The Upper Panel

External Pressure Modules
Internal Pressure Modules
The upper panel has 5 places for the following modules/connec-
tors:
MC5-IS has a connector for External Pressure Modules (EXTs). The
connector is located on the right hand side of the upper panel and
is marked with PX1 in a sticker on the upper panel.
Up to three Internal Pressure Modules may be installed in MC5-IS.
One of them may be an internal barometric module.
The connectors for Internal Pressure modules start from the sec-
ond connector on the left. The possible Barometric Module is al-
ways located as second from right and it measures the barometric
pressure through a connection in the back panel of MC5-IS. Nor-
mally nothing need to connected to the barometric pressure module's
connector.
Internal pressure modules are marked with P1 ... P3.
The recommended pressure medium for all internal pressure mod-
ules is clean air. Clean non-corrosive liquids may optionally be used
in modules with a measuring range of 20 bar/300 psi or more. Avoid
spilling liquid on MC5-IS when connecting/disconnecting pressure
hoses to/from pressure modules.
To avoid damaging the calibrator, use hand tightening only when
connecting the pressure measurement hoses (max. torque 5 Nm,
approx. 3.6 lbf ft). If the use of tools is required to secure the con-
nection (typically pressure modules with a pressure range higher
than 20 bar), apply the counterforce with a spanner on the connec-
tor body's hexagonal part.
The overpressure protection of the internal pressure modules vents
to the back of the calibrator. Remember to be cautious when work-
ing with pressure and pressure modules. See also chapters Safety
on page 25 and Safety Precautions and Warnings on page 26.
