Turning the Load On and Off
The load is on when current is flowing through the PLZ-4WL or when the PLZ-4WL is
supplying current. The load is off when current is not flowing through the PLZ-4WL and the
PLZ-4WL is not supplying current. You can turn the PLZ-4WL’s load on and off by pressing
LOAD. The terms “load on” and “load off” appear frequently in this manual, so please
remember them.
Turning the load on
1
Make sure that the load is off.
2
Apply the output of the DUT to the PLZ-4WL.
If you are using a relay, electromagnetic switch, or other device in the connection
between the load input terminals and the output terminals of the DUT, turn the device
on.
3
Press LOAD to turn on the load.
■
Starting with the load turned on
By factory default, the load is not turned on unless you press LOAD after turning on the
POWER switch.
To start the PLZ-4WL with the load turned on, from the menu, select “2. Configuration” > “2.
Power On” > “Load On” > “ON.” Turn the power switch off and then on again to enable the
settings.
■
Displaying the time that has elapsed since the load was turned on
This function, which displays the time that has elapsed since the load was turned on, is useful
when used in conjunction with undervoltage protection (UVP) in discharge tests of batteries
and capacitors. By factory default, the time is not displayed.
To display the time from load on to load off, from the menu, select “1. Setup” > “1. Function” >
“Count Time” > “ON.” Turn the power switch off and then on again to enable the settings.
■
Using an external control signal to turn the load on and off
You can turn the load on and off using external control signals from a relay or other device.
■
Gradually raising the PLZ-4WL’s input current
In constant current mode (CC mode), you can set the PLZ-4WL to raise its input current
gradually (soft start).
CAUTION
To avoid damaging the PLZ-4WL, be sure to follow the proper procedures for turning the
load on and off.
