USB-2408-2AO


Question

Posted

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?

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.

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.
