4. MEASURING PROCEDURE
If the test pins ( 3-7, Fig. 1 ) are not installed to the
probe head & packed separately, please refer the
following diagram to fix the test pins into the probe.
4-1 Measurement by selecting the different
material
1)Power on the meter by pushing the " Power button "
( 3-3, Fig. 1 ).
Remove the " Protection cover " ( 3-8, Fig. 1 ) away
from the " Test Pins " ( 3-7, Fig. 1 )
2)Press the" Material button " ( 3-6, Fig. 1 ) to select the
desired testing material.
Material 1 :
* 0 to 100% relative moisture value for
Concrete. and other non-wood material.
*
The right bottom display show " 1 "
Material 2 :
* 6 % to 40 % moisture range on wood.
*
The right bottom display show " 2 "

3)It is recommended that the test pins are inserted to a
minimum depth of 2 mm into the material under test.
If a depth of 2 mm can not be obtained, then insert the
test pins to their maximum achievable depth.
Fig. 2
4)Display will show the moisture contents in " %
moisture content " directly.
Consideration :
If the sample under test has a high moisture
content it may take a few minutes to obtain a
stable reading.

4-2 Other Functions
1)Data Hold
* During measurement, pushing the " Hold button "
( 3-4, Fig. 1 ) will hold the display values & the LCD
will show the " D.H " symbol.
* To cancel the Data Hold function, Press the
" Hold button " once more.
2)Data Record
* The data record function records the maximum and
minimum readings. Press the " REC Button " ( 3-5,
Fig. 1 ) once to start the Data Record function. "
REC " will be displayed.
* With the " REC " symbol on the display :
a)Press the " REC Button " ( 3-5, Fig. 1 ) once, the "
REC MAX. " symbol along with the maximum value
will appear on the display.
To delete the maximum value, just press the " Hold
Button " ( 3-4, Fig. 1 ) once. The display will show
" REC " and execute the memory function
continuously.
b)Press the " REC Button" ( 3-5, Fig. 1 ) again, the
REC MIN. " symbol along with the minimum value
will appear on the display. To delete the minimum
value, just press the" Hold Button" ( 3-4, Fig. l )
once, then the display will show the " REC " symbol
only and execute the memory function continuously.
c)To exit the memory record function, just press the
REC" button for at least 2 seconds. The display will
revert to the current reading.

4-3 Optional separate probe
If intend to use the sperate probe to make the moisture
measurement, just prepare the separate probe ( MP-31,
optional, 3-13, Fig. 1 ) and connect the probe plug into
the " Input socket " ( 3-10, Fig. 1 )
5. MAINTENANCE
5-1 Replacement of Battery
A low battery is indicated by " " in the left corner of
the display. To replace the battery remove the battery
cover with a small screwdriver or coin and replace with a
DC 9 V battery ( heavy duty type, 006P, MN1604/PP3 or
equivalent ).
5-2 Replacement of test pins
To replace test pins on the probe, first loosen the lock
nut at the base of the pin, slide pin out and replace with
new.
