z
Slide the battery chamber cover (9) off the device.
z
Insert two micro batteries into the battery chamber (8). The positive pole of the batteries must point towards
the gas sensor (1). Are possible, use alkaline batteries since they ensure a longer operating time.
z
Close the battery chamber cover again.
A battery exchange is necessary if the green display LED (3) does not shine after the device has been
switched on, or if the device no longer responds properly.
To avoid damage caused by leaking batteries, remove the battery if the device is not to be used for a long
period of time. or the same reason we recommend the immediate removal of empty batteries.
Environmental note!
The end user is legally required to return (old battery regulation)all used batteries and storage batteries
(round cells, lead acid batteries etc.); a final disposal together with domestic waste is not permitted.
You can return your used batteries and storage batteries free of charge either to our branches or to the
main office in Hirschau or to local disposal units (reusable waste facilities) which are obliged to accept
returned batteries. Contribute to environmental protection!
6. Commissioning and operation
To ensure proper commissioning it is absolutely necessary that you read this operating manual, including
the safety instructions, completely and carefully!
z
Remove the cover (7)
z
Switch on the gas-leak detector by sliding the ON/OFF button (5) to the position “ON”.
z
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.
z
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.
z
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 behaviour 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.
7. Static discharge
z
The STATIC display LED (4) will shine 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.
z
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.
z
Before a gas-detection operation, touch the small wire at the bottom of the device and touch an earthed
object, for example a heater, 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.
