Chap.2 - Security
a) Device
Device Identification
indicates the model of comparator
ex : CAA-20B
indicates the serial number of comparator
indicates the date of commissioning of the unit
Intended use of the device
Before switching on the device, ensure that the technical characteristics (measuring range,
precision, fluid etc...) correspond to your needs
> For example : the maximum pressure
defined for this compressor must not be
exceeded
The pressure comparator is designed and manufactured for use as described in this document
In this case of misuse or mishandling, outside the technical specifications contained in this
manual. The instrument must be immediately isolated, identified as inoperative and must be
checked by our service department.
Precautions storage and transport
It's necessary to take care of the unit during storage or transportation. It must be protected from
moisture, shock, extreme temperatures and shouldn't be removed or changed.
If the comparator is moved to a new environment (warmer, colder, etc..). Observe the phase of
"quarantine" and wait until the device temperature stabilizes at room temperature before
handling.

b) L'opérateur
User qualifications
> Improper use of the device can cause
significant bodily injury and properly
Qualified operator, due to : it's product training, knowledge in the field of metrology and
experiences in field of pressure and knowledge on standards and guidelines, is able to perform
the operations describes in this manual. He will be able to detect potential dangers.
AREMECA offers on demand, an installations / commissioning of the instrument performance.
Personal protective equipment (PPE)
The personal protective equipment must be defined in the security register of the user company

> wear gloves : protect the skin against
irritation, allergies.
AREMECA provides for oil dead weight, a bottle of colorless mineral oil. Safety data sheet of
used oils are available on request.
Chap.3 - Put into service

RE. ENR.212 - Rév A - Le 21/10/14 page : 8
a) Unpacking the unit
Upon receipt of the equipment, check the status and content of your package. All of the following
elements must be present in the package :
- 1 generator
- 1 capstan consists of 4 delivered arms removed
- 2 connectors G1/2 (supplied as standard unless otherwise specified)
- 1 manual
Check that there isn't damage or breakages during transport. If there are missing items, please
immediately notify AREMECA or your local distributor for what is missing.
b) Installation
Preferably, install your unit in a stable and controlled environment
You will get better performance if :
> the temperature and humidity of the room
are stable,
> the workstation is clean and dry,
protected from drafts, noise, vibration,
and without passing

Installation / Assembly
- Install the pressure generator on a stable place
- Insert the capstan 1 on the axis of rotation 2, screw the clamping knob 3 to the axis of rotation.
- Remove the yellow caps protections pressure connections.
- Make sure the O-rings are positioned in their throats.
- Place the two connectors rotating G1/2 .
- Make sure that o-ring are well positioned.
- Close the valve A

- if necessary, connect the pressure source 6 on the output ¼ cylindrical gas located at the rear of the
generator 20 bar maxi
Note : Use a clean gas, dry, no agressive and no toxic as nitrogen U. Provide a single regulator at
the output of the pressure source.
> Dirty or polluted gauges must be cleaned
before mounting the pressure generator to
prevent contamination on the hydraulic
circuit. Don't clean the tank with alcohol
Option : cleaning bench (Ref.OP0062)
Be careful with the valves
- Maximum torque applicable abutment valve open = 0,3 Nm
- Maximum torque applicable abutment valve closed = 4 Nm.
When the abutment valve open is reached, turn the wheel valve 1/4 turn clockwise.
c) Put into service
> the generators are equipped with
precision valves instrumentation, it is
imperative to observe the following
guidelines to keep your machine in good
working condition.
1. Install on the left connector G1/2 your reference instrument
2. Install on the right connector G1/2 your instrument to be tested
3. Make sure the the valves A and B are closed
4. Check the capstan 1 is in the stop end position. Turn it in the opposite direction of clockwise.
5. Supply the generator with air and check that the value reading on the manometer is located in a
range of the pressure desired for calibration.
6. Open the valve A, the generator load pressure gas
7. Close the valve A
The generator is ready to use
d) Test run after installing
1. Perform a calibration test instrument with a "test" known correct (see chapter procedure) to verify
and validate the operational statues of the pressure generator

RE. ENR.212 - Rév A - Le 21/10/14 page : 10
2. The device is now ready to use.
Chap. - Procedure

RE. ENR.212 - Rév A - Le 21/10/14 page : 11
Procedure for pressure generator model CAA-20B
> Pneumatic diagram
> Pressure mounted
> Observe the maximum operating pressures
of the pressure generator
Maximum operating pressure : CAA-20B  20 bar
a) Install the reference instrument and the instrument to be tested on the connectors.
b) Make sure tha the valve A is close, and open the valve B.
c) Turn the capstan 1 in the opposite direction of clockwise until the stop end "a".
d) Close the valve B.
e) The device is now ready for use.
You can now generate the pressure to the desired value.
f) using the capstan and turn in the direction of clockwise, the cursor moves to the point "z". Maximum
working pressure is 20 bar. If the generator is conencted to a pressure source, you can also use the
valve A.
> Reduce pressure
Turn the capstan in the opposite direction of clockwise and replace the cursor in position "a" and open
the valve B
Note : Before removing the calibrated device, set the generator at atmospheric pressure by opening the
valve B to purge the system. "
Work up to -900 mbar vacuum
a) Install the reference instrument and the instrument to be tested on the connectors.
b) Open the valves A and B.

valve B to purge the system. and replace the cursor in position "a"
Chap.5 - Cleaning/Maintenance
a) Cleaning

RE. ENR.212 - Rév A - Le 21/10/14 page : 13
The generator cleaning and checking fluid levels are the only periodic maintenance required. No
additional maintenance should be necessary if all instructions are followed.
We recommend a complete overhaul of the unite every 2 years. This operation can only be
performed by the manufacturer. If necessary, send us your device for maintenance. A complete
assessment of your device will be made and an estimate of rehabilitation will be sent.
Instructions reminders :
- Use only a clean and dry air like nitrogen. This unit is not compatible with oxygen
- Don't remove the device.
b) Maintenance
> Piezometric set
It's designed for extremely narrow limits of accuracy. It's forbidden to disassemble it.
> Valves
Generator and dead weight are equipped with instrumentation valves, it's imperative to observe
the following guidelines :
- Maximum torque applicable abutment valve open = 0,3 Nm
- Maximum torque applicable abutment valve closed = 4 Nm.
When the abutment valve open is reached, turn the wheel valve 1/4 turn clockwise.
c) Inspection
It's recommend to a service of your device every 2 years. The average response time is 2 weeks.
Cleaning generator, replacement o-rings, testing pressure rise and stability are made.
d) Connection
The device is equipped with a specific connector for less than
1250 bar pressure. It is necessary to orient the ring according to
the type of connector correctly.
