Although the instructions for this thermometer were probably written by a five year old, after about 45 minutes of playing around, I was able to figure out through trial and error how to set this thing up. After doing that, I was able to test several thermoelectric generators with great accuracy. I did not use the bead sensors included in the kit but bought 4 sensors in a metal case. They work much, much better! The SIM card is already formatted, so you don't have to do anything. Great meter, love it but have to rewrite my own instructions so I don't forget and get back to using it.
