Remote Sensing
When the load wiring is long, the voltage drop caused by the wiring’s resistance cannot be
ignored. “Remote sensing” is a function that can be used to compensate for this voltage drop.
To accurately set the resistance, voltage, and power, use remote sensing.
Remote sensing makes operation more stable by improving the transient characteristics in
the constant-resistance (CR), constant-voltage (CV), and constant-power (CP) modes.
Unlike the load wires, there is no need to consider the current capacity for the wires that you
connect to the sensing terminals. However, for adequate mechanical strength, use wires
whose nominal cross-sectional area is 0.5 mm
2
or greater.
1
Turn the POWER switch off.
2
Connect the sensing terminals to the DUT using sensing wires.
Connect the positive remote sensing terminal on the rear panel (+S) to the positive
terminal (+) on the DUT. In the same way, connect the negative remote sensing
terminal (-S) on the rear panel to the negative terminal (-) on the DUT. Connect the
wiring as close to the DUT as possible.
CAUTION
• Never wire the sensing terminals while the POWER switch is turned on. Doing so may
damage the internal circuitry.
• If a wire is disconnected during remote sensing, the PLZ-4WH and the DUT may be
damaged. Make sure that wire connections are secure.
