How Do I Implement Transm it ter-SensorMatching?
Characterize the sensor. Order the X8option for a Calibration Schedule over a customer -
specified temperature range
OR
Order the appropriate V option

How Do I Implement Transm it ter-SensorMatching?
Calibrate the transmitter to the sensor! Change thecurve in the transmitter using Callendar-Van Dusen
constants: R0, a, b, d 275 used to enter constants
AMS to enter constants
The transmitter can be purchased with the Callendar-VanDusen constants already entered: C2 Option
They must have ordered an X8or Voption on their RTD, too!
This curve gives the transmitter the shape of the RealRTD curve and eliminates interchangeability error!
: TheC2 Option is offered with which models?

Error correction profile is programmed into transmitter. Each transmitter has an on-board RTD to measure
ambient temperature.
Based on the reading, transmitter software corrects for
ambient temperature effects.

Computerized test system learns
how transmitter reacts at varying
