OVP ON/OFF

In the static mode, use the keys CH1-CH4 to select the OVP channel to be ON/OFF; and then use the OVP button to switch the OVP status. OFF means to close OVP, and the OVP voltage display means to be ON.

Setting the OVP voltage

In the static mode, use the buttons CH1-CH4 to select the OVP channel to be set, and then use the OVP button to switch the OVP status tos status with voltage display. And adjust the OVP value through the Left/Right+ UP/DOWN knobs, or directly enter the OVP by the Number keys+ ENTER.

OCP Function

OCP ON/OFF

In the static mode, use the buttons CH1-CH4 to select the OCP channel to be ON/OFF, and then use the OCP button to switch the OCP status. OFF means the OCP is turned off, and the OCP current display means to be ON.

Setting the OCP current

In the static mode, use the buttons CH1-CH4 to select the OCP channel to be set, and then use the OCP button to switch the OCP status to the status with the current display. Use Lef/Right +UP/DOWN knob to adjust the OCP value. And you can also complete the setting directly through the number buttons.

Switch between static mode and LIST mode

Switch between static mode and LIST mode
You can switch between the two modes by using the buttons CH1-CH4 in either the static mode or the LIST mode.

LIST selection
Use the buttons F1-F4 to enter the LIST list, and select the LIST list to be used by the totary knob or UP/DOWN button. After selecting, press the buttons F1-F4 again to return,

Keyboard LOCK Function

Press and hold the button LOCK to lock the keyboard, and press and hold again to unlock.

System configuration
