The MME500 pressure gauge is a high-tech product that embodies the innovation and
elegance of BEINAT S.r.l.
Its best privilege is to assist the installer in his work both during the installation of new
plants and in the testing of existing plants.
Pressure gauge
It is a small portable differential pressure gauge, with easy use. Precision and autonomy
make this tool indispensable for testing and controlling heating systems.
It is calibrated with sophisticated testing machines, so its measurement is very precise. It is
calibrated for example for the measurement of:
Network gas pressure
Pressure in the combustion chamber
Fireplaces efficiency
For your safety
To prevent damage to the product or injury to you and third parties, read the following safety warnings carefully before using
the equipment.
Store so that anyone using the appliance can consult it in advance.
If you notice smoke escaping or an acrid or unusual odor coming from the instrument, and in case of malfunction, immediately
switch off the device, and send it to the nearest service center.
Do not attempt to disassemble the appliance.
Contact with internal parts of the detector can cause injury.
In case of fault, the product must be repaired only by qualified personnel.
Avoid contactwith liquid crystals.
In case of breakage of the display, be careful not to injure yourself with the glass fragments and avoid that the liquid crystals
come into contact with the skin, eyes or mouth.
To use your digital equipment for a long time and with satisfaction, use it and store it keeping in mind the following precautions.
MAKE SURE the integrity of the product after removing it from the packaging.
Any use other than that for which the detector was designed is to be considered improper, so that BEINAT S.r.l. declines all
responsibility for any damage caused to people, animals or things.
Do not wet it.
The detector is not waterproof, if immersed in water or exposed to high humidity it can be seriously damaged.
Don't let it fall.
Strong blows against hard surfaces and large vibrations can damage the appliance. Should the appliance break down after being
dropped or crushed, consult the Service Center for necessary repairs.
Avoid strongmagnetic fields.
This detector should not be used or stored in the presence of radiation or strong magnetic fields, static electricity or magnetic
fields produced by equipment such as radio transmitters may interfere during detection.
Avoidsuddenchangesintemperature.
Sudden changes in temperature can cause condensation and the batteries could supply less current.
Over (+ 45 ° C c / a) the monitor may turn black, to make it visible again it must be cooled by placing it in the refrigerator for
a few minutes.
Cleaning
Never clean the appliance with chemical products. If necessary, wash with a damp cloth.

Readings and Measurements
These operations must be carried out in compliance with the methods described in this manual.
Remember measurements taken with batteries in need of recharge can give false measurements.

Technical specifications
500

Three macroscopic variables are necessary to define the state of static air, each subject to direct measurement.
These variables are pressure, temperature and volume.
V, pressure Pand temperature Tis defined by Boyles Law:
P*V =n*R*T. where n is the number of moles composing the gas and R is a universal constant.
The possible states of a gas with constant pressure and volume are expressed by the Gay-Lussac Law: with
constant pressure the volume of a gas increases as the temperature increases, or vice versa
Therefore, if the instrument is connected at variable temperatures, the pressure registered at the start will
definitely differ from final pressure.
This is normal and is not due to malfunctioning..
For each degree C. of temperature the pressure varies by c / a 10 mmH2O

To power the instrument on, keep the button pressed for 5 seconds.
The instrument automatically positions itself on the minimum scale "from 0 to 99 mbar"
Display reading:
max. 99.9 mbar.
N.B.The scale exchange

Pressure Control
The pressure gauge has two measurement inputs, one of pressure (positive) and one of depression
(negative).
1) To measure the positive pressure, apply the supplied tube to the "RIGHT" input, making sure to leave
the "LEFT" input free. Minimum Input.
2) To measure the negative pressure (Depression), apply the supplied tube to the "LEFT" input, making
sure to leave the "RIGHT" input Maximum Input open.
3) To measure the difference of two pressures, apply the higher pressure to the positive inlet and the
other to the negative inlet.
Finita la lettura, sul display apparirà la differenza di pressione che lo strumento misurerà tra un ingresso e l’altro.
Turn on the instrument as described above
2) Insert the tube into the desired inlet
3) Connect the instrument, through the small tube, to the source of pressure or depression, which must be
measured.
