The device is delivered together with brief instructions (Leporello) and a CD-ROM containing detailed documentation.

1)For oxygen application, add Order code E10.

2)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.

3)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.

4)Without cable gland, with blanking plug.

5)With enclosed cable gland EEx ia and blanking plug.

6)Cannot be used together with the following types of protection: "Explosion-proof" and "Intrinsic safety and explosion-proof"
