Merlin HM9 Manuel D'utilisation page 78

Uneven wood, wood which is narrower than
the sensor surface, or wood which is thinner
than the minimum wood thickness cannot be
measured.
Depending on the HM9 model, the measur-
ing surface and depth of your moisture meter
differ.
The specimens must have the following mini-
mum size and material thickness:
Model
WS1
WS5
WS13
WS25
DUO 5
DUO 25
Note: If the specified values are undercut,
fault-free measurement is not possible.
• The measuring surface must always be
covered entirely by the specimen.
• The measuring surface must be applied
evenly on the specimen.
