Syntax [SENSe:]VOLTage:AC:RANGe:AUTO <state>[,(@<ch_list>)]
[SENSe:]VOLTage:AC:RANGe:AUTO? [(@<ch_list>)]

<ch_list>
Channel
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101): channel 01 on the module in
Slot1;
(@101:103): channel 01 through 03 on the
module in Slot1;
(@101:103,301): channel 01 through 03
on the module in Slot1 and channel 01 on
the module in Slot3.
If the parameter is
omitted, this
command will be
applied to the
whole scan list.
Explanation  Autoranging rule: for signals under test that is between 10%*Range and
110%*Range, the instrument automatically selects Range as the current range.
 Selecting a specifc range for the specified channel will disable the autoranging (send
the [SENSe:]VOLTage:AC:RANGe
or [SENSe:]VOLTage[:DC]:RANGe command).
 The
CONFigure:VOLTage:AC (CONFigure:VOLTage[:DC]) or MEASure:VOLTage:AC?
(
MEASure:VOLTage[:DC]?) command automatically enables the autoranging if the first
parameter is AUTO, DEF or omitted.
 The instrument selects autoranging after a Factory Reset (send the
*RST command).
An Instrument Preset (send the
SYSTem:PRESet command) or Card Reset (send the
SYSTem:CPON command) does not affect the current range setting.
Return
Format
The query returns 0 (OFF) or 1 (ON). Multiple return values are separated by commas.
Example
VOLT:AC:RANG:AUTO OFF,(@201:203)
VOLT:AC:RANG:AUTO? (@201:203)
The query returns 0,0,0.
You can replace AC with DC to enable or disable the autoranging of the DCV measurements
on the specified channels.
