GOOD PRACTICES AND SAFETY INSTRUCTIONS
Safety recommendations
If the device is supplied with 100/240VAC, it is mandatory to connect it to the ground with
a good link to the ground, to protect against electric hazard or electrocution.
It is dangerous to change the status of the outputs.
They can control power actuators or other equipment (mechanical, pneumatic, hydraulic,
electrical or other) which can cause serious personal injury and damage to surrounding material.
For safety and quality measurement reasons, it is important, before powering on the device,
to ensure that it is air supplied with a minimum operating pressure (0.6 MPa ± 15%).
Recommendations for the test environment
Keep the test area as clean as possible.
Recommendations for operators
ATEQ recommends that the operators who use the devices have training and a level of
qualification that correspond to the job to perform.
General recommendations
— Read the user manual before using the device.
— All electrical connections to the device must be equipped with safety systems (fuses,
circuit breakers, etc.) adapted to the needs and in accordance with the applicable
standards and rules.
— To avoid electromagnetic interference, electrical connections to the device must be
shorter than 2 meters.
— Power supply plug must be grounded.
— Disconnect the device from the mains before performing any maintenance work.
— Shut off the compressed air supply when working on the pneumatic assembly.
— Do not open a connected device.
— Avoid splashing water on the device.
ATEQ is at your disposal for any information concerning the use of the device under
maximum safety conditions.
We draw your attention to the fact that ATEQ cannot be held responsible for any
accident related to a misuse of the measuring instrument, the workstation or non-
compliance of the installation with safety rules.
In addition, ATEQ declines any responsibility for the calibration or the fitting of their
instruments that is not done by ATEQ.
ATEQ also declines any responsibility for any modification (program, mechanical or
electrical) of the device done without their written consent.

AIR QUALITY REQUIREMENTS
The air supplied into the device must be clean and dry. Even though the device is provided
with a filter, the presence of dust, oil or impurities may cause malfunction.
Air quality requirements according to ISO standard 8573
The air must be clean and dry.
The presence of impurities, oil or humidity in the air may cause deterioration which will not
be covered by the warranty.
When the instrument is working in vacuum conditions, impurities must be prevented from
being drawn into its internal components.
For this purpose we strongly recommend that a suitable airtight filter is installed between
the part under test and the instrument.
ATEQ recommends the following characteristics for the air supplied into the device.
Air characteristics ISO standard 8573 class
Grain size and concentration 0.1 μm and 0.1 mg/m3 Class 1
Dew point under pressure - 40° dew Class 2
Maximum concentration of oil 0.01 mg/m3 Class 1
Recommended additional equipment
ATEQ recommends the installation of this additional equipment:
— Air dryer to provide dry air at less than - 40° dew point
— 25 micron and 1/100 micron double filter.

Preamble
ATEQ D620, A UNIVERSAL FLOW METER
ATEQ D620 is a universal flow meter that measures flow rates through parts to test.
ATEQ D620 can memorise 128 different test programs.

FLOW RATE TEST
The ATEQ D6 series can do direct or indirect measurements. In both cases, the flow meter
can also work in depressurization (option).
Measurement principle
When the fluid (gas) enters the device1, it moves through a calibrated flow tube2which
causes a drop in pressure. The pressure drop is measured by a differential pressure sensor3.
The pressure of the part under test 5 is measured by the sensor4.

2Calibrated flow tube
3Differential pressure sensor
4Pressure sensor
5Part under test
Direct measurement
Once the part is filled, the device measures the flow rate through the part.
The test pressure is applied to the device1 and then to the input of the part under test2.

Indirect measurement
The indirect measurement (also called recovery mode or under bell) allows a considerable
gain in time as the flow which enters into the device is already stabilized.
The test pressure is first applied to the input of the part under test1and then to the
device2. The output of the device2is vented to the atmosphere.
This method allows to test the parts at a higher pressure test (up to 2 MPa).
1Part under test
2Device
Depending on the part type, it may be possible to use a bell (ex: shower head where it is
impossible to recover the flow other than through the use of a bell). This method can only be
used if the recovery of the flow is easy.

PRINCIPLE OF A CYCLE
The measurement cycle is made of 4 main phases: fill, stabilization, test, dumping.
An additional Pressure auto zero phase0can be placed at the start or at the end of a cycle,
depending on the requirement of the operator.
