Configuring CC+CV mode

CC+CV mode is constant current mode (CC mode) with CV mode added to it. You can add
CV mode even while the load is on.

Configure the constant current settings.

To configure the settings, refer to "Configuring CC mode".

Press +CV (SHIFT+MODE) to add CV mode.

The PLZ-4WH switches to CC+CV mode, and “CC+CV” appears on the display.

Make sure that the PLZ-4WH is in the fundamental setting entry
condition.

If SET is not highlighted, press SET/VSET to switch to the fundamental setting entry
condition.

Turn the rotary knob to set the current and voltage.

The value that you can set (current or voltage) changes when you press SET/VSET.

The CC+CV mode settings are complete. Press LOAD to start testing. You can change the
current and voltage even when the load is on.
