Tried using my checker last night and kept getting this fault. Tried a new battery, a few different cuvettes, even no cuvette, same thing. I can see the light is on inside, maybe the pickup sensor is not working. Some Googling shows I am not the first to have this problem but it doesn't seem crazy common either.
I ordered a new meter already but just wondering if there is anything else I should try, if someone has corrected this problem somehow. The meter is about three years old.
Thanks
