6.2.1. 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. Testo recommends opening the
particulate matter sensor cover prior to selecting wood
chips as fuel, so that the sensor can cool down, see
Cleaning/replacing the sensor module, page 64. To shorten
the cooling down period, the sensor should be moved to a
cold environment or placed on a cold surface.
