2 Preparations
Moisture meter for wood and building materials. The BYK m200
measures the moisture level for a variety of wood and building
materials. The meter also measures the ambient temperature &
humidity. The displayed value is material moisture in % with respect
to dry mass.
Example:
100% material moisture for 1 kg of wet wood = 500g water.)
IMPORTANT!
• Always keep the instrument dry
• Pay attention to the electrodes whenever the protective cap
is removed. They are sharp!
• Clean dirt and debris from the measuring electrodes
• Replace batteries when the battery warning symbol appears

5.0 MEASURING AMBIENT TEMPERATURE & HUMIDITY
The device measures the ambient temperature & relative humidity.
The ambient temperature is used as a temperature compensation
to increase the moisture accuracy. Press the “SET” key for about 2
seconds, the display will switch between temperature and humidity.
To can change the temperature units from °C to °F in the settings
menu, please refer to chapter 7.4.

6.0 MOISTURE MEASUREMENT MODE MENU
There are three measuring modes; you can switch among them by
pressing the “MODE” key.
Wood Mode: Building Mode: Self-Test Mode
W1, W2, W3 B1, B2, B3, B4
6.1 SELECT WOOD GROUP IN WOOD MODE (W1,W2,W3)
When the meter is turned on the Wood Mode is the default position.
There are three wood groups. You can switch among them by
pressing the “SET” key. To select the correct wood group(W1, W2 or
W3), find the wood you are measuring in Table 1.
Once you have selected the wood group proceed with the
measurement by inserting the pins into the sample. The % Moisture
is displayed. The two bar graphs also display the measured value. The
left side bar graph shows the maximum % moisture measurement.
The maximum measurement is retained on the display until the
“CLR” key is pressed or the instrument is powered off. The right side
bar graph is a graphical version of the digital % moisture value.

6.2 SELECT MATERIALS IN BUILDING MODE (B1,B2,B3,B4)
After you turn on the meter push the “MODE” key one time to select
the building mode. There are four building material groups, you can
switch among them by pressing the “SET” key. To select the correct
building group use Table 2 to find the material you are measuring

For building materials from group B05 through B15 the Wet/Moist/
Dry indicator function has to be used to measure the % moisture
(refer to section 6.3).

6.3 WET/MOIST/DRY INDICATOR
The wet/moist/dry indicator is displayed for evaluating the moisture
of materials B05 through B15 in Table 2. The moisture level is divided
into DRY, MOIST, WET grades. You can set the wet and dry threshold
values in the setting menu (refer to section 7.2). When measuring
a sample the indicator dot moves along the Dry/Moist/Wet scale.
To interpret the dot location to a % moisture value use Table 3. For
example, if the dot location is in the moist region and your building
material is a B06, the material moisture is between 0.9 – 1.2%.

(2) Connect electrodes with “T” contacts
located on the protective cap.
If the test is not approved – check the electrode pins for dirt or
damage. If the pins are damaged, replace the pins with new pins.
Please contact your BYK-Gardner representive if you need additional
assistance.

7.1 SET MATERIAL TEMPERATURE COMPENSATION
Relative material moisture is dependent on the temperature of
the material. The meter automatically compensates for material’s
temperature. The ambient temperature value is used for the
compensation calculation.
The ambient temperature can be manually adjusted to increase the
measurement accuracy. This value is not stored and must be re-set
each time the device is switched on. Press the “SET” key to increase
the value; the “CLR” key decreases the value. The value is saved when
the “MODE” key is pressed.

7 Settings
7.2 SET DRY/WET INDICATOR
The dry/moist/wet indicator is programmed from defined values.
The values may be changed as follows. The default “dry” threshold
value is 70 and the “wet” threshold value is 850. Press the “SET” key
to increase the value; the “CLR” key decreases the value. Press the
“MODE” key to sequence from the “Dry” setting screen to the “Wet”
screen. The values are saved by pressing the “MODE” key.
7.3 SET LCD BACKLIGHT MODE
The LED display illumination can be changed to:
AUTO: Display illumination switches off during periods of inactivity
and switches on automatically when in use.
ON: Display illumination remains on during use.
OFF: Display illumination remains off during use.
The ON/OFF settings are not stored when the meter is turned off.
The default is set to “AUTO” mode each time the device is switched
on. Press the “MODE” key to save the setting and sequence to the
“Set Temperature Units”

8.0 REPLACING BATTERIES
When the batteries drop below the operating voltage, the battery
warning symbol will appear; replace the batteries when the
warning symbol appears. The meter uses three (3) CR2032 coin style
batteries.
Unscrew the battery cover in the back of the meter.
Remove the battery cover. Change the batteries.
The positive side of the battery is in the up position at all three
locations. Re-attach the battery cover and tighten the screw to secure
the cover.
