7.2.1
Output Voltage Calibration
Offset Calibration
a) Set programmed voltage to 5% of full-scale voltage by using the Voltage Knob.
b) Adjust R87 until DVM output voltage reading matches the set voltage as closely as possible.
Full Scale Calibration
a) Set programmed voltage to 90 % of full scale voltage value
b) Adjust R40 until DVM reading equals the set voltage as closely as possible.
7.2.2 Measurement
Calibration
Voltage Measurement Offset Calibration
a) Set programmed voltage to 1 % of full scale
b) Adjust R81 until output voltage measurement on front panel equals DVM reading
Voltage Measurement Full Scale Calibration
a) Set programmed voltage to full scale value
b) Adjust R54 until output voltage measurement on front panel equals DVM reading
Current Measurement Offset Calibration
a) Set programmed load current to 1% of full load
b) Adjust R60 until output current measurement on front panel equal Shunt output current
reading.
