The following equipment is required for the calibration procedure:
 6 ½ digit precision digital multimeter
 Shunt for current calibration (Necessary if the maximum
output current of the power supply is greater than the
maximum current the multimeter is capable of measuring)
 DC source with an output up to 10VDC and accuracy of at
least ±0.1% (for external analog input calibration)
 5 kΩ resistor with accuracy within ±0.1% or better (for external
analog input calibration)
Current Calibration
- If the maximum output current of the power supply is within the
current limit of the DMM, then use the wire connections shown in
Figure 31 to calibrate current.
- If the maximum output current of the power supply is greater than
the current limit of the DMM, then a current shunt must be used.
The wire connections between the power supply and the DMM will
be setup like Figure 32.
