Autocal - NF DP060LM Instruction Manual

11.18 Autocal

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). When setting remote sensing to FB, AGC cannot be set, see 11.16.
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.
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. Autocal cannot be activated unless either AC
voltage or DC voltage setting is 0 V for ACDC-INT. Also, Autocal 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.

The output voltage should be within the allowed voltage setting range of the
product.
