4.1 SENSOR INPUT TYPES
THERMOCOUPLE: Most standard types and all special types using customer
defined tables and polynomials.
RTD (2, 3 or 4 wire configuration): Platinum (e.g. Pt-100), Nickel, Copper, and
other RTDs (includes Callander-Van-Dusen and custom sensor linearization with
user defined tables and polynomials up to 10
