Test and Measurement Forum

According to the manual, if I set the thermocouple type for TC-08 to "X", the output will be reported as millivolts. Is it safe to assume that the cold junction temperature does not affect the measurement results, but I can still poll this parameter to monitor the internal temperature of the unit? Thanks!

Hi,
You must have a very old version of PicoLog or Manual!
To set a voltage input for the TC-08 you select "mV" and the cold junction is not applied to that channel. You get a straight reading of mV. The cold junction temperature can still be read in the usual way.

Sorry, I did not clarify that I was using the TC-08 API - I write my own programs to communicate with the logger. I was quoting from the description of the function "usb_tc08_set_channel". I hope that using the "X" parameter for "tc_type" is still valid.

Thanks,

Ah! I understand. Yes, you can still use the "X" parameter when using the API. The cold junction reading is still valid as you might be using it for other channels.
