NOTE
PLZ-4W
• You can prevent the settings from being changed inadvertently during measure-
ment by pressing the LOCK (SHIFT+LOCAL) key to enable the lock.
■ Accurately proportionating the external resistance variation
and input current variation
You can use the pre-set resistors OFS and FSC on the PLZ-4W rear panel to adjust
the current offset value and maximum current value, respectively. The adjustment
enables control that is accurately proportional to the external resistance. The adjust-
ment is valid for the specified range. If you change the range, make a readjustment.
• Adjustment is made by actually supplying the load current. Prepare the power
supply to be tested.
For proportional control
1. Turn on the load.
Set the external resistance to 0 .
2.
3. Turn OFS to set the current reading of the display measurement section
to 0 A.
4. Set the external resistance to 10 k.
5. Turn FSC to set the current reading of the display measurement section
to 100 % of the selected range.
6. Turn off the load to finish the adjustment.
For inverse proportional control
Set the external resistance to 10 k at step 2. Set the external resistance to 0  at
step 4.
