When the remote sensing function is being used
The sensing point of the remote sensing function is the other end of the wire connected to the
remote sensing terminal on the PLZ-4WH rear panel. Connect the end of this wire to the
output of the DUT that you want to sense. Measurements are made at the sensing point for
determining the protection-activation-values of overvoltage protection (OVP), overpower
protection (OPP), and undervoltage protection (UVP).
If a wire is disconnected during remote sensing, the PLZ-4WH and the DUT may be
damaged. Make sure that wire connections are secure.
Details about overcurrent protection (OCP)
You can set the value at which OCP is activated.
You can also set the action that is performed when OCP is activated. By factory default, the
action is set to LIMIT (the current is limited).
To change the action that is performed ("LIMIT" or "LOAD OFF"), from the menu, select "1.
Setup" > "2. Protect Action" > "OCP."
Setting the overcurrent-protection-activation value
You cannot set the overcurrent-protection-activation value in CC mode.

Make sure that the load is off.
If the LOAD LED is lit, press LOAD to turn the load off.
2
Press OPP/OCP until OCP is highlighted on the display.
The OPP/OCP key lights. Pressing OPP/OCP switches between OCP and OPP.
3
Turn the rotary knob to set the overcurrent-protection-activation value.
Details about overpower protection (OPP)
You can set the value at which OPP is activated.
You can also set the action that is performed when OPP is activated. By factory default, the
action is set to LIMIT (the power is limited).
To change the action that is performed ("LIMIT" or "LOAD OFF"), from the menu, select "1.
Setup" > "2. Protect Action" > "OPP."
Setting the overpower-protection-activation value
You cannot set the overpower-protection-activation value in CP mode.
