CALIBRATION PROCEDURES
This instrument 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 instrument 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 instrument 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 Equipment Required:
The following equipment will be needed to properly calibrate your instrument.
1). Digital Multimeter with the minimum ranges;
AC Voltage: 5,000 volts
AC Current: 25mA range.
DC Current: 2000uA range
2). 500K/50Watt resistor
CALIBRATION PROCEDURE:
Model 2925 and 2935
To enter the calibration mode the instrument 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.
For model 2925 and 2935 the display will show:
Press the SET key for kilovolts calibration, Down Arrow key () for milliamps.
For model 2945 the display will show:
Press the SET key for kilovolts calibration, Down Arrow key () for milliamps, and the
EXIT key for insulation resistance calibration.
