SIL_9_2011_MAS-100 NT Sampling head selection
We occasionally observe on customer instruments that the sampling head selected does not match the supplied head. Using a different sampling head then selected will lead to a deviation in sample volume.

SIL_3_2011_MAS-100 RCT Battery Problem

empty. This Service Information Letter explains the technical background of this effect and how it can be solved.
SIL_1_2011_MAS-100 CG® Ex Adjustment
Up to now the precision of the MAS-100 CG® Ex mass flow was specified with a symmetrical
tolerance band of +/- 5%.
The result interpretation of most of our customers however is asymmetric: a negative deviation (too little air sampled) is considered worse than a positive one (too much air sampled).
MBV AG decided to bring the adjustment limits in line with the result interpretation: the specification of the instrument precision will change to +10 / -0%.
