2.2.2. 1) Automatic connector A
Used for connection of an automatic pneumatic connector.
2.2.2. 2) Automatic connector B
Used for connection of a second automatic pneumatic connector.
2.2.2. 3) Pneumatic inputs/outputs
These outputs enable parts to be connected
(test, reference). Depending on their position on
the F CLASS case (front or rear panel), the test
and reference outputs may be reversed. The
pressurisation output is used for the addition of
ATEQ accessories (Y valve).

2.2.2. 4) Pneumatic supply
Air supply is via the filter located on the rear panel of the instrument.
It is essential that the air supplied is clean and dry. Even though there
is a filter, supplied with the instrument, the presence of dust, oil or
impurities may cause malfunction.
When the instrument is working in vacuum conditions, impurities must
be prevented from being drawn into its interior. For this purpose we
strongly recommend that a suitable airtight filter is installed between
the test part and the instrument. This filter can be supplied by ATEQ.
The presence of impurities, oil or humidity in the air may cause deterioration
which will not be covered by the guarantee.
In accordance with ISO standard 8573-1 concerning classes of compressed air for
measurement instruments in an industrial environment:
ATEQ recommends:
• Grain size and concentration CLASS 1 (0.1 µm and 0.1 mg/m
3
)
• Dew point under pressure CLASS 2 (- 40° dew)
• Maximum concentration of oil CLASS 1 (0.01 mg/m
3
)
ATEQ recommends the installation:
• of an air dryer to provide dry air at less than - 40° dew point,
• of a 25 micron and 1/100 micron double filter.
Optimisation of operation:
The supply pressure must always be between 4 and 8 bar to ensure that the pneumatic
distributors operate with optimum efficiency.
When a mechanical regulator is used, the supply pressure must be a minimum of
100 kPa (1 bar) greater than test pressure with a minimum of 400 kPa (4 bar).
