FUKTKVOTSMÄTARE
BRUKSANVISNING MC-400
INTRODUKTION
MC- 400 är ett mätinstrument för noggranna mätningar av fuktkvoten i trämaterial och är förprogrammerad
med materialkoder för olika träslag, kompensering för materialets temperatur samt testfunktion för att
kontrollera fuktkvotsmätarens kalibrering. MC-400 levereras i två versioner komplett med väska:
MC-400A MC-400B
• Mätsond för trä (S-10)
• Anslutningskabel 1,2 m
• Mätstift för S-10:
- Stål (mätdjup: 12/19/26 mm)
• Hammarelektrod (S-30)
• Anslutningskabel 1,2 m
• Mätstift för S-30:
- Teonbelagda (mätdjup: 30 mm)
Extra tillbehör:
- S-10 Mätsond
- S-30 Slaghammare
- Mätelektroder för ytmätningar. (Fanér)
- Referensmotstånd
Mätstift för S-10
- Stål (mätdjup: 12/19/26 mm)
- Stål (mätdjup: 56 mm)
Mätstift för S-30
- Teonbelagda (mätdjup: 45 mm)
- Teonbelagda (mätdjup: 30 mm)
HANDHAVANDE
Anslut sladden från hammarelektroden till mätinstrumentet.
Välj typ av virke, vridomkopplare ”Wood group” i läge 1 - 4. Se ”Tabell - Trägrupper” i slutet av
bruksanvisningen.
Kompensera för virkets temperatur, vridomkopplare ”x 10 oC”. (Se även avsnittet för
”Temperaturkompensation” nedan).
Slå in hammarelektrodens mätstift i virket till det djup på vilket fuktkvoten skall mätas (1/3 av virkets
tjocklek är vanligast). Undvik kvistar och ådring.
Läs av mätvärdet efter 3 - 5 sekunder.
Upprepa punkt 4 och 5 för nya mätpunkter.
Ställ vridomkopplaren för materialinställning ”Wood group” i läge ”0” (Off) när mätningarna har avslutats.
ATT BEAKTA VID MÄTNINGAR
• Mät alltid i era mätpunkter. Det är osäkert om mätvärdet i en mätpunkt kan representera fuktkvoten i
virkets hela volym.
• Kontrollera att stiftelektroderna är hela och ordentligt fastskruvade.
• Hammarelektrodens mätstift skall slås in vinkelrätt mot ådringen.
• Undvik att slå mätstiften i kvistar och ådringar.
• Erhållet mätresultat gäller endast för den punkt och på det djup som hammarelektrodens mätstift har
slagits in.
• Läs av mätinstrumentet efter 3-5 sekunder.
• Mätinstrument och hammarelektrod skall förvaras i torr miljö (-20 till +60 oC).
TEMPERATURKOMPENSATION
Fukthalten i trät påverkas i hög grad av materialtemperaturen och därför är det viktigt att ställa in
temperaturkompensationen genom att ställa vridomkopplaren ”x 10 oC” till rätt värde.
Vid temperaturer mellan ovan angivna fasta lägen läses fuktkvoten av vid temperaturen närmast över och
under och därefter väljs ett medelvärde.

