Intended Use
Scope of Delivery
The ecom-LSG is developed for the detection of leaks in gas installations.
The unit shows existing gas concentration on the display and warns by
means of an optical and acoustic signal. The sensitivity of the sensor can
be adjusted so that even small leaks can be detected. The sensor head is
connected to a movable flexible tube, so that even parts of the installation
which are difficult to access can be reached.
• ecom-LSG
• 2x 1.5 V AAA Batteries

General safety instructions
NOTICE
Do not switch on ecom-LSG in air containing gas, as this will lead to
inaccurate measured values!
CAUTION
Damage to the Sensor
Vibrations can damage the sensor head.
Avoid shocks to the sensor head.
WARNING
Hazard of Injury
Improper work on gas pipes can result in injuries.
Work on gas pipes may only be carried out by qualified personnel.
When working on gas pipes, observe the applicable safety regulations.
CAUTION
Damage to the Sensor
Substances such as silicones, halogenated hydrocarbons, lead tetra-
ethyl, sulphur compounds and organic phosphorus compounds lead
to partially irreversible sensitivity losses.
Avoid contact with such substances.

NOTICE
NOTICE
Hold the On/Off key down until you hear a signal.
1 Bar = no concentration
14 Bars = max. concentration
1. Switch on the device.
2. Wait for the heating-up phase.
3. 3-fold beeps indicate operational readiness.
4. Display shows the gas concentration as a bar chart.

Leak detection
Zero Point
CAUTION
Damage to the Sensor
Substances such as silicones, halogenated hydrocarbons, lead tetra-
ethyl, sulphur compounds and organic phosphorus compounds lead
to partially irreversible sensitivity losses.
Avoid contact with such substances.
1. Slowly move the sensor head past the gas installation to be tested.
2. As soon as the ecom-LSG approaches a leak, the measured value
display reacts.
NOTICE
If the first switching threshold is exceeded, the red LED flashes and an
acoustic signal sounds. With increasing concentration, the LED flashes
at shorter intervals and the signal tone becomes more intense.
3. The highest gas concentration registered so far is represented by a
grey bar.
Deviations of the bargraph display from zero can be set to zero by pressing
the HOLD key. The change of the zero point is indicated by flashing of the
first bar. If the HOLD key is held down for more than 2 seconds, the original
zero point is reset.

Settings
Sensitivity
1. With the machine switched on, press the On/Off key.
2. Press the HOLD key.
• Small bars = low sensitivity
• Middle bars = medium sensitivity
• Large bars = high sensitivity
Battery Capacity/Setting Menu
1. With the machine switched on, press the On/Off key twice.
2. Battery capacity is displayed.
NOTICE
If 4 bars are shown on the display, the battery capacity is sufficient for
about 1 hour.
3. Use the HOLD key to make the following settings:
• Without lighting/without acoustic signal
• With lighting/without acoustic signal
• Without lighting/with acoustic signal
• With lighting/with acoustic signal
4. Press the ON/OFF key to save the selected setting and exit the
menu.
Switch-off
• Press and hold the ON/OFF key until no more bars are visible on the
display.

Functional Check
1. Open the test medium bottle.
2. Hold the sensor head over the opened test agent bottle.
NOTICE
The bar indicator should show a clear reaction, otherwise the
sensor is defective and must be replaced.
Power Supply
Battery Change
1. Open the battery compartment on the back.
2. Remove old batteries.
3. Insert new batteries.
4. Close the battery compartment.
The two 1.5 V AAA batteries must be replaced when a grey battery symbol
appears in the top left-hand corner of the display. The remaining capacity is
1 hour. If the voltage drops further, the battery symbol turns black and the
unit switches off automatically.

Disposal
Maintenance
• Dispose of used batteries at the designated collection
points.
• Dispose of packaging material in an environmentally friendly
manner.
• Old devices must be disposed of in an environmentally
friendly manner by an authorised centre.
NOTICE
On request we take back old appliances and dispose of
them in an environmentally friendly way.
To ensure the accuracy of your measuring device, we recommend an annu-
al inspection by an authorised ecom partner. In case of heavy use, shorter
inspection intervals should be chosen – please contact your ecom partner.
