Regular inspection
Testo recommends having the gas leak detector inspected by an authorized
service centre every year.
8.3 Cleaning the sensor
Tobacco smoke, dirty air, oils, greases, silicones and evaporating liquids or
gases can leave deposits on the sensor surface. Possible consequences are
reduced sensitivity, distorted displays of gas concentration or display of a
background concentration. Clean the sensor if necessary
1
Switch on the instrument, allow it to initialize and then switch it off.
Repeat this procedure several times.
2
If it is dirty, clean the sensor head with a soft, dry cloth.
Switching on regularly
If the instrument is used infrequently, deposits may build up on the sensor.
Switching the instrument on prevents these deposits from building up on the
sensor. Testo recommends switching the instrument on regularly to avoid
deposits building up on the sensor.
Changing the sensor head
The instrument has a permanently installed sensor head that can only be
replaced by Testo Customer Service.
