4. Initialisation
4.1. Power supply
The ecom-DP is powered by 3 batteries or 3 accumulators. The following types can be used to operate the
instrument:
- Battery 1,5 V AA (Mignon)
- Accu 1,2 V AA NiCd (nickel cadmium)
- Accu 1,2 V AA NiMh (metal hydride)
If you are using a accu charger, please adjust the function „Bat. Loading“ (see chapter 8.4.)
Open the battery compartment and insert the batteries.
Be careful to ensure proper polarity. If using the rechargeable battery type, it will be necessary to fully
charge the batteries prior to initial use (approx. 4 hours).
The voltage of the batteries is monitored by the DP and
will indicate a low battery condition by approx. 3.3 V by
beeping and flashing a signal on the LCD display. If the
voltage sinks (approx. 3 V) so the ecom-DP will automatically switch off.
4.2. Accu charging
The accu charging procedure is monitored by the ecomDP. Once connected to AC power, the instrument
switches on. During the charging procedure, a BATTERY indicator will be shown on the LCD display. Once
the battery is fully charged, the BATTERY indicator on
the display will blink. It is possible to operate the ecomDP on AC power during the charging procedure by
pressing the <ON> button.
4.3. Setting clock
The internal clock and the internal RAM memory of the
ecom-DP are buffered via a capacitor. If the instrument
is without current supply during more than approx. 10
minutes, the recorded information gets lost. Before using the ecom-DP for the first time, adjust the internal
clock and delete the internal RAM memory.

1. Application
The gas leak detection head ecom-LSG is engineered for the quick and reliable
detection of untight gas installations. Reverse to leak detection sprays which can
rise and re-seal e.g. hemp sealings, the leakage detection with the ecom-LSG is
made easy and without problems.
The unit shows existing gas concentration on the display and warns with optical
and acoustical signals. The sensor sensibility can be adjusted, so that even small
leakages can be traced. The robust sensor head is connected with a flexible
swan-neck, so that also hardly accessible system parts can be reached.
Please respect the legal safety instructions
by works at gas pipes!

3. Power supply
The ecom-LSG is delivered with two batteries 1,5 V AAA (Micro). Alternatively
the following accu types can be used:
1,2 V AAA NiCd (Nickel-Cadmium)
or 1,2 V AAA NiMh (Nickel-Metal-Hydride)
Low batteries/accus are indicated by a grey battery symbol at the left side of the
display (capacity for approx. 1 h). If the voltage further sinks, the battery symbol
will turn to black and the ecom-LSG will switch off automatically.
For recharging the accus you can use the charging station (option).
4. Battery Change
Open the battery compartment located on the back of the instrument and exchange the batteries (respect polarity). Always dispose of used batteries and accumulators in official recycling containers only (e.g. in battery shops).
5. Operation
Switch on the ecom-LSG in gas-free air. Hereto press the <I/O> key until a beep
is given. The instrument starts a warm-up phase during which the sensor is set to
operation temperature (running bar graph on display). After warm-up phase the
operability is signalized with 3 beeps and display shows the current gas concentration as bar graph:
-no gas cocentration = 1 line
-gas concentration > 0,5 % = 14 lines
If necessary (strong ambient noise) the headphones (in ear) can be connected to
ecom-LSG (headphone connection). Please use only the supplied headphones
from ecom.
Page 22 ecom-DP
Page 23
6. Leak Detection
Sweep the sensor head slowly along the gas installation to be checked. As soon
as the unit nears a leakage, the display indication reacts and, by exceeding the
first threshold (2 lines in display), the red LED blinks.
The blinking red LED together with an acoustical signal (disconnectible) shows
an increased concentration of gaseous hydrocarbons. Parallely to the increasing
concentration, the signal tone is getting more intensive and the red LED blinks in
shorter intervals, so that a leakage can be accurately localized.
The largest concentration registered so far is displayed with a grey bar (dragging
announcement). The sensitivity of the sensor (middle sensitivity after switching
on) can be adjusted in 3 steps (see Adjustments).
Substances such as silicone, hydrocarbons, leadtetraethyl,
sulfur connections and organic phosphorus connections
cause partially irreversible sensitivity losses
(sensor poisoning)!
7. Zero Point
Indication drifts from the zero point can be corrected while pressing the <HOLD>
key (dragging announcement gets erased). pressed longer than 2 seconds. The
change of the zero point is indicated by flashing of the first bar. If the <HOLD>
key is kept pressed longer than 2 seconds, the original zero point gets back (no
flashing of the first bar).
ecom-DP Page 23
Page 24
8. Adjustments
If the <I/O> key is pressed, first the sensitivity step can be selected with the
<HOLD> key (small bars = low sensitivity; middle bars = middle sensitivity; large
bars = high sensitivity). After repeated pressing of the <I/O> key, the battery capacity is indicated. If only 4 bars (grey) are indicated, the capacity is still sufficient
for approx. 1 hour. With the help of the <HOLD> key the following adjustments
can be selected :
- without lighting/without acoustic signal
- with lighting/without acoustic signal
- without lighting/with acoustic signal
- with lighting/with acoustic signal
With the <I/O> key the selected adjustment is taken over and the adjustment
menu is left.
9. Switch off
Keep the <I/O> key pressed until all bars in display are gone.
10. Function control
Unscrew the cover cap of the testing bottle and hold
the sensor head over the opened bottle (see illustration). If the sensor is correct, the bar line display shows
a clear reaction. The sensor can be changed at
switched off instrument (unscrew sensor head - replace sensor element with a new sensor element mount sensor head).
