TG-S: Soft wood TG-H: Hard wood Mo: Mortar and Concrete
P ℓ: Plaster KG: Paper MC-S: Moisture comparison mode
・The measurement mode is converted each press of the「G」key ② as follows.
TG-S → TG-H → Mo → P ℓ → KG → MC-S
・The selected mode is indicated in the upper part of the LCD display ⑥.
・When power ON again after power OFF once, the mode will automatically return back to
the［ TG-S ］mode.
・Be sure to confirm the mode when the measurement is carried out.
4-3 Converting the hold mode
・When the「HOLD」key ④ is pressed, the［ HOLD ］is indicated in the lower right part of the
LCD display ⑥ and the mode is switched over to the hold mode.
The indicated measured value will be held until the next measurement.
・The holding function of the measured value is released by pressing the「HOLD」key ④ again and
the indicated［ HOLD ］on the LCD ⑥ disappears.
4-4 Converting the key lock mode
・When the「LOCK」key ⑤ is pressed, all keys except the 「POWER」key ① are locked and
misoperation can be prevented.
The key lock mode is released by turning the power OFF.
4-5 Measurement
・Stab the 2 needle electrode ⑦ into an object to be measured and read the indicated value after
settlement of the indication.
・When the needle electrode can not be used to an object to be measured, use the attached conductive
rubber electrode ⑩ insertinginthe2electrodepart⑦. (Same for paper, mortar/concrete and plaster)
When the electrode is loose, tighten by turning the side screw with the hexagonal wrench.
・When the measured value exceeds or under the measuring range,［LLL］or［HHH］is indicated
on the LCD display.
4-6AutopowerOFF
・When new measured values are not inputted for about 3 minutes or more, the Meter is automatically
power OFF to prevent the consumption of the battery.
・When the electrode part ⑦ is contacting with an object to be measured, auto power OFF function may
not work occasionally.

５．TEMPERATURE COMPENSATION
The automatic temperature compensating function is set ON at the initial setting condition of the Meter
and the indicated values is automatically temperature
Ex: In case the temperature
compensated based on 20 ℃. compensation is set OFF
ON or OFF of the automatic temperature compensating function
is converted by pressing the「℃」key ③.
When this function is set ON, the［ ℃ ] is indicated on
the LCD display ⑥ and is not indicated in case of setting OFF.
When the automatic temperature compensating function is set OFF, refer to the following list for
the temperature compensation.

６．NOTES FOR THE MEASUREMENT
Measuring values may disperse according to measuring circumstances.
Electric Resistor Type Moisture meters use the applications of sensitively electric characteristics of
measuring objects against the moisture contents and the corresponding relations never be a perfectly
correlative one-to-one.
In case of measurinf with different compositions ･ combinations, albeit the same material, and with
changes in quality, salt, contamination, and furthermore with special processing, chemical treatments,
it may be necessary to avert measuring such unfavorable objects, and compensate or average
measured values. As for compensating, it is in general, based on moisture measurement methods
in accordance with a drying process.
７．BATTERY
7-1 Indication of the voltage drop
When [ BAT ] showing the voltage drop is indicated
in the lower left of the LCD display ⑥, the batteries
close to the limit of use due to consumption.
・ Open the battery case on back side by sliding the lid ⑨
sideward, take out the battery case of the Meter taking care
the wiring and replace all alkaline dry batteries LR03(1.5V)
2 pcs. with new ones. (ensure the limit of use).
When the Meter is continuously used after voltage drop mark
[ BAT ] was indicated on the LCD display, following
condition will occur.
・Though it differs depending on the characteristics and
using condition of the dry batteries, the Meter can work for several hours.
(Replace all 2 batteries with fresh ones earlier.)
・When the Meter is continuously used as it is, measured values will become unstable.
・When the「POWER」key 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.
7-2 Handling while the Meter is not in use
・Even if the「POWER」key OFF, the battey 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.
８．MAINTENANCE AND INSPECTION
・Wipe dirt off with soft cloths, etc. after using the Meter.
Specially care to keep the electrodes and groove between the 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.

９．M ISCELLANEOUS
9-1 How to use the Moisture reading checker(option).
Press the electrode against the checker as shown in the following sketch in power ON condition.
When the reading of the Meter matches the figure on the checker, the Meter's reading is acceptable.
When the reading deviates from the checker's, please request our agent or the nearest our branch to
calibrate the Meter.
※ An object for checking by the Moisture reading checker differs the face side from the back side.
Use after surely confirming model, type of the Meter and measurement mode.
※ When checking the Meter, carry out after turning the temperature compensating function OFF.
Refer to " 5. TEMPERATURE COMPENSATION " in detail.
9-2 Cover for the needle electrode(Fitting/removing methods of the cover)
Fit the cover in the needle electrode spreading out by fingers holding both sides of the cover for
the electrode.
When the cover is tight, fit by force prying it.
Carry out the same procedure for removing the cover.
Fitting/removing the cover by force causes au injury occaisionally.
Be careful not to be injured with the Needle electrode
