The listed deviations are only exemplary, and can vary by up to ± 0.2 vpm. The actual
deviation must be determined in individual cases, and the error can be eliminated by
appropriate correction of cross-interference (see operating function 83).

2.6 Communication
2.6.1 General information
All gas analyzers of Series 6 such as ULTRAMAT 6, OXYMAT 6/61/64, CALOMAT 6/62,
FIDAMAT 6 as well as ULTRAMAT 23 offer the following communication possibilities:
● ELAN interface
● SIPROM GA (Version 1.9.14 and higher)
● PROFIBUS DP/PA
● Generic communications interface (only ULTRAMAT 6E, OXYMAT/ULTRAMAT 6E,
OXYMAT 61, OXYMAT 6).
