MEASure:CURRent:{AC|DC}? [{<range>|AUTO|MIN|MAX|DEF} [, {<resolution>|MIN|MAX|DEF}]]
Sets all measurement parameters and trigger parameters to their
measurements and immediately triggers a measurement. The results are sent directly to the instrument's
output buffer.
<range>: {100 µA|1 mA|10 mA|100 mA|1 A|3 A|10 A}. Default: AUTO
(autorange).
<resolution> (AC): optional and ignored; fixed at 6½ digits.
<resolution> (DC): See
NPLC.
The default is equivalent to 10 PLC.
Specify <resolution> in the measurement's units (V, A, Hz, Ω, and so
on).
Configure AC current measurements using the 1 A range. Then make and read one measurement:
MEAS:CURR:AC? 1
Typical Response: +8.54430000E-01
You can let autoranging select the measurement range, or you can manually select a fixed range.
l
Autoranging conveniently selects the range for each measurement based on the input signal. For fast-
est measurements, use manual ranging (autoranging may require additional time for range selection).
Autoranging (AUTO or DEFault), will generate an error if you specify a <resolution> because the instru-
l
ment cannot accurately resolve the integration time (especially if the input continuously changes). If
your application requires autoranging, specify DEFault for the <resolution> or omit the <resolution>
altogether.
Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
l
range.
If the input signal is greater than can be measured on the specified manual range, the instrument dis-
l
plays the word Overload on front panel and returns "9.9E37" from the remote interface.
