MEASure[:VOLTage]:{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.
The maximum range parameter (MAX) is 1000 V. However, the SAFETY LIMIT on the
front and rear HI/LO input terminals is 750 VAC (rms). The rms voltage is waveform
dependent. A sine wave is limited to 750 VAC (rms), but a 1000 Vpk square wave is
safe. Connection to AC mains power is further limited to CAT II (300 V). See
and Regulatory Information
operation of this instrument.
<range>: 100 mV, 1 V, 10 V, 100 V, 1000 V, AUTO (default) or DEFault
<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 DC voltage measurements using the 10 V range with 1 mV resolution.Then make and read one
measurement:

Typical Response:+8.54530000E+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.
