Information about the device
Device description
The device BG40 detects the following combustible and/or
unwanted gases: natural gas, methane, ethane, propane,
butane, acetone, alcohol, ammonia, water vapour, petrol,
turbine fuel, hydrogen sulphide, smoke, industrial solvents,
paint thinners, naphtha.
The measuring device is able to detect gas concentrations of as
low as 10% LEL(Lower Explosion Limit) and warns the user via
both a visual and an acoustic alarm. The flexible gooseneck
allows you to easily reach poorly accessible locations.
Definition of LEL
• LEL = Lower Explosion Limit
The LEL of a combustible gas is the minimum concentration of
this gas at which the gas can start to burn when exposed to a
source of ignition (e.g. a match). At concentrations below the
LEL, the gas does not burn. Gas detectors for combustible gases
are generally calibrated for 0 – 100% LEL.

rear of the device is in your local language, if not, paste the
proper one over it. The warning sign is supplied along with the
device in several languages. Please proceed as follows to attach
the warning sign to the rear of the device:
1. Remove the label in your local language from the supplied
film.
2. Affix the label in the intended position at the rear of the
device.
Switch-on
Note
Chemical cleaning agents often contain solvents and
alcohols to which the appliance may react. It is not
possible to avoid this cross-sensitivity which can lead
to misleading results. For this reason, remove chemical
cleaners from the detection area of the device prior to
performing a leak detection.
Info
Please note that moving from a cold area to a warm
area can lead to condensation forming on the device's
circuit board. This physical and unavoidable effect can
falsify the measurement. In this case, the display
shows either no measured values or they are incorrect.
Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out
a measurement.
1. Press and hold the Power button(11) for approx. 3 s.
ðThe device switches on.
ðAn acoustic signal is emitted and the device briefly
vibrates.
2. After start-up, the device sensor is heated to operating
temperature and an automatic calibration with the local
gas concentration(s) is carried out simultaneously. This
process takes approx. 40seconds.
Due to this automatic calibration process, the device
should only be switched on in an environment that is free
from gases potentially affecting the measurement in order
not to distort later measurements.
ðThe display shows a countdown from 40.
ðOnce the calibration is completed, an acoustic signal is
emitted and the device briefly vibrates.
Info
You cannot make any further settings, such as
switching the vibration on or off, during calibration.
Carrying out a measurement
1. Use the H/L button(7) to set the measuring range to
low (x10) so that the device also indicates lower gas
concentrations from 10ppm upwards.
2. Move the sensor towards the suspected leak.
ðThe current measurement result is shown by the
deflection on the scale and as a numeric value in ppm
and LEL.
ðIf a higher gas concentration is detected, the frequency
of the acoustic and vibration alarm increases. For
further information on the alarm frequency, please refer
to the Technical data chapter.
3. If required, set the measuring range to high(x100) using
the H/L button(7) to visualize gas
concentrations >1000ppm with the device.
4. If required, carry out a zero reset(AutoZero).

and the high(x100) measuring range.
Switching the background illumination on or off
1. Press the Illumination button(9) to switch the background
illumination on or off.
Switching the acoustic alarm on or off
The acoustic alarm is enabled when the device is switched on.
The enabled acoustic alarm is indicated by the Alarm
indication(14) on the display.
1. Press the Alarm button(10) to switch the acoustic alarm
on or off.
Info
The function only refers to the sounds emitted when
the specified alarm thresholds are exceeded, not to the
button tones. The button tones cannot be turned off.
Switching the vibration alarm on or off
The vibration alarm is enabled when the device is switched on.
The enabled vibration alarm is indicated by the Vibration
indication(15) on the display.
1. Press the Vibration button(12) to switch the vibration
alarm on or off.
Zero reset (AutoZero)
This function serves to reset a measurement to zero. It resets
the calibration carried out at device start-up and adopts the
current concentration as the new zero.
This feature can be helpful in detecting leaks since it makes it
easier to locate the place with the highest gas concentration
and thus the potential point of leakage.
Before starting a new measurement with modified
environmental conditions, always carry out a zero reset in an
environment that is free from gases potentially affecting the
measurement.
1. Press the Zero reset button(13).
ðTheAutoZero indication(24) appears on the display.
2. Press the Zero reset button(13) again to disable zero reset.
Please note that the original calibration will not be
restored! For this purpose, you have to reset or restart the
device again.
