1)When the manufacture’s certificate M (calibration certificate) has to be ordered for transmitters with diaphragm seals, it is recommended only to order this certificate exclusively with the diaphragm seals. The measuring accuracy of the total combination is certified here.

2)Whe the acceptance test certificate 3.1 for transmitters with direct-con- nected diaphragm seals is ordered, this certificate must also be ordered with the corresponding seals.

3)Not suitable for connection of remote seal
