10.15 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.
Effective only for AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA and when the waveform
is sine wave or DC. 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
activated unless either AC voltage or DC voltage setting is 0 V for ACDC-INT. Also, 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.

10.16 AGC
When the AGC (Automatic Gain Control) is on, the detection point voltage is always measured,
and the output voltage is continuously corrected so that its effective value is equal to the output
voltage setting value. The fluctuation of the detection point voltage can be suppressed even when
the load is fluctuated. The detection point can be switched between the sensing input terminal
(remote sensing on) and the output terminal (remote sensing off).
Effective only for AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA and when the waveform
is sine wave or DC. It is turned off when the Sequence or Simulation is selected. It cannot be
selected when the Autocal is set to on.
All models
Response time Within 100 ms (typ.)
(DC/50 Hz/60 Hz, at the rated output voltage)
Operation range The output voltage setting is 8 V or higher
Calibration
range
Within 10 % (difference between the output voltage and measured value)
The output voltage should be within the allowed voltage setting range of the
product.
Accuracy
Within 0.5 V / 1.0 V
(in the case of DC or 40 Hz to 550 Hz, 50 V or higher output voltage, resistance
load, the output current is the maximum current or less)
