10.17 Autocal (Output Voltage Compensation)
When the Autocal (Automatic Calibration) 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 ratio (correction factor) of the detection point voltage to the output
voltage setting value is used until the Autocal or the power is turned off. Therefore, the detection
point voltage is not necessarily maintained if the load changes while the Autocal is on. The
detection point can be switched between the sensing input terminal (remote sensing on) and the
output terminal (remote sensing off).
Unlike the AGC, it cannot follow a load fluctuation because it does not keep track of the voltage.
On the other hand, when the load is stable, it has a merit of short response time on changing the
output voltage setting.
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 AGC is set to on.
