ON
<ch_list>
Channel
List
One or more channels (only for channel 21
to channel 24 of MC3324), the rules are as
follows:
(@121): channel 21 on the module in Slot1;
(@121:123): channel 21 through 23 on the
module in Slot1;
(@121:123,324): channel 21 through 23 on
the module in Slot1 and channel 24 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:]CURRent:AC:RANGe and [SENSe:]CURRent[:DC]:RANGe commands).
 The
CONFigure:CURRent:AC (CONFigure:CURRent[:DC]) or MEASure:CURR:AC?
(
MEASure:CURR[: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 CURR:AC:RANG:AUTO 1, (@321:322)
CURR:AC:RANG:AUTO? (@321:322,324)
The query returns 1,1,0.
You can replace AC with DC to disable or enable the autoranging of the DCI measurements
on the specified channels.
