Chapter 4
NOTES
1. 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:
2. The
<sub_type>
parameter 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.
