Preparing for measurement
The time required for an official measurement is approx. 30 min.
If you switch to wood chips as fuel immediately following
a measurement using wood pellets or split logs as fuel, the
message
Particulate matter sensor and sensor cover
need to cool down (this process may take a few
minutes)
appears. Prior to selecting wood chips as fuel,
Testo recommends opening the particulate matter sensor
cover so that the sensor can cool down, . To shorten the
cooling down period, the sensor should be moved to a cold
environment or placed on a cold surface.
The
