BK Precision MR Series - CC Calibration of External Current

Calibration 67
9.8 CC Calibration of External Current
To perform the calibration procedure for the constant current source of the external current programming by resistor
mode:
1. Connect the external analog control terminals of DB25 connector (Pins 10, Pin 22(GND)) on the rear of the power
supply, as shown in the gure below:
Figure 9.7 CC Calibration of External Current Diagram
2. Select the EX _I_CC parameter in the Calibration menu and press . The following will be displayed:
The P: 1/4signies there are 4 points to be calibrated and the current calibration point is 1.
The four points use 0Ω, 2.5kΩ, 7.5kΩ, 10kΩ.
3. Press , the calibration will start, if the resister is not inserted or not correct, the following will be displayed:
4. If the resister is correct, the following will be displayed, press .
5. Repeat this procedure by entering the meter readings for points 2 – 4.
