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
CONF:RES AUTO
or
CONF:RES 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
µ
s. In order to specify an
aperture time of 10
µ
s, you must select a fixed range.

selects the temperature function. All measurements are returned in degrees celsius.
The following transducers can be measurements using the multimeter:
Thermocouples
Thermistors (2-wire or 4-wire measurement)
RTDs (2-wire or 4-wire measurement)
Two-wire temperature measurements can only be made using the scanning
multimeter (a channel list is required).
