GAS LEAK DETECTOR
TEN01068
Useage
This Gas-leak detector is a very sensitive, self-sufficient warning system. The device
consists of a gas sensor, an acoustic signal generator, a visual status-display and a power
supply.
The device responds to the following types of gas: natural gas and propane. The device
serves to recognize gas leaking from small liquefied-gas containers, such as camping-gas
cartridges, gas lighters, gas soldering torches, etc.
The device is not suitable for continuous operation, but only for short-time operation (note
lifetime of battery).
The device is to be considered as an aid only and must only be used for small gas
containers, such as lighters, camping-gas containers etc.. If there is reason to
believe that gas is leaking, especially in case of complex gas systems, such as
heaters or ovens, you should not carry out the measurement yourself, but contact
an expert. The device is not suitable for those types of measurements. Do not put
yourself at risk. In case of leaking gas, leave everything else, especially the repair,
to an expert who is familiar with the relevant dangers and regulations.
The device is not designed for industrial use.
Also note all other safety instructions contained in this operating manual.

Make sure that the products is commissioned properly.Adhere to the instructions in
this operating manual.
Never pour liquids over the gas-leak detector. This may damage the device. If this
occurs accidentally remove the batteries immediately.
Do not expose the device to high temperatures, dampness or strong vibrations, nor
to high humidity.
Avoid serve mechanical stress. The gas-leak detector is equipped with high-quality
electronics and is, therefore, very sensitive to impact, mechanical shock etc., which
may destroy the gas sensor. Furthermore, the gas sensor (1) may be damaged or
destroyed by blowing strongly and directly onto it, or by moisture.
Handle the gas-leak detector with care.
If you are not sure about the operation, safety or connection of the devices, please
contact a qualified engineer.
Keep the device out of reach of children.
Control elements
(1) Gas sensor
The sensor is the heart of the gas-leak detector. It recognizes gas and transforms
this information into electrical impulses gas and transforms this information into
electrical impulses which ca be read out by the analysis electronics
(2) Gas display LED
This LED shines when the device triggers an alarm due to the detection of gas.
(3) POWER display LED
This LED shines when the device is switched on and the batteries still have
sufficient capacity.
The LED does not shines when the batteries are too low or flat.
(4) STATIC display LED
This LED shines as soon as the device recognizes a static discharge.
(5) Circuit breaker/circuit closer(ON/OFF)
This switches the device on and off. In the “ON” position the device is switched on
and in the position the device is switched on and in the “OFF” position the device is
switched off.

(6) Carrier sling
The carrier sling is intended to prevent accidental slipping of the gas-leak detector.
Fasten the carrier loop to the respective fastening eyelets at the end of the detector.
(7) Cover
The cover portents the sensitive gas sensor from damage. Remove the cover
before operation and replace it when you have finished operating the detector.
(8) Battery chamber
The battery chamber serves to hold the two micro batteries which are necessary for
operation.
(9) Battery chamber cover
(10) Static aerial
Inserting the batteries and battery exchange
The device may be operated only with batteries.
Storage batteries are not suitable for operation.
Slide the battery chamber cover (9) off the device.
Insert two micro batteries into the battery chamber (8). The positive pole of the
batteries must point towards the gas sensor(1). Is possible, use alkaline batteries
since they ensure a longer operating time.
Close the battery chamber cover again.
The battery requires changing if the green display LED (3) does not iluminate
after the device has been switched on, or if the device no longer responds
properly.
Note: If the product is switched on in a room without any gas and starts to
make a continuous beeping sound, an inspection of the batteries is necessary
to check whether the batteries have run out or are running low.
To avoid damage caused by leaking batteries, remove the battery if the device is
not to be used for a long period of time.
Remove depleted batteries immediately.

Commissioning and operation
To ensure proper commissioning it is absolutely necessary that you read this
operating manual, including the safety instructions, completely and carefully!
Remove the cover (7)
Switch on the gas-leak detector by sliding the ON/OFF button (5) to the position “ON”.
The device produces a short beep. The red display LED (2) shines simultaneously
then the green LED (3) will shine. If the green LED does not shine, you will have to
exchange the batteries
If the device is switched on again shortly after having been switched off, the
switch-on procedure may deviate from the procedure described here; the device
may, for example, produce no beep tone or the red LED may not shine etc. This is
why, after switching it off, you should wait 60 seconds before switching the device
back on.
When the beep tone has stopped and the green display LED (3) shines, the device is
ready for operation. In order to detect any possible gas leak, hold the device with the
gas sensor (1) close to the object which is to be tested.
If the gas-leak detector detects leaking gas, this will be indicated by the shining of the
red display LED (2). A beep tone will also be produced. The device will terminate this
alarm status as soon as the concentration of gas falls below the detectable limit
value.
While using the gas-leak detector make sure that you pay attention to the
different behavior of different gases; liquefied gas, for example, is heavier than
air and settles on the ground. This is why the highest concentration of gas is
close to the ground. For more information ask at the relevant gas power plant
or ask an expert. If the flow rate of the gas is too high this may damage the gas
sensor. For this reason you should never place the gas sensor directly in a
strong air/gas current.
Static discharge
The STATIC display LED (4) will illuminate for a short period of time as soon as the
device detects a static discharge. A static charge from the human body is often
created in a dry environment and when synthetic materials are rubbed. This charge
can discharge with a spark while touching an earthed object, for example a heater.
At the bottom of the device, a small wire can be seen which projects out of device.
This wire is the “aerial” which is necessary for the detection of the discharge.
Before a gas-detection operation, touch the small wire at the bottom of the device and
touch an earthed object, for example a radiator, with your other hand. If you are
statically charged, the STATIC display LED (4) will shine for a short period of time.
This measurement must not be carried out in the same room in which the gas
detection is carried out, since leaking gas may be ignited by the sparks created.

The STATIC test should always be carried out before a gas-detection operation. If there
are strong charges, a gas-detection operation should not be carried out, since the static
charge is renewed when a person moves around and new sparks may be created during
the gas-detection operation.
Alarm
If the detector produces an alarm (beep tone and red LED illuminates), gas is leaking from
the object. Depending on the amount of leaking gas, you should immediately open all
windows and doors, and avoid both open fire and the creation of sparks. Do not operate
electrical switches. Leave the room. If possible, turn off the gas supply.
You should immediately inform a qualified gas engineer about leaking gas
systems. Do not try to deal with the fault yourself!
Testing the gas-leak detector on a known source
Hold a gas lighter close to the gas sensor (1). Let gas leak out of the lighter without the
flame of the lighter burning. The gas-leak detector should now produce a beep tone and
the red display LED (2) should illuminate. If this is not the case, either the batteries are
depleted or the gas-leak detector is defective.
False alarm
Due to the high sensitivity of the detector, a false alarm due to other gaseous materials
such as aerosols (hair sprays, propellant gas, cigarette smoke etc.) cannot be excluded.
Maintenance
Check the gas-leak detector regularly for technical reliability. It can be assumed that safe
operation has become impossible, if:
the device shows visible damage
the device was stored under unfavorable conditions for a long period of time
it was exposed to extraordinary stress caused by transport
the test function described above no longer works correctly.
Use a soft cloth or brush to clean the outside of the device. Never use abrasive pads or
chemicals, since they may damage the housing or impair the function of the device.
Avoid touching the gas sensor (1) or cleaning it in any way. Apart from the battery
chamber, do not try to open the housing.
