11.16 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.
However, in case the stand-by state of sequence mode (step 0) effective only for AC-INT, ACDC-INT
and DC-INT and when the waveform is sine wave or DC. Remote sensing cannot be set to either ON
or FB unless either AC voltage or DC voltage setting is 0 V for ACDC-INT. Also, if the Remote
sensing is ON, remote sensing is turned OFF once when you change ACDC mode from AC mode of
DC mode even in stand-by state. Turn ON it again when you need.
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
