In 2011 MBV AG initiated an upgrade program for the MAS-100 NT family as a preventive warranty action to change the initial blower motor to a stronger one. For more information refer to SIL_4_2011_ MAS-100 NT Upgrade_Rev1.

One year later MBV launched as part of the continuous improvement the HW6 mainboard which is needed together with the upgrade kit. For more information refer to SIL_5_2012_ MAS-100 NT-Ex New Mainboard (HW Rev. 6)

In January 2013 MBV has terminated the free of charge warranty program but the upgrade kit is still available as spare part.

This SIL explaines the todays approach repairing the different MAS-100 NT instrument configurations.

SIL_9_2013_ Interpretation of calibration results

The final accepted / not accepted result on the automated calibration certificate has a hard limit at +/- 2.5%. If the average of the 3 measurements or a single individual measurement is outside this limit (even with the average within the limit) the calibration is interpreted as “not accepted”. 

This is the strictest way to look at it but different interpretation of the results can be equally true. This Service Information Letter explains why.

SIL_8_2013_MAS-100 CG Ex packing

Shipment costs from all over the world to MBV Switzerland for the yearly calibration of the  MAS-100 CG Ex are quite expensive. To optimize the transport and therefore to reduce the shipment cost MBV is launching a special membrane packing.
