１．FEATURES AND APPLICATIONS

●The moisture contents for various materials/products can be measured with the probe connecting to the

instrument proper.

Kinds of the probe: probe for wood, probe for paper, probe for mortar and plaster

●The moisture contents of all kinds of objects can be compared in the MC mode.

Measurement can be carried out by converting the mode of the instrument proper keeping on each probe

connecting.

Select the probe to be connected in accordance with an electrical characteristic of an object to be

measured.

Classification and comparison of dry and moisture for the object can be easily and quickly checked as

these are displayed with values 1 to 100.

WOOD ：Sewn lumber, wood for buildings, fittings, packing, plywood, compiled wood,

particle board, wood for furniture, flooring, textile wood, wood works such as

household goods

PAPER ：Moisture control while storing and keeping of high quality paper, craft paper,

paper board, wall paper, corrugated paper, paper articles, used news paper,

used magazine, other used paper, etc.

MORTAR AND ：Moisture control of mortar, concrete, plaster, etc.

PLASTER Quality control for coating, clothing, tiling, all kinds of water proofing, etc.

MOISTURE ：Moisture control of fabric, food, chemical synthetic products, ceramic, etc.

CONTENT Moisture contents are indicated with a certain value, so that the object can be

judged by the comparison of the measured value.

a. Kind of the connecting probe

Display varies depending on the connecting probe and measurement mode as follows.

For Wood : TG-H, TG-S, MC-3

For Paper : KG, MC-2

For Mortar : MORTAR, PLASTER, MC-1

b. Setting of the communication with PC

When the communication function with PC is ON by the key operation, COM is displayed with the

selected communication speed.

This mark is erased in OFF condition.

c. Memory mode

When the memory mode such as storage or retrieve of the data to/from the memory is set,

Mem is displayed with the memory block number. When the no mode is set, this mark is not displayed.

d. Operation of printer

When the printer is in ON condition, Prt is displayed and not displayed in OFF condition.

e. Voltage drop of the instrument proper

When the voltage of the battery supplying the power to the electronic circuit of the instrument proper

drops until less than specific voltage, this mark is displayed.

When this mark is displayed, slide the cover of the battery space at the back side of the instrument

proper downwards and replace all four alkaline dry batteries for the control part of the instrument proper

placed in right hand with new ones quickly.
