Voltage and Current Adjustment Knob Operation
There are 3 adjustment modes for the voltage and current levels, that is, Mode 1
and Mode 2. Mode 1: Before setting, push the knobs to adjust the voltage and
current levels. Mode 2: adjust directly, no need to push the knobs. And these 2
modes can be shifted by pushing the voltage adjustment knob and the current
adjustment knob at the same time and holding for 2 seconds.
Mode 3: remote control mode (programmable control mode).
