Yea! I'm glad you figured out your problem.
TY, I'm not sure I figured it out, but my solution is working for whatever reason so I will not look a gift horse in the mouth...lol
It is nerve wracking. It's suprising how innaccurate these accurate thermometers are.Nice to hear that this one has worked for you! I almost ordered it, but was unsure. I ended up ordering a Brinsea Spot Check, going on their reputation and a couple other folks' recommendations. Same price as that one, but does NOT read humidity. Ugh!I have found the Spot Check to be very accurate. I've bought enough thermometers and hygrometers to stock my own store now! Because I agree, its all so nerve racking, you want a dependable one. But good golly, you would think it would be easier to find one that actually works and works right!
