User Instructions for all mini-Lignos

Before taking measurements with a mini-Ligno, the
protective cap over the pins has to be removed
and can be placed on the other end of the meter
for easy pin insertion. As soon as the pins are
pushed into the wood, the on-off switch between
the pins is depressed. Red LEDs indicate wood
moisture in percent for a wood temperature of
70

0F

(200C). For higher or lower wood tempe-

ratures see correction table on page 6

All Lignomat meters internally check and adjust the
calibration. Therefore manual checks and
recalibration is not necessary and not possible.

Wood Group Corrections:

All mini-Lignos are

equipped with built-in wood group corrections. A
chart for wood species and corresponding wood
group settings is included with each mini-Ligno.
Wood species with similar electrical properties are
in the same wood group. For unlisted wood species
Lignomat offers free of charge testing to determine
the wood group.

Core Measurements: For core measurements at
least one third of the wood needs to be penetrated.
The longer mini-Ligno pins reach 7/16”(10mm)
deep into a board. For core measurements in over
5/4” (30mm) lumber, make a fresh cut. Measure
the end grain close to the surface and at the core.
If it is not feasible to cut the board, the core of the
wood can only be reached with the external Electrode
E12 and any mini-Ligno C-model.

Battery: One 9-Volt Battery. If the LED lights get

dim or step 1 and 2 described under “Performance
Test” fail, remove screw on back cover, open-up
into 2 halves and replace battery.

Pins: All mini-Lignos come with 2 sets of pins #MA for
a measuring depth of 3/16” (5mm) and #MB for
7/16” (10mm). To exchange pins, remove screw on
back cover, open-up into 2 halves. The longer pins
are stored inside the back cover on either side of the
indentations for the pins. Remove and replace pins.

Electro-Magnetic Interference and Static
Electricity: If you measure close to computers,

power tools or electrical wires, several LED lights
may be on or the moisture readings jump. To avoid
the interference, take readings in a different location.
The wood, the meter and the person holding the
meter should not move while taking readings.

Performance Tests:
Step 1:

When the on-off switch is pressed by hand

without touching the pins, the lowest moisture value
is indicated: for mini-Ligno DX or DX/C: 5%
for mini-Ligno, mini-Ligno C, E/D, S/D or S/DC: 6%.

Step 2:

When the on-off switch is depressed by

hand and both pins are touched with two fingers at
the same time at least 12% should be indicated.

Step 3 optional:

Lignomat offers an external

testblock to check calibration and operation of any
Lignomat pin meter, including cable and electrode.
If steps 1, 2 or 3 fail either the battery needs to be
replaced or the meter is defective.

Mini-Lignos MD/C, S/DC, DX/C have two integral pins
and a cable connection built-in. To measure connect

cable ends into the
inserts besides the
pins. Depress on-off
switch between pins by
hand to activate meter.

Electrodes for mini C-Models

E12 Electrode and mini-BNC Cable is for
measure- ments up to 2” (50mm) deep in wood
and soft building materials (drywall, gypsum,
plaster, etc.) Allows comparing surface and core
moisture.

E14M Inspector Electrode: in-Hand probe
includes cable, EG Pins, teflon-coated. Measures
hard to reach places easily, because of its slim
shape. Extendable handle. Optional EL Pins 7”.

E16 Specialty/Concrete Electrode and
mini-E16 Cable for measurements of concrete

and other hard building materials. Standard pins
5/8” (15mm). Optional add EL Pins 7” (17.5cm)

In-kiln - remote

In-Kiln PK Probes and
mini-PK Cables

are used
for measure-ments of
stacked lumber in kilns,
air-drying yards or
warehouses. PK Probes
are available to measure
up to 2.75” deep. Cables
can be upon request up
to 50ft (15m) long.

Non-Kiln Applications

Lignomat’s cable system works well for monitoring inaccessible areas
(underside of floor planks, structural components, behind drywall,
roof trusses, etc.)
Teflon coated pins for a measuring depth of 3/4” and 7” are also
available. For those applications cables with loops are available.
