compensation function. If the meter is used in
an ambient with a wide temperature
difference, please leave the meter to rest for
30 minutes until it has reached room
temperature.
For the best results, the probes should be
inserted perpendicular to the wood’s fibre
structure.
This meter has been calibrated before delivery.
Do not revise the calibration parameters
