5)
Start the output:
Press [OUTPUT] to enable output, now, the meter displays the
actual output measurement value.
6)
Constant voltage mode confirmation
Check whether the C.V. indicator is on or not to make sure the
output operation is under the constant voltage mode. If the C.C.
indicator is on, it needs to enlarge its current limit value to assure
that the output operation is under constant voltage mode.

Constant Current Operation
1)
Connect load to output terminal:
For the safety, when connect the load to output terminals of (+)
and (-), it must turn off the power.
2)
Select output range:
Turn on the power after the load is well connected, select the
adequate operation range by pressing [SHIFT][8V/20A] or
[SHIFT][20V/10A]).
3)
Set the voltage limit value:
Press [V SET], the panel operation is set to voltage value input
mode, set the desired change value by using the number key or
the wheel knobs (the wheel knob can be used together with [<] or
[>] to adjust the resolution.

Set the desired output current value:
Press [I SET], the panel operation is set to current value input
mode, change to the desired value by using the number key or
the wheel knobs (the wheel knob can be used together with [<] or

Programming Over Voltage Protection, OVP
Set OVP level and the protection circuit of the OVP status.
1)
Input the value of the Over Voltage protection limit value and set
the OVP status.
2)
Confirm the function of OVP (Over Voltage Protection):
Adjust the output voltage up near to OVP level to confirm the
OVP function, when the OVP circuit is triggered, the OVP loop
will drop the output voltage near to zero, now, the OVP indicator
will be blinking.
3)
Clear the OVP function:
