The way your my unity is typed may vary from the way it is stored by Number Verifier. Or this unit is not stored at all there. That could be the problem.

Oh... Well, that could be it, yes. Do you know how I could access the list of units Number Verifier has in store?

I can't find it, be it for the regular Trados QA or the Number Verifier Plugin.

Sorry, I hoped to find such a setting, but it is indeed not there. What you could only do is adding a regex to ignore segments with this particular measurement unit. The regex would simply be literally that unit, nothing more. I suppose that could help minimize such false positives.

However, otoh there always will be false positives, as no machine is able to think like a human being and to differ between numbers, chapters, errors in source and so on...

Thank you! I just added "µ" as a the regular expression and told it to replace by "unbreakable space-µ". I hope it'll work!

Yes, you're right there will always be false positives: but these small tips & tricks like you've just given might help lower their numbers
