It has been cold here the last few days. I came down this morning and took my BG as usual. A strange symbol showed up on my meter. I didn't recognize so I looked it up. The symbol was a thermometer and indicated that the meter and/or the strips were not within the correct temperature (50 - 104 F). I had not seen that before. My meter is a Re-lion Prime.
Do any of you have experience with this? I have moved the meter from the floor to the top of the radiator. I hope this helps.
