Hello, Version is 5.21.2.

I have just installed the latest software on my system. XP. It starts recording ok but causes the system to crash intermittently..

I am using a PICO tC-08 Serial with a usb converter

Thanks for that. The polarity did the trick. I did not meen 2 thermocouples twisted together but just the type K cable ends twisted together to form 1 thermocouple not ideal I know but its ok for getting the kit set up and operating..


Cheers
