OVERVIEW
This device is a digital handheld gas leakage detector,
equipped with an external whip (for reaching the point in
which the leakage is likely to happen) at whose end is
mounted a gas semiconductor sensor for detection of low
concentrations of hydrocarbons in gas appliances and pipes.
WARNING!
This device is not a measurement instrument.
This device can detect either Methane (CH4) or LPG (a
mixture of isoButane and isoPropane, but generally to several
types of Hydrocarbons.
The gas concentration is shown through the 4-digits LCD, as well
as through a bar-graph ranging from 0 to 100% of the full scale.
The instrument is featured with the auto zero and self-
shutdown functions.
DETECTOR POWER SUPPLY
The detector is featured with an internal Li-Po rechargeable
battery pack.
The recharge is made by connecting an external power
supply (5V, min.0,5A/h – not provided) to the USB Type B
connector. In case of necessity it is possible to recharge the
detector battery by connecting it to the PC or using a power
bank, as long as it has a 5 volt output and a minimum current
of 0,5A/h.
WARNING!
THE INSTRUMENT IS SENT WITH A MEDIUM LEVEL OF
BATTERY CHARGE, IT IS ADVISED TO PERFORM A
COMPLETE BATTERY CHARGE CYCLE, WHICH LASTS 4
HOURS.
IT IS ADVISED TO PERFORM THE RECHARGE AT A
ENVIRONMENT TEMPERATURE INCLUDED IN THE
RANGE 10 °C .. 30 °C.
The device is featured with two led placed on the front cover,
and they provide the following information when charging the
battery pack:

COMMANDS DESCRIPTION
'
' On/Off key
In order to turn the instrument On or Off press the '
When the instrument is turned on the instrument plays a short
beeping sound and starts the sensor pre-heating phase,
which lasts 45 seconds.
During this phase the instrument displays the word 'HEAT'
and the remaining time before the end of it.
When the pre-heating is terminated the auto-zero phase is
initiated, lasting 6 seconds and identified with another short
beeping sound. Once also this is terminated, another
prolonged beeping sound indicates the full functionality of the
instrument.
During normal operation, while no gas is detected, the
instrument will issue a short beep every 2 seconds.
In case a leakage is detected, the rate of the sound will be
higher accordingly to the measured concentration.
The instrument is factory set with the auto-shut-off feature
turned on and the relevant time set to 10 minutes.
This means that the instrument will automatically turn off after
ten minutes from turn-on.
A temporary turn-off for this feature (until the first manual turn-
off) can be accomplished by pressing the '
4 seconds during the turn-on phase. In order to turn the
instrument off please press the
confirmed with three short beeps issued in sequence.
' >0< ' AUTOZERO key.
When this key is pressed (an the instrument is on) the auto-
zero procedure is initiated.
As previously explained, the auto-zero time is 6 seconds long,
stressed with a beeping sound and with 4 '0.000' digits
flashing on the LCD.
During this phase the instrument samples the actual gas
concentration and assumes that as a zero baseline for any
following measurement.
When this phase is terminated, the instrument will sound a
prolonged beeping sound.
AUTOMATIC Zero drift adjustment
In absence of gas the instrument continuously checks its zero
level and performs an automatic drift adjustment, provided the
variation is maintained within some limits.
This compensation is transparent for the user and it is
performed every 2 seconds in order to compensate any
possible sensor drift mostly due to temperature variations.
When the sensor detects the presence of gas it abandons this
compensation procedure and switches to the gas detection
operation.
' H ' Hold key
When the 'H' key is depressed, the 'HOLD' mode is started,
during which the actual read value is 'frozen' on the lower 4
digits display. When in this mode the instrument truns the
label 'HOLD' on and issues a short beep.
During this mode the upper 4-digits display will keep on
showing the current measured concentration value (thus
following the concentration variations), meanwhile the lower 4
-digits display shows the 'frozen' value.
If the 'H' key is again depressed the instrument will exit from
the 'HOLD' mode, sounding a short beep as a confirmation.
'UNIT' Measurement Unit Key.
When this key is depressed the measurement unit in which
the display reading is expressed is selected.
Every time the 'UNIT' key is further depressed, the instrument
will cycle among the available measurement units, according
to the following sequence (Starting with the unit currently
selected):
=> ppm => %vol => % L.E.L. => ppm =>
every time the unit is changed, the choice is automatically stored
