Term ’FS’:
'FS' is the Full Scale of the positive side range. E.g. for ±200 mbar module, the Full Scale is 200 mbar.

1)
Uncertainty includes reference standard uncertainty, hysteresis, non-linearity, repeatability and typical long term
stability for mentioned period (k=2).
2)
Every internal/external pressure module’s range may be displayed also in absolute pressure if the Barometric
Module (B) is installed.
All standard accuracy external pressure modules are also compatible with Beamex MC5 and MC5P Calibrators
(firmware version 1.90 and onwards).
