Multimeter Command Reference 93Chapter 3
:VOLTage:AC
CONFigure:VOLTage:AC [<range>|MIN|MAX|DEF|AUTO
[,<
resolution>|MIN|MAX|DEF]] selects the AC-coupled RMS voltage function and
allows you to specify the range and resolution.
Parameters
Comments • To select a standard measurement range, specify range as the input signal’s
maximum expected voltage. The multimeter then selects the correct range that
will accept the input.
• The AUTO or DEFault option for the range parameter enables autorange. The
DEFault option for resolution defaults the integration time to 10 PLC.
• The MIN and MAX parameters select the minimum or maximum values for
range:
For range:
MIN = 0.1V; MAX = 300V.
For resolution: See Table 3-4 on page 71 for valid resolution choices for
each range.
• To select autorange, specify AUTO or DEF for range or do not specify a value
for the range and resolution parameters. In the autorange mode, the multimeter
samples the input signal before each measurement and selects the appropriate
range.
• To specify a MIN or MAX resolution while autoranging, you must specify
AUTO or DEFault for range; CONF:VOLT:AC DEF,MIN or
CONF:VOLT:AC DEF,MAX or CONF:VOLT:AC AUTO,MIN or
CONF:VOLT:AC AUTO,MAX (you cannot omit the range parameter). This
prevents the
MIN or MAX resolution from being interpreted as a range setting.
