MEASure[:VOLTage]:{AC|DC}? [{<
range
>|AUTO|MIN|MAX|DEF} [, {<
resolution
>|MIN|MAX|DEF}]]
Sets all measurement parameters and trigger parameters to their
for AC or DC voltage meas-
urements and immediately triggers a measurement. The results are sent directly to the instrument's out-
put 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
for more information on the safety features and the safe operation of this
instrument.

You can let autoranging select the measurement range, or you can manually select a fixed range.
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).
l
Autoranging (AUTO or DEFault), will generate an error if you specify a <
resolution
> because the instru-
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.
l
Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
range.

If the input signal is greater than can be measured on the specified manual range, the instrument dis-
