VT1422A Command Reference 353 Chapter 7
[SENSe]
[SENSe:]FUNCtion:TEMPerature:POST
[SENSe:]FUNCtion:TEMPerature:POST TC,<sub_type>,[<range>,]
(@<ch_list>)
links VT1529B channels to a post-processing temperature EU
conversion based on the sensor specified in <type> and <sub_type>. Note: Do not
include the thermocouple reference temperature or thermistor excitation channels in
this command (for that, use the SENS:REF:POST <type>,<sub_type>,<range>,
(@<exc_ch>),(@<thr_ch>) command).
This command is valid only on the VT1529B and is available with VXIplug&play
driver revision A.01.09 or later (revision A.01.06 or later of hpe1422_32.dll).
Parameters
Comments •
The VT1422A has five ranges: 0.0625 V dc, 0.25 V dc, 1 V dc, 4 V dc, and
16 V dc. To select a range, simply specify the range value (for example, 4 selects
the 4 V dc range). If a value is specified that is larger than one of the first four
ranges, the VT1422A selects the next higher range (for example, 4.1 selects the
16 V dc range). Specifying a value larger than 16 generates an error. Specifying
0 selects the lowest range (0.0625 V dc). Specifying AUTO selects auto range.
The default range (no range parameter specified) is auto range.
•
The VT1529B has a fixed gain of 32. Keep this in mind when <range> is set.
