THE OVERHAUL
ATEQ carries out the overhaul of your instruments at interesting prices.
The overhaul corresponds to the maintenance of the instrument (checking, cleaning, replacing of used
parts) as part of preventive maintenance.
Preventive maintenance is the best way to guarantee reliability and efficiency. It allows the
maintenance of a group of instruments in good operational order and prevent eventual break-downs.
MAINTENANCE KITS
The ATEQ After Sales Service proposes, two kits destined for the preventive maintenance of the
pneumatic circuits of instruments.
CALIBRATION
This may be carried out on site or in our offices.
ATEQ is attached to the COFRAC and delivers a certificate following a calibration.
TRAINING COURSES
In the framework of partnership with our customers, ATEQ offers two types of training in order to
optimise the usage and knowledge of our instruments. They are aimed at different levels of technician:
•method / control training,
•maintenance / upkeep training.
A TARGETED TECHNICAL DOCUMENTATION
A number of technical documents are at your disposal to allow you to intervene rapidly in the event
minor breakdowns:
•problem sheets describing and offering solutions to the main pneumatic and electronic
problems,
•several maintenance manuals.
A QUALITY GUARANTEE
The instruments are guaranteed for parts and labour in our offices:
•2 years for leak detection equipment,
•1 year for electrical tests to norms instruments,
•1 year for the accessories.
Our After Sales Service is capable of rapidly answering all your needs and queries.
ATEQ recommends
to made realise by its departments
a revision and a calibration of the instruments
every year

PREAMBLE
1. DEFINITION OF THE ATEQ F CLASS
The ATEQ F CLASS are compact air/air
leak detectors used to test the air-
tightness of parts on production lines.
They are specially adapted for automatic
and semi-automatic workbenches. The
method used is based on the
measurement of a small variation or drop
in differential pressure between the test
and reference parts, when both are filled
to an identical pressure.

3. THE MAIN TYPES OF MEASUREMENTS
There are three measurement methods:
Direct measurement, indirect measurement and sealed component measurement.
These three methods apply to measurements taken both under pressure and in vacuum
conditions.
The configuration is determined by the application and must be carried out prior to the
use of the instrument.
3.1. DIRECT/PRESSURE DROP MEASUREMENT
After filling the test and reference parts to the required pressure level, the ATEQ F
CLASS measures the differential pressure between the two volumes which are
separated by the equalisation valve.
At the end of a cycle, the ATEQ empties the components via the dump valve.
3.2. INDIRECT/PRESSURE RISE MEASUREMENT
The test part is placed in a sealed bell and the ATEQ F CLASS is pneumatically
connected to the bell. The part is externally pressurised (with up to 20 MPa or 200 bar),
and the bell is lightly pressurised. In the event of a part leakage, the pressure in the bell
will rise. This method allows certain parts to be tested at high pressure levels whilst
avoiding the associated constraints. The ATEQ F CLASS only tests and measures the
pressure in the bell. In the event of a large leak, electronic monitoring of the pressure in
the bell will switch the instrument to safety.

This test is for hermetically
sealed parts, which can not be
filled. They are placed inside a
bell which is pressurised.
The first and the third measurements may be carried out in comparison with a
reference, without reference or in central zero.

Preamble
UM-23100B-U User manual ATEQ F CLASS Page 7/90
4. THE THREE TYPES OF TEST
4.1. TEST WITH REFERENCE
TEST PART
SENSOR REFERENCE
PART
Measurement of a pressure variation
between a test part and a reference part.
The ideal measurement conditions are:
part and reference part identical and
identical ATEQ connections to both parts
(identical lengths, diameters, and type of
pipes). A measurement taken with a
reference part saves time because the
pressure equalisation is more rapid. It is
valid for parts which cannot be deformed
and which mimic thermal and mechanical
effects.
4.2. TEST WITHOUT REFERENCE
TEST PART
SENSOR
CONNECTOR
Measurement of a variation in pressure
between a test part and a sealing
connector on the reference side. A test
without reference is not recommended
unless parts with very small volumes are
being tested. It is preferable always to
have a certain volume on the reference
side.
4.3. TEST WITH CENTRAL ZERO
TEST PART
SENSOR
TEST PART
It is possible to test two parts at the same
time. One part is connected to the test
side and the other to the reference side.
The differential sensor measures the drop
in pressure in one part in relation to the
other. This method may be used when
the number of bad parts is very low
(generally less than 1%). The probability
of having two bad parts at the same time
is very low. This method is also used for
deformable parts and parts with a
constant temperature which is different
from the ambient temperature. The
central zero test offers a considerable
time gain (two parts tested
simultaneously).

5. DIRECT MEASUREMENT, PRESSURISATION

The measurement cycle consists of 5 phases:
1 2 3 4 5
Start Wait time Fill time Stabilization
time
Test
time
Dump
time
Cycle
end
Start cycle start
The wait
time
The time during which the sealing connections are made to the test
parts before the part is filled. The instrument may be fitted with the
optional automatic connector. This valve is controlled for the duration of
the cycle to enable the installation of the expandable joint connectors to
be checked
The fill time
Pressurisation of the test and reference parts. At the end of the fill time,
the ATEQ instrument checks the test pressure. If this is not correct, it
will signal a test pressure fault.
The
stabilization
time
The test and reference parts are completely cut off from the air supply,
but are pressurised to the test pressure level. Pressure and
temperature will then stabilise between the two parts which
communicate and act similarly. If the test pressure is incorrect (a large
leak on one of the volumes) the test pressure will drop rapidly, the
instrument will not move on to the test mode and will indicate a fault.
The test time
The test and reference parts are isolated from each other and the
pressure sensor measures the difference in pressure between them.
The signal is electronically assessed and displayed, the part is then
diagnosed as good or bad.
The dump
time Return of the parts to the atmospheric.
Cycle end
Once the dump has been carried out, the instrument emits a cycle end
signal and the automatic connector valve (optional) is deactivated. This
valve can control one or more expandable connectors from the
beginning to the end of the cycle.
