UNAUTHORIZED USES:
• Environments with explosive atmosphere
• Environments with inflammable or corrosive gas
The ba eries have to be checked at least once per year.
Ba ery acid may destroy internal components!
1.1 Delivery
The instrument is tested in all its parts, it is calibrated and configured with standard data.
1.2 Transport
The device is made of electronic components. In case of transport pack it carefully. Pay a enon
to both strong shocks and humidity.
1.3 Disposal
The instrument is a professional apparatus, compliant to the direcves 2011/65/EU (RoHS) and
2002/96/CE (WEEE). Before to remove the instrument, you disconnect first all electrical cables
and all connected cables. Take care that any calibraon circuit has to be unpressurized (open to
atmosphere) before you dismount the device. The instrument must be wrap in a plasc package or
in a cardboard box and deliver to companies which are specialized in scrapping of electric and
electronic wastes in accordance to the laws of the country where the device is commercialized.
If the instrument is not used for a longer period of me, dismount the ba eries, see chapter 7.1

designed for measure and display of pressure and should not be used for different purposes. The
instruments consists of a long term parcularly steady analogue secon and of a A/D 16 bit
converter which guarantees a max. of 65.000 internal divisions.
The various versions are proposed for different applicaons such as instruments for metrological
laboratories to be used as first or second line sample, for industrial applicaons for data
monitoring and transmission, for processes control or for tesng material equipment, presses, test
benches etc.
The AUTO POWER OFF funcon, if there is not any pressure change, switches the instrument off
aer a certain me, programmable, up to 30 minutes. The operator can select the measurement
unit, the resoluon and a digital filter according to the applicaon.
On the display there is a bar analogue indicaon of the pressure which is always acve, also inside
the programming menu.
The sensor is executed in stainless steel with a monolithic structure free of any O-ring or gaskets.
These features guarantee a long-term high stability and strength, even with highly dynamic
pressures or in vacuum measurements. Thanks to the most advanced strain gauges technologies
the instruments ensure a long term marginal dri.
Main features:
1 year autonomy, programmable resoluon, programmable digital filter, programmable baud rate,
zero funcon, peak funcon (posive and negave) and oponal a RS232 serial output.
