９．NOTES FOR THE MEASUREMENT
The electric resistance type Moisture meter utilizes the characteristics that the electric characteristics of
an object to be measured reacts specially sensitively on its moisture contents, but the relation is not
perfectly related in one-to-one ratio.
When its composition and proportion are different or change in quality and contamination exist or special
processing and chemical treatment are performed even though the same object, it is necessary to avoid the
measurement at these places or to use the measured values after compensating.

⑰
, the batteries close to
the limit of use due to consumption.
Open the battery case
⑲
by sliding the cover downward
and replace all alkaline batteries R6P(1.5V) × 8 pcs.
with new ones. (ensure the limit of use.)
When the Meter is continuously used after voltage
drop mark [E] was indicated on the LCD display,
following conditions will occur.
・
Though it differs depending on the characteristic and using condition of the dry batteries,
the Meter can work for several hours.
(Replace all 4 batteries with fresh specified dry batteries earlier.)
・
When the Meter is continuously used as it is, measured values will become unstable.
・
When the power switch is turned ON, the buzzer continuously sounds and key operation become
impossible simultaneously.
(Remove the batteries from the Meter.)
・
When no indication is on the LCD display, the batteries are completely consumed.

Handling while the Meter is not in use
・
Even if the power switch
①
OFF, the battery capacity has been slightly consumed.
・
In case the Meter will be not used for 1 month or more, it is recommended to store the Meter after
removing the batteries from the case.
１１．MAINTENANCE AND INSPECTION
・
Wipe dirt off with soft cloths, etc. after using the Meter.
Specially care to keep the probe connector, electrodes, groove between electrodes, etc. clean and dry.
・
Prevent the Meter from exposing to shock, direct sunlight, high temperature, high humidity, etc.
・
Select a dust free, clean and well-dried place for storing the Meter.
In case the Meter will be not used for 1 month or more, remove the batteries from the Meter.
・
Carry out the periodically inspection and calibration to keep the efficiency of the Meter.
