4.16. Connecting Thermocouples
Thermocouples connect to the C or D channels as shown below.
The key settings for thermocouples are:
 Measurement Type: Analog
 Analog type: Diff C, D or E.
 Input Range: 39mV with Bias
 Equation: 24716*X+Terminal_temp {K type thermocouple, -8C to 64C}
For more accurate results, here are some other K-Type Equations:
Linear delta T range of ± 20°C. Approximation error is ±0.20°C.
Temp (°C) = 25.346 * X*1000 – 0.1114 + Terminal_temp
Linear delta T range of ± 40°C. Approximation error is ±0.83°C.
Temp (°C) = 25.419 * X*1000 – 0.3847 + Terminal_temp
