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 shines), 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 an expert about leaking gas systems. Do not try to deal with the fault yourself!
8. Inspecting the gas-leak detector
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 shine.
If this is not the case, either the batteries are empty or the gas-leak detector is defective.
9. 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.
10. Maintenance and disposal
Maintenance
Check the gas-leak detector regularly for technical reliability. It can be assumed that safe operation has become
impossible, if:
z
the device shows visible damage
z
the device was stored under unfavourable conditions for a long period of time
z
it was exposed to extraordinary stress caused by transport
z
the test function described above no longer runs correctly.
Use a sort, dry cloth or brush to clean the outside of the device. Never use aggressive cleaning agents 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.
Disposal
Dispose of the unserviceable device according to legal and statutory regulations.
