[SENSe:]{FREQuency|PERiod}:VOLTage:RANGe:AUTO {OFF|ON|ONCE}
[SENSe:]{FREQuency|PERiod}:VOLTage:RANGe:AUTO?
Disables or enables voltage autoranging for frequency and period measurements. Autoranging is con-
venient 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 is shared between frequency and period measurements. Setting or querying the parameter
with the FREQuency version of this command is identical to setting or querying it with the PERiod version.
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

The input signal for frequency or period measurements has an AC voltage component. Use this com-
l
mand to disable or enable voltage autoranging or use
voltage autoranging by default. Use
voltage range for frequency and period measurements.
Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
l
range.
Selecting a fixed range ([SENSe:]<function>:RANGe) disables autoranging.

This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset
