What is the Measurement Temperature Range for NI-9212 for Thermocouple Type K?

Issue Details

• What is the temperature range for thermocouple type K when using NI-9212. In the specification page, it only states "Works over temperature ranges defined by NIST (J, K, T, E, N, B, R, and S thermocouple types)".
• When I was trying to set the Max Value (°C) in the sample VI provided by NI Example Finder, I get the following error:

Error -200077 occurred at Property Node DAQmx Timing (arg 1) in Thermocouple - Continuous Input.vi

Possible reason(s):

Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.

The error is shown in the following dialog box.

Solution

The National Institute of Standards and Technology (NIST) had established standard temperature ranges for various types of thermocouples to ensure accuracy, reliability and consistency in temperature measurements. Commonly, the standard temperature range for type K thermocouples is from -200°C to 1250°C. However, for NI-9212, the DAQmx driver is able to measure temperature from -270°C to 1372°C for type K thermocouple. Setting the temperature either lower and/or higher than the temperature range supported by the device driver will cause error -200077. Make sure to set the temperature within the supported range to prevent the error from appearing.
