specify sense channel list.
TRIG:COUN 3 !Scan channel list 3 times (take 4 readings
per trigger); trigger source is IMMediate by
default.
READ? !Place multimeter in wait-for-trigger state and
make measurements;
send readings to output buffer.
enter statement !Enter readings into computer.
:RESistance
CONFigure:RESistance [<range>[,<resolution>]] , <channel_list>
selects the 2-wire ohms function and allows you to specify the range and resolution.
Two-wire resistance measurements can only be made using the scanning multimeter
(a channel list is required).
For a complete listing of range and resolution values available, see
Table 5-1 on page 120.

Comments • To select a standard measurement range, specify range as the input signal’s
maximum expected resistance. The multimeter then selects the correct range.
• The AUTO and DEFault options for the range parameter have the same effect
(enable autorange). The
DEF option for the resolution parameter defaults the
integration time to 1 PLC.
• The MIN and MAX parameters select the minimum or maximum values for range
and resolution:
For range:
MIN = 232 Ω; MAX = 1048576 Ω
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.
