[SENSe:]CURRent:{AC|DC}:RANGe {<
range
>|MIN|MAX|DEF}
[SENSe:]CURRent:{AC|DC}:RANGe? [{MIN|MAX|DEF}]
Selects a fixed measurement range for AC or DC current measurements on the 3 A terminals. For DMMs
with a 10 A range, you cannot select the 10 A range with this command; instead, use
or
.
This parameter setting is not shared between AC and DC measurements. The parameters are independent
for AC and DC measurements.
On the 34461A, 34465A, or 34470A, use the
[SENSe:]CURRent:{AC|DC}:TERMinals
command to spe-
cify which current terminals to use for the measurement.
Parameter
Typical Return
<
range
> : {100 µA|1 mA|10 mA|100 mA|1 A|3 A}. Default: AUTO (autorange).
The 34465A/70A have additional DC current ranges of 1 µA and 10 µA.
+1.00000000E-01
Configure AC current measurements using the 1 A range. Make and read two measurements:
CONF:CURR:AC
CURR:AC:RANG 1
SAMP:COUN 2
READ?
Typical Response: +1.0400,+1.0400
l
Selecting a fixed range ([SENSe:]<
function
>:RANGe) disables autoranging.
l
If the input signal is greater than can be measured on the specified manual range, the instrument dis-
plays the word
Overload
on front panel and returns "9.9E37" from the remote interface.
l
Unlike CONFigure and MEASure?, this command does not support the 10 A range. Selecting the 10 A
terminal with
[SENSe:]CURRent:{AC|DC}:TERMinals
forces the specified type of current meas-
urements to use the 10 A range, but it does not affect the values of
or
[SENSe:]CURRent:{AC|DC}:RANGe:AUTO
l
Changing the value of this parameter always changes the measurement resolution. The number of
PLCs (NPLC) stays fixed, and this results in a change of resolution in terms of the units of the meas-
urement. For example, if you have a measurement with 1 µA resolution on the 100 mA range, chan-
ging to the 1 A range results in a resolution of 10 µA.
l
This parameter is set to its default value after a Factory Reset (
) or Instrument Preset
(
).
