Ah sorry, yes you did asked about "attendu" - I was focused on the weighing! Glad you got it sorted :)

@ all Hello

I screwed up this question as I completely forgot to say that the client's TM had "reverse weighing" and I was more stuck on "attendu"
The client said that "attendu" here was indeed "expected"
Sorry about that

Hi SafeTex,

Differential weighing looks good, however I also came across some content that indicated that the term covers two principles: transposition (Gauss) weighing and substitution (Borda) weighing.

I don't know how authoritative this is but seeing as it's talking about metrology, it may help:

In your case, "transposition weighing" may work if you need a term more specific than differential weighing.

This French metrology website also gives a bit more information about this "pesée par inversion":

differential weighing looks right.

Care to put it as your answer?

Back-weighing is a term used in laboratories - could it be this? Also differential weighing, or weighing by difference
