3-4 For First Time Users PLZ-4W
Warming up the PLZ-4W
To perform stable measurements, allow the PLZ-4W to warm up for at least 30 min-
utes before starting tests. While the PLZ-4W is warming up, check the operation of
the PLZ-4W and the connection of the equipment under test.
Voltage drop in the load wire
If the load wire is long, a voltage drop occurs due to the resistance of the cable. If
the amount of voltage drop caused by the wire cannot be ignored or if you wish to
set the resistance, voltage, and current accurately, execute remote sensing before
making measurements. For the setup procedure of the remote sensing function, see
section 6.7, “Remote Sensing Function.”
How to use the operation panel
The PLZ-4W is controlled from the operation panel on the front panel. If you make
an invalid selection or perform an invalid key operation, a beep is sounded to notify
the error. In particular, please familiarize yourself with the use of the SHIFT key
that changes the key function.
•
For a description of the functions of each key, see chapter 4, “Names and Func-
tions of Parts.”
•
To prevent the possibility of electric shock, never touch the load
input terminal while the equipment under test is connected and the
power is turned on. When touching the load input terminal, be sure
to turn off the equipment under test.
■
Function of the LOAD key
If you press the LOAD key when the load is turned off, the LOAD LED illuminates,
and the load turns on. If you press the LOAD key when the load is turned on, the
LOAD LED turns off, and the load turns off.
• There is a danger of breakdown. Turn off the load when applying the out-
put of the equipment under test to the PLZ-4W. Then, turn the load on. If
you are making the connection with the load turned on, be sure to turn off
the output of the equipment under test.
If a relay or electromagnetic switch is inserted between the load input ter-
minal and the output terminal of the equipment under test, turn on the
relay or electromagnetic switch when the load is turned off. Then, turn the
load on.

How to use the rotary knob
The rotary knob is used when setting values such as the current and resistance.
Turning the rotary knob to the right increases the value and turning it to the left
decreases the value. In addition, you can press the rotary knob to switch between
coarse adjustment and
fi ne adjustment. When the “
↓
” shown at the upper right cor-
ner of the screen is large, coarse adjustment is active; when it is small, fi ne adjust-
ment is active. When setting a value, use coarse adjustment to set the value roughly,
and then switch to
fi ne adjustment to set value precisely.
• You can traverse the full scale of values by turning the rotary knob ten and a few
turns. Fine adjustment changes values at 1/10 of the rate of coarse adjustment.
