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

(20

C). 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.
