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 32to 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.
