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.
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.
