tcairns Posted February 14 Share Posted February 14 What is the Accuracy formula for the thermocouple for the USB-2408-2AO? 1% of reading + 1°C? If I was to measure -100°C what would my tolerance be for type J thermocouple? Link to comment Share on other sites More sharing options...
0 Fausto Posted February 14 Share Posted February 14 Hello @tcairns. An accuracy formula nor a table of the full temperature range are not available. At -100°C, a typical accuracy error of +/-1% would be reasonable. You will also need to add the error of your thermocouple as well. The thermocouple vendor typically provides that information.

0 tcairns Posted February 16 Author Share Posted February 16 Could you use the forecast function in excel to get the tolerance values for each temperature range? Link to comment Share on other sites More sharing options...
0 Fausto Posted February 16 Share Posted February 16 It is nonlinear. If your tests will always be at a given temperature, with the same USB-2408-2AO module, and the same thermocouples, then you can measure and create your own custom table.
