1. foreword
This operating manual describes the operation
of LabModul 240 series of test instruments.
Labtec test devices are professional tools that
require comprehensive respiratory protection
expertise, e.g. by completing training as a re-
spirator maintenance technician, to ensure
proper operation and correct measurement.
A prerequisite for proper operation of the de-
vice is that the device is operated and used
exclusively in accordance with these operating
instructions. Labtec is not liable for personal
injury or damage to property or consequential
damage of any kind if the device is used in a
manner other than that described in this manu-
al. The same applies to the acceptance of any
warranty and guarantee claims.
Otherwise, the terms of sale and delivery as
well as the warranty and guarantee conditions
of Labtec GmbH apply, which are not exten-
ded in any way by these instructions.
2. safety instructions
Each Labtec test device requires device-
specific instruction by an authorized Labtec
employee or training partner.
The device may only be operated by instructed
and authorized personnel.
The device may only be serviced and repaired
by trained and certified Labtec service techni-
cians. Only original spare parts and accessori-
es must be used.
The device may only be opened by a Labtec
service technician or, if expressly requested,
under instruction by a Labtec employee.
To ensure proper functioning of the device and
thus a correct measurement result, the device
must be serviced at least once a year by a trai-
ned and certified Labtec service technician
and tested and calibrated by him or her using
a Labtec calibration device.
The list of current, certified employees, training
partners and service technicians is updated
daily and is available from Labtec or on the
Labtec homepage.
Labtec devices are partly operated with brea-
thing air in the high pressure range of up to
400bar. Operating a device under high pres-
sure requires the greatest care. Before
connecting and disconnecting a test item / bre-
athing apparatus, the test bench must always
be completely depressurized and air supply
lines, especially the main valve, closed.
The device connection must always be che-
cked. Devices must always be connected
completely correctly. When connecting to the
high pressure device connection, the device
thread must be completely screwed to the in-
ternal thread of the device connection.
Before switching off the test device electrically,
the test bench must first be completely depres-
surized and vented and then all connected de-
vices and any full face masks must be remo-
ved.
Never test dirty demand valves or masks on
the test head. There is a risk of dust particles
getting into the measuring system, which can
impair the function.
When the test stand is started up, the mouth
opening and the instrument connections must
remain open, otherwise self-calibration will be
incorrect and the measurement data will be
incorrect.
The test device must be set up horizontally
and rest well on all support buffers.
Care must be taken to ensure that the measu-
ring nozzle in the mouth opening in the test
head is not clogged. In case of false measu-
ring values in low pressure, the opening can
be cleaned with a 0.2 - 0.35 mm needle.
In case of queries or uncertainties
contact the Labtec customer service!

When setting up the unit, make sure that it is
horizontal and rests well on all support buffers.
Establish power supply
Connect the power supply to a 230 V / 50-60
Hz power source using the supplied power
cable. Switch on the unit at the switch.
Establish connection to the PC (not with MT)
Install the LabNet Profi test software accord-
ing to the installation instructions. Establish the
connection between PC and test bench via
USB cable.
> See separate installation and operating
instructions LabNet Profi
Device connection (breathing mask)
The test head must be completely vented. The
breathing connection of the mask is closed
with a suitable sealing cap. Alternatively,
connect the mask to a suitable demand valve
and then make a device connection (SCBA).
The mask is put on the test head. The inner
mask should rest correctly on the nose of the
probe.
Then tighten the fasteners of the head mask
starting from the bottom. The test head can
now be inflated until a tight fit of the mask is
ensured. If necessary, readjust the mask.
Device connection (SCBA)
For tests in the medium pressure range, dis-
connect the medium pressure line of the
SCBA at the Euro coupling and connect it to
the plug nipple of the medium pressure device
connection and the line of the demand valve to
the EURO quick coupling of the medium pres-
sure device connection.
If the SCBA to be tested does not have a Euro
coupling, a suitable adapter must be used.
Please contact the compressed air breathing
apparatus manufacturer.
The demand valve is inserted into the mouth
opening of the test head using a suitable
adapter.
9. care and maintenance
The test instrument should be protected from
external harmful influences such as water, mo-
isture in the form of steam and dust.
The test head should be cleaned and maintai-
ned regularly. This can significantly increase
the service life of the search unit.
The test head should always be covered with
the enclosed protective hood after the instru-
ment has been used.
> See separate test head care instructions
The test device must be serviced at least an-
nually by a certified Labtec service technician.
The test device is recalibrated and deviations
in the previous test cycle can be excluded.
The maintenance is carried out with a special
calibration device.
The maintenance is confirmed by a calibration
certificate issued directly by Labtec. The main-
tenance may only be carried out by authorized
and trained service technicians.
In order to ensure a cost-effective and timely
maintenance, it is possible to conclude a main-
tenance contract with Labtec.
