Brief instructions
Important notice: The detailed operating ins-
tructions must always be observed for all de-
tails, e.g. light or signal ON/OFF , calibrations
or charging the device.
Switching on by pressing this button (only in
a gas-free atmosphere). After switching on,
the LCD display flashes H2 and HEAt alterna-
tely for the duration of the approx. 50 second
long heat-up phase. The analogue bar at the
lower edge of the display builds up from left
to right.
The display shows 0 ppm after the heat-up
phase is completed. Measurements can now
be made.

When a concentration is measured, the dis-
play first increases to 999 ppm and when it
reaches 0.1% it switches to the vol% measu-
ring range. The LEL message occurs at over
4.0 vol%. This is reinforced by a continuous
tone. The display and signal cannot be stop-
ped, even by switching to "clean air" . The
device should be switched off in a gas-free
atmosphere.
Warning: A gas report with LEL and a conti-
nuous tone may indicate an explosive gas-
air mixture.
To switch off: Press and hold the ON/OFF
button for 2 seconds.
