[SENSe:]VOLTage:{AC|DC}:RANGe:AUTO {OFF|ON|ONCE}
[SENSe:]VOLTage:{AC|DC}:RANGe:AUTO?
Disables or enables autoranging for AC and DC voltage measurements and for DC ratio measurements.
Autoranging is convenient because it automatically selects the range for each measurement based on the
input signal.
Specifying ONCE performs an immediate autorange and then turns autoranging off.
This parameter setting is not shared between AC and DCmeasurements. The parameters are independent
for AC and DCmeasurements.
The maximum range parameter (MAX) is 1000 V. However, the SAFETY LIMIT on the front
and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform dependent.
A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is safe. Connection
to AC mains power is further limited to CAT II (300 V). See Safety and Regulatory
Information for more information on the safety features and the safe operation of this
instrument.

l Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
range.
l With autoranging enabled, the instrument selects the range based on the input signal.
l
Selecting a fixed range ([SENSe:]<function>:RANGe) disables autoranging.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
(SYSTem:PRESet).
