MY probe is screwed up and doesnt work. worked for about 3 months. it will not calibrate just reads 7 no matter what. was reading 1,3 for a while. there is a bubble in the tip is this probe shot out so soon or is there a trick to fixing it? i have 7.0 and 10.00 to calibrate but doesn't work.

If there is a bubble, you need to get it out of there. Shake it and it should make it rise.
The tip should be filled with liquid and not air.

ok ill try that thanks
