3.2 Output on/off
The output of the power supply could be switched on or off through this

again.
When the output of the power supply is enabled, “CV”, “CC” or “Unreg”
will be displayed in the lower right corner of the display. “CV” indicates
that the supply source is in constant voltage state, “CC” indicates that the
power supply is in constant current state and “Unreg” indicates that the
power supply is operating in unstable state (Neither in constant voltage
nor constant current status).
For example: if the power supply output is in constant voltage state, the
actual output voltage is 5V and the actual output current is 3A, the display
will show as follows:
When the output of the power supply is off, the “OFF” annuciator in the lower left
