CAUTIONS:

●Before using the Meter, read this INSTRUCTION MANUAL thoroughly

and use the Meter correctly.

●Keep this INSTRUCTION MANUAL carefully and refer to this, when

necessary.

●In the event of any doubt arising, the original INSTRUCTION MANUAL

in Japanese is to be final authority.

※Sensitivity of the probe of this Meter has been adjusted so as to

deal with the measurement of a thicker film thickness.

When the probe is left on a metal e.g. steel desk etc. the Meter may

indicate a certain value or「HHH」occasionally.

Before using the Meter, read this INSTRUCTION MANUAL thoroughly and use

the Meter correctly.

Keep this INSTRUCTION MANUAL carefully and refer to this, when necessary.

１．PRINCIPLE

When an iron is moved toward or away from

a steel core coil, self-inductance of the coil changes

in accordance with a slight changes of its distance.

This principle is utilized to measure the thickness (D)

of non-magnetic surface treated coating on iron substrate.

２．APPLICATIONS

The Meter is used for non-destructive measurement of the thickness of a non-conductive film such as coating,

lining, etc. applied to iron substrate including steel and ferritic stainless steel (SUS 430 etc).

The Meter can be applicable for various domestic and foreign standards and rules.

●Paints Machines, Appliances, Automobiles, Steel furniture, Bridges,

Ships, Cast iron tubes, Steel structures, etc.

●Linings Resin, Tar epoxy, Rubber, Enamel, etc.

●Platings Nonmagnetic platings such as Chrome, Zinc, Copper, Tin, Electroless nickel

excluding Electrolysis nickel plating

●Metallikon, Phosphoric acid film, Oxidation acid film, Spray deposit, etc.

●Resin film, Nonmagnetic metal foil

( Thickness is measured on the basis of a steel plate placed underneath of the film or foil.)

５．PREPARATION

5‑1． Preparation of the zero plate

Prepare the substrate which is the same kind, thickness and shape with an

object to be measured.

The attached zero plate for checking the Meter, SUS 430 Ferrite stainless

steel, is used for the operation check of the Meter.

Prepare the substrate of an actual object to be measured.

・Same kind The same kind of material as the substrate of an object to be measured

・Same thickness Nearly the same thickness as the substrate of an object to be measured

・Same shape The same shape in pipe diameter, curvature, geometrical shape, etc. as the

substrate of an object to be measured

・Size Substrate with an enough area on which the probe can be easily operated

・Surface condition Untreated (unoxidized etc.) substrate having smooth surface Remove rust,

dirt or dust, if any.

5‑2．Connecting(Disconnecting) the probe

Carry out the connection (disconnection) of the probe by the following procedures.

・Be sure to keep the Power OFF.

・The probe cannot be substituted with other probe.

UsetheprobewhichisthesamenumberwiththeMeternumber.

◎ Connecting method

Insert the probe into the probe

connector keeping the wide cut right

ward and tighten it by turning

Ａclockwise.

◎ Disconnecting method

Release by turning Ａ counter-clockwise

and calmly pull the probe out of

the connector.

Don't pull the cord as it

causes breaking of cord.

※When the probe is not connected to the Meter or any system is out of order even if the probe

is connected, the indication changes as follows after turning ON the power key.

If the probe is disconnected in power ON condition, 「PE」is indicated on the display and power

is automatically cut off. (｢PE」is abbreviation of Probe Error. )

Inside of the Meter is being initialized.

↓Keep the probe turn towards the air during this period.

↓←The buzzer emits a beeping sound.

The Meter is ready for measurement.

・When power ON, the last measured value of

the previous measurement is indicated.

・When the first power ON or all data are erased in the

statistical mode, [ −] is indicated.

6‑2. Power OFF

Press the「ON/OFF」key ①.

6‑3．Zero adjustment

Carry out the adjustment in surely normal measurement mode.

(Unit [μm] and [mm] are indicated non blinking.)

Press the probe against the substrate for adjustment (zero plate).

[Indication on the LCD ⑪changes as follows.]

↓←The buzzer emits a beeping sound.

Zero plate

Measured value [XX] is

indicated on the LCD ⑪.

Press the「ZERO」key ②.

(Both the probe contact to zero plate or not is possible.)

↓←The buzzer emits a beeping sound.

[CAL] is indicated on the upper left of the LCD ⑪.

[ 0 ] is indicated.

↓←The buzzer emits a beeping sound.

Press the probe against the zero plate several times, when closed values to [ 0 ] are indicated on the LCD ⑪,

the adjustment is acceptable.

When the indications are away from [ 0 ], repeat above procedures several times.

※When 「LLL」 is indicated while zero adjusting, its adjusting point is widely deviated

from a right position.

Repeat the zero adjustment 2 to 4 times after confirming no coating is applied to the

substrate and confirm zero is stably indicated.

【NOTICE】

Normal measurement mode : Units [μm] and [mm] are indicated non blinking on the right hand of the LCD ⑪.

Statistical measurement mode : Units [μm] and [mm] are indicated blinking on the right hand of the LCD ⑪.

Carry out the adjustment in surely normal measurement mode.

When the zero adjustment is carried out in the statistical measurement mode, [ 0 ] data while adjusting

is stored in the memory.

and press the probe against it.

Select a little thicker standard thickness plate than

a film thickness to be measured. Standard

Match the indicated value on the LCD ⑪to the thickness of the standard thickness plate

by pressing the「∧」・「∨」key ④.

(This operation is possible for both the probe is contacting to the standard thickness plate or not.)

↓←When the「∧」･「∨」key ④is pressed, [CAL]

is indicated on the upper left of the LCD ⑪with a

beeping sound of the buzzer and indication

[ＹＹＹ] of left figure changes.

The Indicated values traverse quickly by keeping on

the「∧」･「∨」key ④pressing.

↓

←When the indication match to the thickness of the

standard thickness plate, stop the operation of

the「∧」・「∨」key ④.

↓

The Meter is ready for measurement.

Press the probe against the standard thickness plate placed on the zero plate several times.

When the indication on the LCD ⑪is the same thickness or near with the standard thickness plate,

the calibration is acceptable.

When the indication deviates from the thickness of the standard thickness plate, repeat above

procedures several times.

【NOTICE 】

●Waitfor10to15minutes ※after power ON for the adjustment or calibration to raise the accuracy.

※Power is cut off in about 5 minutes by the working of the auto power OFF function.

In this case, turn ON the power key ①again and fully warm up the Meter.

●Carry out the「zero adjustment」and the「standard calibration」to confirm the accuracy,

even if on the way of the measurement.

●Applicable range of the standard calibration(CAL) is 10 μmto8.00mm.

When it is out of the applicable range, [ LLL ] or [ HHH ] is indicated.

When the indication is in locked condition, operate the Meter according to the next item

「6-5. Resetting the working curve ｣.

●When the new values are set for both zero adjustment and standard calibration , the last characteristic

of substrate (working curve) is erased and new set value (working curve) is memorized.

●If the calibration is carried out with the standard thickness plate in the statistical measurement mode,

the data of the standard thickness plate while calibrating are stored in the memory.

The stored 1 data is automatically erased by pressing the「∧」or「∨」key ④.

But, when the「∧」or「∨」key ④is not pressed, the measured data is stored in the memory.

Carry out the calibration in surely normal measurement mode.