FUKTKVOTSMÄTARE/MOISTURE CONTENT METER
WOOD GROUP TABLE MC-400
INTRODUCTION
MC-400 is a measuring device for accurate measurements of Moisture Content in wood and is programmed
for different kinds of wood. The measurement can be temperature compensated. A quick reference guide is
mounted on the backside of the meter.
MC-400 is delivered in two versions:
MC-400A MC-400B
• Measuring probe for wood (S-10)
• Connection cable 1,2 m
• Electrodes for the S-10 probe:
- Steel (Measuring depth: 12/19/26 mm)
• Sliding hammer (S-30)
• Connection Cable 1,2 m
• Electrodes for the S-30 probe:
- Teoninsulated (measuring depth: 30 mm)
Accessoirs:
- S-10 Measuring probe
- S-30 Sliding hammer
- Surface Electrodes for surface
measurments
- Reference resistors
Electrodes for S-10
- Steel (: 12/19/26/56 mm)
Electrodes for S-30
- Teoninsulated (measuring depth: 45 mm)
- Teoninsulated (measuring depth: 30 mm)
SWITCH THE UNIT ON/OFF
The wood group correction switch is at the same time the ON/OFF-switch (Position ”OFF“ – unit is switched
off).
Once set a wood type, the unit is automatically in operation.
WOOD GROUP SELECTION
To achieve the best possible measurement accuracy use the wood type selector (wood group correcting
switch). It should be set to the appropriate wood group before any measurements are taken. The Wood
Group Correction Table is found on page 4-6.
As far as the majority of European and exotic timbers are concerned the table indicates which wood group
they belong to. For European woods not listed in the table, wood group 3 should be selected.
The optimum setting for types of wood which are new on the market or as yet unknown should be determined
by test measurements and oven-dry tests until constant weight is achieved.
TEMPERATURE COMPENSATION
When measuring Moisture Content in wood the accuracy is inuenced by the material temperature. Use
the temperature compensation knob marked “x 10°C“ to set the appropriate wood temperature value. The
measured value is automatically corrected when it is displayed.
The MC-400 unit has an automatic electronic calibration function no additional calibration is needed.
It is advisable to check if the electrodes are dirty. The plastic part of the electrode should be cleaned in order
to prevent accumulation of surface dirt. Use alcohol as a cleaning agent. Other detergents or solutions may
lead to a reduction in insulation.
POWER SUPPLY
The MC-400 is equipped with 9 Volt alkaline block battery. Up to 30.000 measurements can be made with
one battery. It is located in battery box on the back of the unit and may be replaced with any commercially
available 9 Volt battery of the same size. However, only leak-proof batteries should be used, since if any
vapors were to escape they could damage the electronic circuits.
BATTERY CONTROL
To guarantee an excellent consistence of measurements for all built-in stabilizing and compensation circuits,

it is necessary to prevent battery voltage from falling below the minimum permitted.
For this reason, the MC-400 is equipped with the following control-elements:
• If battery voltage falls below the minimum permitted an early warning system will display ”Low Batt:.“ or
will show – depending on the system chosen – an arrow on left top of the display.
Nevertheless it is still possible to take measurements with undiminished accuracy – approx. a few hundreds
more – it is advisable to replace the battery now. This is to avoid a total black-out of the value indication.
REPLACEMENT OF BATTERY
Open the battery box on the back of the unit and replace the battery.
How to use instrument:
Connect the probe (S-10 or S-30) to the instrument using the connection cable.
Determine what wood specie and select appropriate „Wood Group“ 1 - 4. See ”Table - Wood group” in
the end of the manual.
Set the temperature compensation of the wood with ”x 10 oC”. (See ”Temperature Compensation“
below).
Insert the electrodes in the timber to the wanted measuring depth (usual 1/3 of the total thickness. Avoid
twigs.
Read the measurement value after 3-5 seconds.
Repeat 4 and 5 for new measurements.
Set the ”Wood group” knob to ”0” (Off) to turn off the meter.
NOTE:
• Always measure several measuring points. It is not certain that a single measurement point is
representative for the complete timber volume.
• Check that the electrodes are not bent and securely tightened to the probe.
• The electrodes shall be inserted crosswise the grain.
• Avoid twigs.
• The measuring result is only valid for the measuring point and the penetration depth that electrodes
are inserted to.
TEMPERATURE COMPENSATION
The moisture content is affected by the material temperature. It is important to set the appropriate correction
value using the knob ”x 10 oC”. If the temperature is in between the scale settings a measurement is made
on the nearest above and one nearest below temperature. The correct value is the mean value of the two
measurements.
BATTERY CHECK
If the battery voltage is below normal level ”Low Batt” or an arrow is indicated in the display the battery
needs to be replaced immediately to ensure correct measurements.

CONTROL USING REFERENCE RESISTORS (Option)
There are two reference resistors available as an option. Normally no adjustment is necessary. If the values
deviates from the tolerance the instruments needs to be sent for repair.
INSTRUCTION:
Set the meter to +20º C.
Set the woodgroup to No. 3.
Insert the appropriate resistor in the instrument.
Compare the reading with the value and tolerance in the table below.
The value should not deviate more than the dened tolerance.
