Operation
Switch-on
Switch detector on in fresh air since the sensor is initialised when
switched on
Readiness to operate is indicated by an audible signal.
Detecing leaks
Position the detector such that the sensor opening (orange) is
purged by the ambient air in the area under scrutiny. Avoid
covering the surface of the sensor.
- The 8 bar symbols change to black according to the concen-
trations detected and the frequency of the audible signal rises
with increasing gas concentrations.
- If the alarm value is exceeded, a continuous tone is emitted
and the alarm symbol ( ) lights up.
