Delivery was good. But at trial runs, I was not able to get a good measurement out of a 28x1mm pipe (heating system). Is there a trick how to place the transducers on the pipe? i wasn't able to get a stable signal. And what means "N" and "W" positiobing. It's not described in the manual. At the moment it isn't usable for me. If it works, i would give 5 stars, till now its just 2
I did not received for 3 months because of pandemic, seller resent it by DHL and it arrived in one week! Thanks.
