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
The thickness of non-conductive films treated on
non-magnetic metallic substrate can be measured non-
destructively, simply, speedily, and accurately utilizing
the electric correlation between the eddy current
induced on metal surface by a high frequency electric
field and the thickness of the surface film.
When a metal is moved toward or away from
a coil which carries electric current supplied
by a high frequency electric source, the current increases or decreases in accordance with a distance
from the coil.
This principle is utilized to measure the thickness (D) of non-conductive film on non-magnetic metallic
substrate.
２．APPLICATIONS
The Meter is used for non-destructive measurement of the thickness of a non-conductive film e.g. ALMITE,
paintings, linings, etc. applied to non-magnetic metallic substrate e.g. aluminum, aluminum alloy, copper, etc.
and austenitic stainless(non-magnetic stainless) steel substrate.
The Meter can be applicable for various domestic and foreign standards and rules.
●Anodic oxide films Measurement of the thickness of ALMITE(anodic oxide films)
applied to aluminum sashes, kitchen utenciles, electric appliances, etc.
●Paintings Measurement of the thickness of coatings applied to housing materials,
machines, tanks, etc. made of aluminum or stainless steel.
●Linings Measurement of the thickness of linings applied to machines, parts,
chemical plants, etc.
●Resin films Measurement of the thickness of films, papers, etc. based on aluminum plate.

８．REPLACING THE BATTERY
When the battery closes to the limit of use
due to consumption,「LOBAT」is indicated on
the lower left of the LCD ⑦.
As it causes malfunction under this condition,
replace the batteries earlier.
Replace the batteries after surely power OFF.
When the batteries are replaced under power ON, (Indication of battery's voltage drop)
it causes out of order of the Meter.
Replace all 4 batteries with fresh specified dry
batteries.
(Battery: Dry battery R03( 1.5V) × 4 pcs)
９．MAINTENANCE AND INSPECTION
●Use the Meter within the range of 0 to 40 ℃．
Avoid to expose the Meter to dew condensation, wet with water, dust, intense heat, vibration, etc. in use.
●Handle the probe cautiously not to damage on its tip.
●Keep the Meter in a dust-free place where high temperature and high humidity can be avoided.
●In case the Meter is left on no use for 1 month or more, take the batteries out of the Meter.
●To ensure accurate measurement, regular inspection of the Meter at least once a year is recommended.

10. CARES TO RAISE AN ACCURACY OF THE MEASUREMENT
①Zero plate
For use in the zero adjustment and standard calibration(CAL), prepare the zero plate which is
same kind, thickness and shape as the substrate of an object to be measured.
It will result in an inaccurate measurement to use the zero plate which is different
specifications from an object to be measured.
※Attached zero plate (For eddy current: Aluminum 1050) for test is for operation
test of the Meter.
Prepare the substrate of an object to be actually measured.
②Standard thickness plate
Carry out the standard calibration (CAL) with a little thicker standard thickness plate than a film
thickness of an object to be measured.
※It will cause an erroneous measurement to use a too thicker or too thinner
standard thickness plate than a film thickness of an object to be measured.
When the standard thickness plate has been damaged or bent, renew with a new plate.
In case the standard thickness plates other than the attached plates are necessary, please contact us.
(15μm th. or more)
③Characters of a film
The measurement of the film having a metal substance causes a measurement error.
With respect to an elastic film, place a standard thickness plate with 30 to 50 μmonitandsubtract
the thickness of the standard thickness plate from the total thickness, then the measurement error
due to film dent can be prevented.
④Effect of edge and corner
The edges, corners and their surroundings of an object to be measured are the places where the
condition of a magnetic flux is not uniform.
Generally, measure inside taking 15 to 20 mm or more away from the edges.
The same care is needed for a projection, bend, sharp deformed portion and surrounding.
⑤Effect of surface roughness
The surface roughness of both substrate and film of an object to be measured affects the measurement
results.
Take several spots to measure and calculate the mean value.
⑥Effect of rolling
In some cases, rolling strains exist in a substrate and it causes an incorrect measurement
depending on the spots to be measured.
Then take several spots to measure and calculate the mean value.
⑦Effect of the temperature
The range of the operating temperature is within 0 to 40 ℃.
Especially, when the temperature of the probe much differs from the Meter, it causes an erroneous
measurement.
