
Then press the TEST button on the front panel. The tester will provide around 5000VAC on the output connectors and the
display will show:
Then the display will show a value around 5000 Volts.
