Protection Functions
The electronic load has seven kinds of protection functions. When a
protection function is activated, an alarm occurs.
You can set the value to detect for the OCP, OPP, and UVP functions.
You can choose the action (load off or limit) that is performed by the OCP
and OPP functions from the menu.
You can stop an alarm by pressing ENTER. The alarm will be activated
again if its cause has not been eliminated.

Turn off the power of the DUT within 30 seconds.
If reverse voltage is detected when you are using the PLZ164WA/
PLZ664WA in a test where a DC power supply is connected in series
with the DUT, see “When the DC power supply and the DUT are
connected in series, and turning on/off of the DUT” (p. 5-5) in the User’s
Manual.
Overheat Protection (OHP)
Activated when the temperature of the internal power unit exceeds 95°C.
Alarm Input Protection

• Switching Interval
You can set the switching interval by specifying a frequency and duty
ratio or by specifying an amount of time.
Setting a Frequency and Duty Ratio
Use the FREQ/DUTY key and the rotary knob to set the values. Press
FREQ/DUTY to switch between the frequency and the duty ratio.
Setting a Time
Use the Th/TL (SHIFT+FREQ/DUTY) key and the rotary knob to set a
time. Press Th/TL (SHIFT+FREQ/DUTY) to switch between the high
and low sides of the switching time.
Functions Useful for Battery Discharge Testi ng
• Elapsed Time Display (Count Time)
You can measure the time from the start of discharge to the cutoff
voltage. You can enable the elapsed time display from the menu.
• Auto Load-Off Timer (Cut Off Time)
You can use this function to turn the load off after a specified amount of
time has passed since the start of discharge and measure the closed
circuit voltage immediately before the load is turned off. You can set the
auto load-off timer from the menu.

Other Settings
• Soft Start
In CC mode and CR mode, you can use this function to raise the
electronic load’s current gradually. This is useful in cases such as when
voltage application begins at the same time that the load is turned on
and when voltage is applied while the load is on and there is no load
input.
You can enable the soft start function from the menu.
• Locking the Electronic Load
You can press LOCK (SHIFT + LOCAL) to lock the electronic load and
disable all operations other than the turning on and off of the load,
sequence execution, and memory recall. To release the lock, press and
hold LOCK (until you hear a confirmation sound).
• Short Function
You can use this function to specify the maximum current value (CC
mode) or the minimum resistance value (CR mode) instantaneously.
To activate the short function, press SHORT (SHIFT + SLEW RATE) while
the load is on. Press SHORT again to deactivate the short function.
• Response Speed
This is the speed at which the input current and voltage values are
detected and controlled through negative feedback. You can set the
response speed in CC mode and CR mode.
You can set the response speed from the menu.
When you operate an electronic load in parallel or at high speeds (with
the switching function for example), refer to “Notes about Parallel and
High-Speed Operation” on the CD-ROM to set the response speed.
• Slew Rate Setting
When the current changes rapidly because you are using the switching
function or for some other reason, set the slew rate to determine the rate
at which the current is changed.
Press SLEW RATE, and set the value using the rotary knob.
• Resetting to the Factory Default Settings
While holding ENTER, turn on the power switch. The contents of the
memory are deleted.
