6. component description
Test stand housing (A)
Thanks to its ergonomic design, the test stand
can be operated fatigue
-
free even during con-
tinuous operation. Operation in computer mo-
de is via PC keyboard and mouse or manually
via the optionally available front panel.
Front panel (B) (optional)
The front panel contains the control buttons
and a multi
-
function LCD display showing print
and system information.
The following abbreviation is used:
LP = Low pressure (
-
50...+50 mbar)
MP = medium pressure (0...25 bar)
Multifunction probe (C)
The test head is a fixed head that can be infla-
ted by an electric pump so that full face masks
of any make can be sealed without problems.
A measuring point is installed in the test head
which measures the internal pressure in the
mask or lung automat.
Medium pressure device connections (D, E)
Plug nipple for connecting the medium pres-
sure line of the compressed air breathing ap-
paratus pressure regulator to be tested.
Quick coupling for connecting the medium
pressure line of the regulator to be tested.
CPS test connection and system vent (F)
Quick coupling for filling CPS. For all other test
procedures, the coupling must be connected
to the supplied plug
-
in nipple/silencer for sys-
tem venting.
Interface (H)
The USB interface for data transfer to a PC is
located on the left side of the housing
(LabModul 240 MT has no function with the
manual device).
Vacuum pump
With the built
-
in vacuum pump, the required air
currents are generated and the probe is infla-
ted or deflated. The desired air flow rate can
be set in the software from 2...12 l/min.
Processor
The built
-
in microprocessor takes over the
control and signal conversion.
