Now to the question.

I checked this myself, and it was indeed fluctuating between -19 and +2 (mostly -)

The engineer said they only ever check the u/s signal which should be between 40-60, the lower the better. It was 40 ish.

The question is, which one of them was correct, and what would cause the fluctuating d/s signal?

Thanks in advance for any replies.
