4.11 Using Remote Sensing Function
The Remote sensing function detects the output voltage at the sensing input terminal. When the
Remote sensing function is on, the measured value of voltage is the voltage at the sensing input
terminal, and the item symbol is displayed as "SV" on the panel display. The measured values of
power (P, S, Q) and power factor (PF) are also the values that are calculated using the measured
voltage value at the sensing input terminal. However, their item symbols on the panel display are not
changed.
When the Remote sensing function is on, the output voltage at the sensing input terminal is
calibrated by the AGC or Autocal function. Thus, by combining the Remote sensing function with
the AGC/Autocal function, you can compensate the voltage drop due to wiring to the load.
The Remote sensing function can be set to on in the AC-INT, AC-VCA, AC-SYNC, DC-INT, and
DC-VCA modes. However, for the AC mode, it can be set to on only when the waveform is a sine
wave. When the Remote sensing function is on, the waveform cannot be changed to other than a sine
wave. When the mode is changed to ACDC mode, when the signal source is changed to EXT or
ADD, or when the Sequence or Simulation function is selected, the Remote sensing function is
forcibly set to off.


The on/off state of the Remote sensing function is kept even if the output range is changed.

When the Remote sensing function is forcibly set to off, the settings saved in the System
Setting Memory are not updated.

 Cable connection for remote sensing
 Before connecting the cable, turn off this product including its peripherals.
 Pay attention to the withstand voltage of the cable to be connected.
 Do not connect anything to the terminals that are not used.
 Do not input a signal having a different electric potential from the output terminal (for example,
the signal at the secondary side of transformer) into the sensing input terminal.
Connect the sensing input terminal to the output voltage detecting end (for example, load end) using a
cable.
