Charging the rechargeable battery:
See chapter “First steps”
Cleaning the sensor:
Tobacco smoke, dirty air, oils, grease, silicones and evaporating liquids or gases can
lead to deposits on the surface of the sensor. This can result in reduced sensitivity
and falsified display of concentrations. If necessary clean the sensor.
> Switch on the instrument, wait until the end of the initialization phase and switch
off again. Repeat this procedure several times.
Clean the sensor head from the outside
> If dirty, clean the sensor head with a soft dry cloth.
Cleaning the housing:
> If dirty, clean the housing with a damp cloth (soap solution). Do not use aggressive
cleaning products or solvents!
Switching on regularly
If the instrument is used infrequently, deposits may build up on the sensor.
Switching the instrument on prevents deposits building up on the sensor. Testo
recommends switching the instrument on regularly to avoid deposits building up
on the sensor.
Storage & transportation
To avoid contamination of the sensor, the instrument should not be stored
or transported in an environment where there is tobacco smoke, foul air, oils,
greases, silicones or evaporating liquids or gases. Any sensor that is contaminated
as a result of storage or transportation must be cleaned before use, see Cleaning
the sensor.
Regular servicing:
Testo recommends yearly servicing of the gas detector by an authorized service
centre.
