BEINAT MT User manual

Belonging
MT
MT is an innovative product combining the elegance and prestige of the BEINATs.r.l brand with the
versatility of a multi-functional instrument.
It offers two products in a single appliance:
a pressure gauge, thermometer.
Its main use is to assist technicians carry out their work, both during the installation of new systems
and the inspection of existing ones.
Thermometer
Temperature is measured using a built-in, hidden probe and detected from -50 °C to +100 °C, with
0.5 °C resolution.
Pressure Gauge
It ‘a differential portable compact pressure gauge easy to use. The accuracy and autonomy make this
an indispensable tool for testing and control of heating systems.
It is calibrated with sophisticated testing machines, so its measurement is very precise and is also
calibrated example for:
Pressure of gas mains; Gas pressure to burner nozzles; Flue efficiency.

To achieve long, satisfactory use of the MT digital appliance, use and store it in compliance with the following
precautions.
ENSURE the detector is intact after removing it from the packaging.
Any use other than the designed use of the detector is considered improper and BEINAT S.r.l. declines all
liability for any damage caused to people, animals or property.
Do not allow it to get wet.
The MT is not waterproof and can be seriously damaged if immersed in water or exposed to high levels of
humidity.
Do not drop it.
Heavy knocks on hard surfaces and strong vibrations can damage the machine.
Avoid strong magnetic fields.
This detector should not be used or stored near radiation or strong magnetic fields. Static electricity or magnetic
fields generated by devices such as radio transmitters can cause interference during measurements.
Avoid abrupt temperature fluctuations.
Sudden temperature variations can cause condensation and the batteries could supply lower voltage.
Over a certain temperature (circa + 45°C) the monitor becomes black. To restore visibility place it in a fridge
for a few minutes to allow it to cool.
Cleaning
Never clean the appliance using chemical products. If necessary, wipe with a damp cloth.
Read the following safety precautions carefully to avoid damaging the product or personal or third party
injuries, before using the MT appliance
Keep them safe so they are available for consultation by anyone before using the appliance.
Immediately turn off the appliance in the event of malfunctioning.
In the event you detect smoke or a pungent or unusual odour coming from the appliance or power supply
(optional accessory):
Immediately turn off the detector; disconnect the power supply from the mains, if connected to charge the
battery, and send to the nearest Service Centre.
Do not try to dismantle the appliance.
Contact with internal components of the detector can cause injury. In the event of faults, the product should
only be repaired by qualified personnel.
If the device is broken due to a fall or crash, consult the Service Centre for the necessary repairs.
Observe due precautions while handling the Lithium Polymer battery.
The battery must never be exposed to high temperatures, that is, over + 45°C. To ensure an optimum
service life, use it at room temperature.
If used at low temperatures, the service life could be diminished.
Never dismantle the battery and never throw it on a fire as it may explode.
Never dispose of the battery as normal waste. Comply with local regulations on its disposal.
Use the correct cables supplied.
To ensure the product complies with standards, for terminal input and output connection only use the cables
supplied for this purpose or those sold separately by BEINAT S.r.l.
Avoid contact with liquid crystals.
In the event the display breaks, pay attention not to injure yourself with the glass fragments and avoid the
liquid crystals coming in contact with your skin, eyes or mouth.
For your safety

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.
Checking pressure
The pressure gauge has two measuring inputs, one for the pressure (positive) and one for the depression
(negative).
To measure the positive pressure, apply the supplied tube on the input on the left making sure to let
opened the entrance to the depression.
To measure the negative pressure (depression), apply the tube on the input on the right making sure to
let opened the input pressure.
To measure the difference of two pressures, apply the higher pressure on the positive input and the other
on the negative input.
After the reading, appear on the display the pressure difference that the instrument will measure between an
input and the other.
1) Turn on the instrument as above
2) Insert the tube in the “Press” input
3) Use the tube to connect the instrument to the pressure or depression source, for measurement; the
instrument measures both positive and negative pressure.
PRESSURE GAUGE Function.
Press the
button and then the “Press” function button.
PRESSURE GAUGE Function.
Press the “Press” button to access the Pressure Gauge function with its mmH2Oscale;;
When the instrument is switched on it positions itself on the 999 mmH2O scale
If the pressure measured is higher, the instrument automatically positions itself on the higher scale of
999 mmH2O.
If you want to use the mbar scale, press the “Press” button again.
The instrument positions itself on the 30.9 mbar scale.
If the pressure measured is higher, the instrument automatically positions itself on the higher scale of
150 mbar
SWITCH OFF. Press the OFF button for 5 seconds.

Three macroscopic variables are necessary to define the state of static air, each subject to direct measurement.
These variables are pressure, temperature and volume; the state of gas in the air with 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.
Example:
Scale 99.9 mmH2O at each °C variable, the pressure varies by +/- 0.7 mm H2O
Scale 999 mmH2O at each °C variable, the pressure varies by +/- 3.4 mm H2O
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.
The MT digital instrument leaves the factory with a testing and calibration certificate.
Such calibration corresponds to that declared by the test instrument, according to international standards.
N.B. The test instrument is kept in the manufacturing plant.
Measurement uncertainty is assessed as “category B”
Ordinary and extraordinary maintenance of the digital pressure gauge and CALIBRATION, whose natural
validity is ONE YEAR, must be carried out by authorised personnel with equipment in compliance with
standards.

Rechargeable Battery
This device is equipped with a 3.7V rechargeable LITHIUM POLYMER battery.
To recharge the battery it should be connected to the PC using a USB cable or you can purchase a 230V
recharging cable separately.
When first turned on
On purchase the batteries are not fully charged.
Before using the instrument we recommend you charge the batteries for a maximum of 10 hours.
Charging.
1 Connect the battery charger connector to the micro USB socket on the lower part of the instrument, and
connect this to the USB port of any PC.
2 Connect the battery charger connector with the power supply unit to the micro USB socket on the lower part
of the instrument, and then connect the battery charger to a power socket.
3 Do not recharge the battery in an ATEX zone.
Use
Batteries should never be exposed to high temperatures, or rather exceed working temperatures of -20°C to
+45°C.
To ensure an optimal service life, use at room temperature.
If used at both low and high temperatures its service life may be diminished.
Never dismantle the battery and never throw it on a fire as it may explode.
Never dispose of the battery as normal waste. Comply with local regulations on its disposal.
