CoaguChek INRange

[Pompeyboysf1]

hi all. I have a CoaguChek INRange and I have a batch of test strips and the machine keeps coming up test strip error (M-24). The strips go out of date at the end of September so should be ok but it says the meter does not recognize test strip. I have tried a reboot. Anybody have any ideas please? 😃

I don’t know if this is the issue, but there’s a little ‘chip’ that slots into the side of the machine, with each different batch of testing strips. If it’s not the relevant one, the strips won’t register in the machine. That is the extent of my technical knowledge on the subject! 😂
