Appendix G – Calibration Procedure
This tester has been fully calibrated at the factory in accordance to our published specifications. It has been
calibrated with standards traceable to NIST. You will find in this manual a copy of the "Certificate 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 specifications.
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 verification can only be made while operation in Test mode.

The following standard equipment will be needed to properly calibrate your tester.
A Standard AC Voltmeter with 5,000 Volts range
A Standard AC Voltmeter with 6 Volts range
A Standard DC Voltmeter with 6,000 Volts range
A Standard DC Voltmeter with 1,000 Volts range
A Standard AC Ammeter with 30 A range
A Standard AC Milliammeter with 20 mA range
A Standard DC Milliammeter with 5 mA range
A Standard Resistor 100 k/20Watt/1500VAC
A Standard Resistor 1 M/0.25Watt/300VDC
A Standard Resistor 50 M/0.25Watt/1000VDC
1. Calibration Initialization
