device.
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. Moreover, 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.
Warning
High concentrations of combustible gases cause a risk
of explosion, fire and suffocation.
Make yourself familiar with the characteristics of the
gas to be detected and take the necessary precautions.

Operation
2,5h
Charging the battery
Warning of explosive substances
Never charge the battery in a potentially explosive
atmosphere.
Warning of electrical voltage
Before each use of the charger or power cable, check
for damages. If you notice damages, stop using the
charger or power cable!
Notice
The battery can be damaged in case of improper
charging.
Never charge the battery at ambient temperatures
below 10°C or above 40°C.
The battery is partially charged upon delivery to avoid damage
to the battery caused by a deep discharge.
The battery should be charged prior to initial start-up and when
the battery is low (battery indicator(17) flashes). To do so,
please proceed as follows:
1. Plug the charger into a properly fused mains socket.
3. Wait until the battery is fully charged(approx. 2.5 h).
4. If necessary, check whether the battery is fully charged by
switching the device on and checking the charging
indicator.
Switch-on
Info
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.
ð The device switches on.
ð An 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. 40seconds.
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.
ð The display shows a countdown from 40.
ð Once the calibration is completed, an acoustic signal is
emitted and the device briefly vibrates.
2. Connect the charging cable to the device connection.
ð If the device is switched on, a charging indicator will
appear on the display.
Info
You cannot make any further settings, such as
switching the vibration on or off, during calibration.

Measuring
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 10ppm upwards.
2. Move the sensor towards the suspected leak.
ð The current measurement result is shown by the
deflection on the scale and as a numeric value in ppm
and LEL.
ð If 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 >1000ppm
with the device.
4. If required, carry out a zero reset(AutoZero).
Setting the measuring range
1. Press the H/L button(7) to switch between the low(x10)
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.
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).
ð The 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.
Automatic switch-off
If the Automatic switch-off indication(16) is displayed, the
device will switch off automatically when not in use for approx.
10 minutes.
To deactivate automatic switch-off, please proceed as follows:
1. Press the Automatic switch-off button(8).
ð The Automatic switch-off indication(16) disappears.
ð Automatic switch-off is deactivated.
Repeat these steps to switch automatic switch-off back on.
Switching the device off
1. Press the Power button(11) for approx. 2s.
ð A brief acoustic signal is emitted.
ð The device switches 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.
