[SENSe:]CURRent:AC:RANGe
[SENSe:]CURRent[:DC]:RANGe
Syntax [SENSe:]CURRent:AC:RANGe {<range>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]CURRent:AC:RANGe? [{(@<ch_list>)|MIN|MAX}]
[SENSe:]CURRent[:DC]:RANGe:AUTO <state>[,(@<ch_list>)]
[SENSe:]CURRent[:DC]:RANGe:AUTO? [(@<ch_list>)]
Description Set or query the measurement range of the ACI and DCI measurements on the specified
channels.
Parameters
Name
Type
Range
Default
<range> Numeric
Any numeric value between MIN and MAX.
The final range is decided by the “
Principle
of setting with greater value
”.
The standard values of the range:
{200μA|2mA|20mA|200mA|1A}
Wherein: MIN=200μA, MAX=1A,
DEF=AUTO.
AUTO
<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  Selecting a specifc range for the specified channel will disable the autoranging (refer to
the
[SENSe:]CURRent:AC:RANGe:AUTO and [SENSe:]CURRent[:DC]:RANGe:AUTO
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.
 If the input signal is greater than can be measured on the selected range, the
instrument gives an overload indication: "OVERLOAD" from the front panel or
"±9.9E+37" from the remote interface.
 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 the range of the specified channel in scientific notation. Multiple return
values are separated by commas.
Example CURR:AC:RANG 0.2,(@222,223)
CURR:AC:RANG? (@222,223)
The query returns +2.00000000E-01,+2.00000000E-01.
You can replace AC with DC to select the measurement range of the DCI measurements on
the specified channels.
