I have a night and day digital meter. When I look at it the number is flashing on and off 74319.68, which is 7 time my normal day reading. If I press the button I get 02.06 and it quickly flashes back to the the first number. This is not a reading and its too quick to take a picture. If I press the button a few times I do get a reading that looks like my night time reading of 54602, but again quickly flashes back to the first number. Neither show a small T1 or T2 to indicate which is which. Last time I did it it was really easy and I could get both numbers and take photos of them. Is my meter broken?
