Hi,

I have just purchased a

I want to use it to drive between 1 and 4 less at a constant current of 700ma, i cannot work out how to get it to use constant current mode?

Regards

Hello Wayne Richards,
Here is a method:
1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want.
2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-current potentiometer to make output current reach preset value.
Best regards.
