Check and Change Settings
Settings for wood species are listed
on the laminated pocket guide in-
cluded with each meter. To recall ac-
tive settings push the SET/HOLD key.
As long as the screen shown below
appears, you can use the
or
keys to change settings.
Change mm to inches:
Disconnect
battery and press SET key twice.
Connect battery again. The display
pictured below will appear, push
key to change from inches to mm
and push
key to change from
mm to inches.
3.24 is the software version.

Ligno-Scanners S or D
The Scanners S or D are capacitance-
type meters for wood, bamboo and
building materials. The sensor plates
on the back emit and pick-up very low-
powered electromagnetic signals.
The readings generated by the Ligno-
Scanners are average values of the
entire measuring field between the sur-
face and the maximum depth of pen-
etration. Moisture closer to the sur-
face has a greater effect on the aver-
age than the moisture closer to the
maximum depth of penetration.
All Lignomat meters internally check
and adjust the calibration. Therefore
manual recalibration is neither needed
nor possible.
Wood:
Range: 5*-60%. Readings
above 25% fiber saturation point are
less accurate. *To check the lowest
possible reading, hold the meter in
the air and push the READ key. The
range for hardwoods (softwoods)
with high (low) specific gravity is lower
(higher) than 5%.

Take Measurements
After settings have been checked /
changed, push the READ key to ob-
tain moisture readings. The active
setting appears
briefly, followed
by the default
(lowest) reading, if the sensor plates
are not in contact with any material.
For actual measurements, place the
meter on the
test sample (for
wood in the di-
rection of the grain). Press down
slightly, holding the outer sides of
the meter without touching sample
with your hand.
The HOLD key is
used to freeze
the indicated value for one minute.
Helpful when taking notes or when
measuring in places, where the dis-
play cannot be read while measur-
ing. At any time you can switch back
to measuring by pushing the READ
key again.

Settings: 30-100.
Gravity Range 0.3 to1.0. For unlisted
species the specific gravity can be
entered as species setting. For ex-
ample, if the specific gravity is 0.42
the setting is #42. Values for the spe-
cific gravity can be found on the
Internet by entering <specific grav-
ity...> followed by the name of the
wood. For calculations see section F1.
For unlisted species or new products
Lignomat offers testing to determine
the correct setting.

Measuring Depth:
Ligno Scanner S 1/4" (7mm)
Ligno-Scanner D 3/4" (20mm)
Battery: One 9V battery (included). To
exchange the batter y, slide batter y
cover off on back of instrument. A low
battery symbol will appear on the dis-
play, when the battery has been drained
to 25% of its capacity.
B2
When the moisture is too low to mea-
sure, the default reading appears with
"Min" in the lower left side of the
display. When
the moisture is
too high, the
highest moisture value is displayed
with "Max" on the lower left side of
the display.
For accurate readings:
- Sample should be big enough to
cover both sensor plates
- Measuring depth has to be set
according to sample thickness.
- Surface should be smooth and
flat. For uneven surfaces take
the highest value of several
measurements.
To eliminate any possible influence
from material underneath the sample
board, it is recommended (if pos-
sible) to arrange the sample so that
an open space is directly underneath
the measuring area. If this is not pos-
sible, make sure the Ligno-Scanner
SD is set for the correct measuring
depth.
