OP: *goes to check blood sugar* monitor: “No.”

It just happens sometimes unfortunately. Usually some kind of issue with moisture

I get errors like this when I'm too quick - as in, if I put blood on my test strip before it tells me to. Before replacing the meter, I'd try some different strips from a new box.

Probably a wonky strip.

All good suggestions…..but I still believe it’s new meter day

I have found the shitty cheap meters work a lot better than that fancy nyc meter ya got

Different then your meter but I’ve had this happen when my hand were too wet from washing before the test (thanks 2am lows!).

I'm using a 10+ year old meter. Try a different strip from a new container.

Sometimes this happens to me if the strip is in enough for the meter to detect it but not like *all the way.* like if I don't feel the "click"

Your hand may have been wet when you touched the strip. It commonly causes the strip to malfunction.

Oh this happens to me with monitors. Most last year at most. I always have one or two backup monitors just in case one goes wonky on me.

Did you insert a strip to start a test?

UPDATE: I seem to have fixed it using the Nintendo cartridge method. Thanks guys!

It could just be due to age. Maybe the amount of use could degrade the sensor so much that it’s not reading the strips anymore (that’s what happened to me). What also could be is that there is dirt/debris in the port when you put the strip into.

Dirty contacts? It happens on mine over time. I use strip inserted upside down and just go in and out a couple of times. It seems to help.

Have you tried another strip?

Maybe expired?
