WARNING
Improper assembly of manifolds
Improper assembly of manifolds to traditional flange can damage the SuperModule
Platform.
For safe assembly of manifold to traditional flange, bolts must break black plane of flange
web (i.e., bolt hole) but must not contact module housing.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users' equipment. This could be intentional or unintentional and
needs to be protected against.
Physical security is an important part of any security program and fundamental to
protecting your system. Restrict physical access by unauthorized personnel to protect end
users' assets. This is true for all systems used within the facility.

Recommended calibration tasks

CAUTION
Absolute pressure transmitters are calibrated at the factory. Trimming adjusts the position
of the factory characterization curve. It is possible to degrade performance of the
transmitter if any trim is done improperly or with inaccurate equipment.

Procedure
1. Perform sensor zero/lower trim: Compensate for mounting pressure effects
2. Set/check basic configuration parameters.
