Before the calibration, please click “Config” button to set the COM interface, address and baud rate. The
default Com port is COM, and the default baud rate is 9600. Please make sure that the baud rate and
address in the software and in power supply are the same.
5.2 Voltage calibration
Step 1: Prepare to use multi-meter to measure the output voltage, and connect the voltage meter to the
power supply according to the diagram in the above windows.
Step 2: Click “Linked” button. It will go into Calibration mode, the Rmt and Cal indicators will light up.
Step 3 : Fill the first voltage value you measured from the multi-meter to the blank of “0.000V”, and
click “OK” button to confirm the value.
Step 4: Fill the second voltage value you measured from the multi-meter to the blank of “0.000V”, and
click “OK” button to confirm the value.
Step 5: Fill the third voltage value you measured from the multi-meter to the blank of “0.000V”, and
click “OK” button to confirm the value.
5.3 Current calibration
Step 1: Prepare to use multi-meter to measure the short circuit current, and connect the current meter to
the power supply according to the diagram in the above windows.
Step 2: Click “Linked” button, it will go into Calibration mode, the Rmt and Cal indicators will light up.
Step 3: Fill the first current value you measured from the multi-meter to the blank of “0.000A”, and click
“OK” button to confirm the value.
Step 4: Fill the second current value you measured from the multi-meter to the blank of “0.000A”, and
click “OK” button to confirm the value.
