5.2 Current Calibration
Follow the steps below to perform the current calibration:
1. Connect the shunt resistance, DMM and Electronic load to the output of the power supply
as shown in the figure below:
Figure 5.2 – Current Calibration Diagram
2. Set the DMM to a DC voltage measurement. Set the Electric Load in CV mode, the voltage
set 5V. Select the CURRENT parameter in the Calibration menu and press . The following will
be displayed:
The 1/4 signifies there are 4 points to be calibrated, and the current calibration point is 1, and
press to start calibration.
3. When METER parameter is blinking, input the current, that voltage reading from the DMM
divided by the shunt resistance, in the METER parameter by using the numeric keypad .
4. Repeat this procedure by entering the meter readings for points 2 – 4.
5.3 OVP Calibration
The overvoltage protection (OVP) calibration can be executed right after the voltage calibration or
the user can select OVP in the Calibration menu.
Follow the steps below to perform the overvoltage protection calibration:
1. Disconnect any load from the output terminal of the power supply.
