Sensitivity setting
The leakage detector disposes of 2 sensitivity stages. If you have switched on the device, it
automatically goes to the highest setting (HIGH). In order to modify the sensitivity, press the key
LOW Sensitivity and the two green LEDs are flashing shortly. Then press the key HIGH
Sensitivity and the red LEDs are flashing shortly.
How to detect a leakage?
Note: Sudden, high swiveling with the flexible probe or blowing in the opening of the probe will
cause a false alarm.
Device ON/OFF:
Press the ON/OFF key. The device is switched on and the LEDs are flashing. After about
90 seconds of warming-up time of the probe of the device is ready for further settings and then
you hear a danger signal. Press the key ON/OFF again and keep the key pressed for about
5 seconds, then switch off the device.
Auto RESET – function key:
If you have switched on the device, you are automatically in the high sensitivity mode.
Press the key LOW in order to reduce the sensitivity. The 2 left green LEDs shortly flash and
then only the 1st LED is illuminated. Press the key HI in order to increase the sensitivity and the
red right LED flashes.
Testing the settings of the device and of the probe:
- Set the highest sensitivity level.
- Open the bottle containing the test agent and slowly approach the probe tip.
- If the LED display moves from low to high, you can remove the bottle and close it. Then the
LED display must fade out. This indicates that the device is correctly set.
- If the device does not work as described above, return the device to your supplier for
inspection.
- Note: The test bottle must have room temperature. If it is too cold, warm it up with your hands.
Indications for leakage detection:
Approach the measuring tip of the leakage detector as near as possible to the expected
leakage. However, make sure to keep a distance of about 5 mm. Then slowly run the probe tip
along the gas line and the connections. If the device detects a leakage, you will hear a danger
signal and the LEDs are flashing from left to right, from green to red. If the highest concentration
is displayed, you have detected the leakage.
In order to make sure that this is the leakage, remove the measuring tip from the detected
leakage and approach the measuring tip once again to this point. The danger signal and the
illumination of the LEDs must appear again. In case of a larger leakage, you should perform the
leakage detection at the LOW position and, if necessary, change over to the HIGH position later
on. After completing the leakage detection, place the device again into
the carrying box in order to protect it.
Replacing the probe:
The probe is a wearing part and thus it has a limited service life of
about 1 year. High gas concentrations are having a negative effect on
the service life of the probe.
Always make sure that the surface of the probe is clean and free from
any soiling. Always immediately remove oil films or water drops using a
clean cloth.
Warning note:
If you want to replace the probe, it might be possible that the old probe is still hot.
Therefore, switch off the device and allow a reasonable period of time to cool it down.
1.) Remove the protective cover from the probe tip.
2.) Pull out the old probe from the socket and carefully insert the new probe in the provided
socket.
3.) Pull the protective cover over the probe again.
Cleaning the device:
It is possible to clean the plastic housing of the leakage detector using a clean, damp cloth and
a standard household cleaning agent, which is neither aggressive nor corrosive.
Note:
Treat the probe neither with a household cleaner nor with alcohol, but only wipe it with a cloth.
