• The MIN and MAX parameters select the minimum or maximum values for range
and resolution:
For range:
MIN = 0.0795 V; MAX = 300 V.
For resolution:
MIN selects the best resolution (the smallest value from Table 5-1) for
the selected range.
MAX selects the worst resolution (the largest value from Table 5-1)
for the selected range.
• The channel list is of the form (@ccnn), (@ccnn,ccnn), or (@ccnn:ccnn), where
cc = card number and nn = channel number (105 is channel 05 of card number 1,
for example).
• To select autorange, specify AUTO (or DEF) for range or do not specify a value
for the parameter. 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:AC? AUTO or MEAS:VOLT:AC? DEF (you cannot omit the range
parameter). This prevents the
MIN or MAX resolution from being interpreted as a
range setting.
• The fastest aperture time available when autoranging is 100 µs. In order to specify an
aperture time of 10 µs, you must select a fixed range.
Example Making AC Voltage Measurements
MEAS:VOLT:AC? 0.54,MAX,(@100) !Function: AC volts;
range selected: 0.63 V;
MAX resolution: 61.035

:VOLTage[:DC]?
MEASure:VOLTage[:DC]? [<range>[,<resolution>]] [,<channel_list>] selects the
DC voltage function and allows you to specify the range and resolution. If you
specify a channel list, those multiplexer channels are scanned.
For a complete listing of range and resolution values available, see
Table 5-1 on page 120.
