11.15 Remote Sensing

This switches the voltage used for measurement. When the remote sensing is on, the sensing input
terminal voltage is used. When it is off, the output terminal voltage is used.
By combining with AGC or Autocal, a voltage drop due to wiring to the load can be compensated.
When the remote sensing is on, the output voltage detection point corrected by the AGC or Autocal
function is switched to the sensing input terminal. When AGC or Autocal is off, only the detection
voltage used for measurement display is switched.
Remote sensing ON or FB setting can be selected in the AC-INT, AC-VCA, AC-SYNC, DC-INT,
and DC-VCA modes. For in the AC mode, it can be selected only when the waveform is a sine wave.
It is turned off when the Sequence or Simulation is selected.
When setting remote sensing to FB, the voltage feedback detection point is changed from inside
(output terminal) to outside (sensing input terminal), and AGC or Autocal cannot be set. Remote
sensing can be set to FB only when DIP or RIN is connected and the function of external control is
set to DevCtrl. For external control, see 11.26.

*40 ： It is used to control DIP or RIN. Put DIP or RIN near this product.
*41 ： It is enabled switching ON⇔FB or OFF⇔FB only when the output is OFF. The cable
connecting the input terminal of DIP or RIN to the output terminal of this product should be
as short as possible (3 m or less) and use twisted or parallel.
