Known-Type Thermocouple Channel
Configure a known-type thermocouple channel if you have a B-, E-, J-, K-, N-, R-, S-, or T-type thermocouple.
To configure a known-type thermocouple channel, follow these steps:
Select one of the thermocouple sensor options. Click Next.
Enter the units you are using for the measurement.
Enter the minimum and maximum temperature measurement values in the Range selection boxes. MAX automatically calculates the voltage range from the temperature range you specified in your physical quantity. Then it uses this voltage range to set the DAQ hardware for measuring your thermocouple. MAX uses built-in thermocouple formulas to convert thermocouple types B, E, J, K, N, R, S, and T.
Click the checkbox to display values in scientific notation. Click Next.
Confirm the sensor output range. Click Next.

RTD Channel
Configure a resistive temperature device (RTD) channel if you have Platinum RTD types ITS-90, American, DIN 43760, and IEC 60751 type sensors.
To configure an RTD channel, follow these steps:
Select one of the RTD sensor options. An RTD sensor converts a temperature measurement to a resistance measurement, which a DAQ device can then measure directly. MAX then uses built-in Platinum RTD formulas to convert each RTD type from resistance to temperature.
To use your own custom RTD conversion for Platinum or non-Platinum RTDs, select Resistance (an RTD is a resistive device) as your sensor type.
Click Next.
Enter the units you are using for the measurement.
Enter the minimum and maximum temperature measurement values in the Range selection boxes. MAX converts the temperature measured at the sensor output to your physical quantity.
