Maintenance
1) If the supply voltage is normal and the CC and CV indicators are not
on or the digits are not displayed after starting up, the fuse may be
blown or there may be other malfunctions. Turn off the power switch
and unplug the power cord, then replace the fuse or seek
professional advice.
2) At constant voltage state, if the output voltage is less than the
preset value and the CC indicator is on (current protection), the
device will automatically switch to the constant current working
state. Users should check the load or increase the maximum current
as required (adjust the CURRENT knobs clockwise).
3) At constant current state, if the output current is less than the
preset value and the CV indicator is on (open circuit voltage
protection), the device will automatically switch to the constant
voltage working state. Users should check the load or increase the
maximum voltage as required (adjust the VOLTAGE knobs clockwise).
4) At constant voltage state, if the device is unstable, the AC supply
voltage may be lower than 99V/198V. If any malfunction is serious
and cannot be resolved, please contact your local dealer.
