OPP function protects the power supply when the output power exceeds rated power. The output is shut down
under OPP mode.
OTP function protects the power supply when the instrument produces abnormal high temperature during
operation process. The output is shut down under OTP mode.
3.14 Operation Mode
3.14.1 Constant Voltage Operation
(1)
Connect load to output terminal.
For the safety, turn off the output before connecting the load to output terminals of (+) and (-).
(2)
Set the current limit value.
Press
[I-set]
until “Current” is shown on the LCD,
the panel operation is set to current value input mode. Set
the desired value by using the number buttons or the rotary knob.
(3)
Set the desired output voltage value.
Press
[V-set
until “Voltage” is shown on the LCD, the panel operation is set to voltage value input mode
. Set
the desired change value by using the number buttons or the rotary knob.
(4)
Start the output.
Press
[On/Off]
to enable output. Now, the meter displays the actual output measurement value.
(5)
Constant voltage mode confirmation.
Check whether the CV indicator is on or not to make sure the output operation is under the constant voltage
mode. If the CC indicator is on, it needs to increase its current limit value to ensure that the output operation
is under constant voltage mode.

is under constant current mode.
3.14.3 CV/CC Switch
When the output current level reaches the setting with the Output ON, the CC indicator turns red. The instrument
operates in Constant Current mode. When the output voltage level reaches the setting, the CV indicator turns
