
If the concentration remains unchanged, the deflection moves back to
the centre. The deflection is reset manually using the
[--> 0 <--] key
Carrying out the measurement
1
Move the sensor head as close as possible and at low speed (approx.
< 2 cm per second) over the components that are to be checked for
leaks.
The surface of the sensor must not be covered.



Concentration < 100 ppm: The sensor LED and the display
illumination light up green. In addition, the bar display increases.

Concentration > 100 and < 999 ppm: The sensor LED and the
display illumination light up yellow. In addition, the bar display
increases.

Concentration > 999 ppm: The unit changes to VOL% and the bar
display increases.

Concentration > 9999 ppm / > 0.99 VOL%: The sensor LED and the
display light up red (alarm threshold).


When the lower explosive limit is reached, ">LEL" is displayed. Higher
values are not displayed.
To locate the leak, it is advisable, in the case of these larger leaks, to
switch to
MODE 2 in order to receive feedback via audio and flashing
signals.


If the warning threshold (100 ppm) is exceeded, the sensor LED and
display illumination light up yellow. If the acoustic alarm is enabled, an
additional warning sound is emitted when the warning threshold is
exceeded, the frequency of which increases as the concentration
increases, and changes to a continuous tone when the second alarm
threshold (10,000 ppm) is exceeded.
Changing units
By default, the display shows ppm (concentration in parts per million). From a
concentration of >999 ppm, the display changes to vol% (1000 ppm=0.1 vol%).
Higher concentrations in ppm are also displayed in the app.
In addition, %LEL (the percentage of the lower explosive limit that has been
reached) can be selected.
1 Press the unit key to change the unit.
Carrying out manual zeroing
The zero point can only be set manually if the currently detected gas
concentration is below the max. 250 ppm (max. 250 ppm can be suppressed).
For example:

150 ppm (≤ 250 ppm): are completely suppressed (display: 0 ppm)
