EIGER ALARM
The Geiger alarm is a discontinuous alarm, where the frequency is proportional to the
measured concentration.
8.2 E
XPLOSIVE RISK ALARM
The explosive risk alarm is a continuous alarm, which is set off when the measured
concentration is greater than or equal to the LEL of methane gas (44000 ppm, i.e. 4.4% gas).
The alarm is not configurable. For safety reasons, the user cannot mute or disable this alarm.

ALFUNCTIONING OF THE MEASURING ELEMENT
Some sensor defects are identified and displayed on the LCD matrix:
ERR00X with X = 1 - 7.
The error display is accompanied by an audio signal: two beeps at a frequency that increases
gradually.
The sound alarm can be cleared by pressing keypad key 5.
8.4 10,000-
PPM MEASURING RANGE OVERRUN
With the 10,000-ppm version of the Inspectra
Laser detector, the maximum displayed value
is 12,000 ppm. Beyond that concentration value, the measuring range is exceeded, leading to
the following:
- the display remains blocked on 12,000 ppm and the value flashes.
- the sound alarm is activated.
- the limit alarm LED is activated at the same time with the explosive risk alarm
LED.
