[SENSe:]FUNCtion:TEMPerature
[SENSe:]FUNCtion:TEMPerature <type>,<sub_type>,[<range>,](@<ch_list>)
links channels to an temperature EU conversion based on the sensor specified in
<type> and <sub_type>. Note: Do not include the thermocouple reference
temperature channels in this command (for that, use the SENS:REF
<type>,<sub_type>,(@<channel>) command).
Parameters
Comments •
Resistance temperature measurements (RTDs and THERmistors) require the use
of Current Source Signal Conditioning Plug-Ons. The following table shows the
Current Source setting that must be used for the following RTDs and Thermistors:
•
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 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.
