Multimeter Command Reference 109Chapter 3
[:VOLTage[:DC]]?
MEASure[:VOLTage[:DC]]? [<range>|MIN|MAX|DEF|AUTO
[,<
resolution>|MIN|MAX|DEF]] selects the DC 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 to
accept the input.
• The AUTO or DEFault option for the range parameter enables autorange.
The
DEF option for the resolution parameter defaults the integration time to
10 PLC.
• The MIN and MAX parameters select the minimum or maximum values for
range and resolution:
For range:
MIN = 100mV; MAX = 300V.
For resolution:
MIN selects the best resolution (the smallest value) for the
selected range.
MAX selects the worst resolution (the largest value) for the
selected range. See Table 3-1 on page 70 for valid resolution choices for
each range.
• To select autorange, specify DEFault 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
MEAS:VOLT:DC? DEF (you cannot omit the range parameter). This prevents
the MIN or MAX resolution from being interpreted as a range setting and the
resulting command becomes
MEAS:VOLT:DC? DEF,MIN or
MEAS:VOLT:DC? DEF,MAX.
