Requirements
Before calibrating, the “+”output terminal must be connected to the
“+S” terminal and the “–”output terminal must be connected to the
“–S” terminal using the included shorting bars/pins.
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 33.
