CAUTION
The calibration procedures are performed with the output of the AC power supply module
energized. Do not touch any of the output connections, which could be at hazardous
potentials. Calibration must be performed by qualified personnel who are appropriately
trained to deal with attendant hazards.

QUIPMENT
The recommended calibration equipment is listed in Table below. Equivalent
substitutes are acceptable provided that their accuracy is at least four times
better than the accuracy of the parameter specification that is being calibrated. If
less accurate equipment is utilized, measurement uncertainty may be introduced
that would compromise the validity of the calibration.

Requirements
Recommended
Model
AC Voltmeter
Resolution: 6 1/2 digits
Agilent 34401A
Current Shunt
RFP-A301K-875-XXXX and
RFP-A305K-875-XXXX:
50mΩ, ±0.04%, (15A)
Guildline 9230-15
Adjustable resistive
load (non-reactive)
Load should handle two ranges.
Range 1: 0 to 10 Amps at 125Volt AC
Range 2: 0 to 5 Amps at 250Volts AC
The calibration procedures described here calibrate all output and read back
functions of the RFP AC modules. Measurements derived from primary
measurements of voltage and current do not require their own calibration
coefficients.

ETUP
Calibration must be performed under controlled environmental conditions:
•
ambient temperature must be within 25 °C, +/-5 °C
•
humidity must be less than 80%
•
allow the unit to warm up for 30 minutes at no load prior to performing
the calibration
Refer to Figure 4-14 for a diagram of the test instrument setup.
