4. Programming
Instruction 11 is used to measure the CR10XTCR. Instruction 11 provides AC
excitation, makes a single ended voltage measurement, and calculates
temperature with a fifth order polynomial. A multiplier of 1.0 and an offset of
0.0 yields temperature in Celsius. For Fahrenheit, use a multiplier of 1.8 and an
offset of 32.
The reference temperature for thermocouples must be in
degrees Celsius. CAUTION
