[SENSe:]CURRent:{AC|DC}:RANGe:AUTO {OFF|ON|ONCE}
[SENSe:]CURRent:{AC|DC}:RANGe:AUTO?
Disables or enables autoranging for AC or DC current measurements. Autoranging is convenient 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 not shared between AC and DCmeasurements. The parameters are independent for AC
and DCmeasurements.
On the 34461A, use the [SENSe:]CURRent:{AC|DC}:TERMinals command to specify which current
terminals to use for the measurement.
Parameter Typical Return
{ON|1|OFF|0}, default ON 0(OFF)or1(ON)
Configure AC current measurements and perform an immediate autorange. Make and read two measurements:
CONF:CURR:AC
CURR:AC:RANG:AUTO ONCE
SAMP:COUN 2
READ?
Typical Response: +1.04530000E-01,+1.04570000E-01
l Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of range.
l With autoranging enabled, the instrument selects the range based on the input signal.
l Selecting a fixed range ([SENSe:]<function>:RANGe) disables autoranging.
l Selecting the 10 A terminal with [SENSe:]CURRent:{AC|DC}:TERMinals forces the specified type of current
measurements to use the 10 A range, but it does not affect the values of [SENSe:]CURRent:{AC|DC}:RANGe or
[SENSe:]CURRent:{AC|DC}:RANGe:AUTO.
l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset (SYSTem:PRESet).
