key to enable the output
Note: when key is gray, the power supply is in SET mode, then the VFD
displays the set voltage and current; when the key is lit, then the power supply is
in METER mode, the actual voltage and current display on the VFD. When the
output is OFF, the ---- will display at the current display area.
3) Set the voltage value
Adjust the voltage, then press to lit the key (indicates it is in the METER mode),
make sure that the set value and output value are same, and if the current displayed on
