PLZ-5W SR Series Setup Guide
Connecting the Sensing Cables
Using the remote sensing function makes it possible to change a voltage measurement point
from a load input terminal to an arbitrary sensing point. By setting sensing points at the EUT
end, influences such as voltage drops caused by the resistance of the load cables can be
reduced, and the load current can be stabilized.
To use remote sensing, connect the sensing cables to the sensing terminals of the PLZ-5W
SR and the EUT end, and enable the remote sensing function.
Unlike the load cables, there is no need to consider the current capacity for the sensing
cables. However, for adequate mechanical strength, use wires whose nominal cross-sec-
tional area is 0.5 mm
2
or greater.
1
Open the load input terminal cover
2
Connect the sensing cables.
Remove the two short bars from the sensing terminals, and then connect the cables.
Short bars must be connected to the sensing terminals when remote sensing is not in
use. Store the short bars in a safe place.
3
Adjust the positions of the lock plates for the load input terminal cover
.
4
Close the load input terminal cover
.
CAUTION
• Risk of damage to the internal circuitry. Do not wire the sensing terminals while the
POWER switch is turned on.
• If the remote sensing cables come loose while remote sensing is in use, the PLZ-5W SR
and EUT may be damaged. Be sure to connect the cables securely.
• If you are not using remote sensing, remove the sensing cables, and be sure to attach the
two short bars to the sensing terminals.
Sensing cables: Use cables whose cross sectional area is at least 0.5 mm
2
and twist them together.
