Temperature measurements using resistance type sensors involve all the same
considerations as resistance measurements discussed in the previous section.
See the discussion of Figure 3-2 in "Linking Resistance Measurements".

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:

sub_type values of 2250, 5000, and 10000 refer to thermistors that match
the Omega 44000 series temperature response curve. These 44000 series
thermistors have been selected to match the curve within 0.1 or 0.2°C.
