Kikusui PLZ1004W - Remote Sensing Function

6-38 Applied Operation PLZ-4W
6.7 Remote Sensing Function
Remote sensing is a function used to correct the voltage drop caused by the resis-
tance of the load wire when it cannot be discarded. Execute remote sensing to accu-
rately set the resistance, voltage, and power.
Remote sensing improves the transient characteristics in the CR, CV, and CP modes
and thereby achieves stable operation.
■ Remote sensing wiring
Connect the remote sensing on the rear panel (+S) and the positive terminal of the
equipment under test. Likewise, connect the remote sensing (-S) to the negative ter-
minal.
The remote sensing should be wired at the nearest to the EUT.
■ Electric wire used
You do not have to take into account the allowable current as in the load wire. How-
ever, for mechanical strength, use a wire with a nominal cross-sectional area of
0.5 mm
2
or more.
Use crimp terminals for M3 screws for the connection on the PLZ-4W end.
