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,
