This tester adopts the auto power off
function. The power of the tester is
automatically turned o in approx.
5 minutes after turning on the power if

Meanings of special marks The display may show marks as follows:
Battery mark Caution Battery is dead. Replace the batteries with new ones.
(displayed immediately after pressing the power switch and while using)
Over mark Caution Displayed when the measured result exceeded the upper limit of the
measurement range
Under mark Caution
Displayed when the measured result fell below the lower limit of the
measurement range, or the contact between the test sample tray
and the measuring unit of the main body was poor.
Error mark
Main unit temperature is too low -5°C or lower.
Main unit temperature is too high 50°C or higher.
• When measurement is performed with the Sample tray empty or the measuring unit is
poorly insulated due to condensation, high humidity, contamination, etc., the over mark,
under mark, or other meaningless numbers may be displayed. In such a case, clean the
measuring unit and dry it well in a natural way.

Measurement
Evenly in one layer on the sample tray
Put the test sample evenly in one
layer on the sample tray.
Note: Both the amount of sample is too
much or insufficient may cause a
measurement error. Over more, too
much sample may cause wear on the
screw and damage the instrument.
Note: Sort out immature or dead grains from
the sample tray in order to avoid error.

Rotate the handle counterclockwise
to let the sample tray enter the
testing chamber and insert it into the
testing chamber until the guide line
is hidden.
Note: Failure to observe this may cause the
tip of the handle to damage the plastic
portion of the sample tray. Be sure to
fully insert the tray.

Measurement
After a lapse of 5 minutes, the power
is automatically turned o and all the
displayed items are cleared.
Pressing the "POWER" button while
the display is in the on state allows

Pressing the "AVG." button after several
measurements can obtain the average
value of the measured moisture
contents. The average value calculated
from the measured values of the
measuring count 2 to 9 is displayed with
the average characters and number of
measurement times.
Note1: To obtain the average value of
moisture contents, press the
"AVG." button within 5 minutes
after measurement. After the last
measured value disappears, the
average calculation function does
not work.
The initial state is restored in the
following states:
• When the power is turned o
• When the "SELECT" button is pressed
• When the "AVG." button is pressed
• When the continuous measurement
count exceeds 9
Note 2: AVG characters are displayed while
an average value is displayed.
