Figure 5.6 – CC Calibration of External Voltage Diagram
2. Select the EXT VOLTAGE CC parameter in the Calibration menu and press . The following will
be displayed:
The P: 1/4signifies 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 insert 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.
5.8 CC Calibration of External Current
Follow the steps below 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 figure below:
