BK Precision MR Series - External Current Programming Calibration

Calibration 65
9.6 External Current Programming Calibration
To perform the external current programming calibration:
1. Connect the DMM to the external analog control terminals of DB25 connector (+ on the DMM to Pins 10 and 24,
- on the DMM to Pin 22(GND)) on the rear of the power supply, as shown in the gure below:
Figure 9.5 Current Programming Calibration Diagram
2. Set the DMM to a DC voltage measurement. Select the EXT_CURR parameter in the CAL menu and press
. The following will be displayed:
The P: 1/2 signies there are 2 points to be calibrated and the current calibration point is 1.
3. Input the voltage reading from the DMM in the METER parameter by using the numeric keypad and press .
4. Repeat this procedure by entering the meter readings for points 2.
