I am getting strange readings from my K-type thermocouples. I discovered this issue when I was checking for accuracy. I touch the thermocouple and the temperature drops to 75Â°F (I used the forumla (X*1.8)+32 in the scaling box) and does not change until I let go and then it reads 96Â°F.
I then noticed that when I touch and hold a different one of my 6 thermocouples, it reads 110Â°F and each of the other 5 readings jump 20Â°. I know this sounds funny, but I had 3 other people try the same thing and they all got good readings that did not affect the other thermocouple readings. I washed my hands and dried them thoroughly and no change. I am planning on testing a DC generators heat output, if it is an electric charge that I have that no one else has, would the field or current that the generator produces affect the readings as well?
