(6) 2-point calibration in case it is difficult to perform 「Zeroing」

In case zeroing is difficult to perform such as measuring the thickness of the film on the rough surface of Blast-steel plates,
a calibration method using 『2 different thicknesses of standard plates』 pinching a thickness of the object is defined as
｢JIS K5600｣ Standard. This calibration method complies to the regulations.

Caution

It is not possible to use both this calibration method and other calibration ones together, or mixing them together.
Should were the methods taken, measuring results could be the wrong values.

Note to improve measuring accuracy

① Zero plate

Prepare the same material, thick and sized plate as the measuring object for Zeroing and Calibration
standard (CAL). Different materials may not bring about correct measuring results.
※As accessories to probe, “Zero plates for Zeroing” is for testing purpose only.

Select a most suitable Zero plate for actually measuring objects. (please refer to page 9)

② Thickness standard (foils)

Take Calibration standard measurements (CAL) using a Thickness standard which is thicker or as thick as
the measuring films.

※Use of a calibration standard with a deviant thickness may cause errors.

Replace worn-out or bent plates with new ones. In case non-accessorized plates are necessary
(over 16μm), contact a local sales office.

③ Quality of films to be measured

Magnetic metal contained in the films can correctly not be measured. In case of measuring elastic films,
place a standard plate of 30～50 μm thick on the object and subtract the thickness from the measuring
value to avoid errors caused by elastic dents.

④ Measurements of edges or angles

Magnetic fields in the neighborhood of the edges/the angles of a measuring object become uneven.
15～20 mm closer part to the center of the object shall generally be measured.
Pay attention to protruded part, curved part or unexpectedly deformed part.

⑤ Measurements of rough faces

Roughness of a substrate, a measuring face affects measuring results.
Take a mean value by measuring several places at a time.

⑥ Measurements of stretched part on faces

In some case stretched, rolled part occurred on a substrate, which may cause measuring errors.
Take a mean value by measuring several places at a time.

⑦ Temperature

Operating temperature range is 0～40 ℃. Especially, large temperature differences between a main unit
and a probe cause measuring errors.

⑧ Residual magnetism, stray magnetic fields

Pay attention to transportation method of electromagnets, residual magnetism on substrates or arc welding,
those of which emit strong magnetic fields to cause measuring errors.

Reference (Principle of measurements)

●

Electro-Magnetic Induction type (Electromagnetic Type)

When iron (ferrous metals) approaches to the tip of the coil built-in core, the inductance of the coils changes
in response to changes of the approaching distances. Electromagnetic Type coating thickness meters take
measurements of thicknesses of coating films by using this technical Principle and taking out the changes of

the distances in state of electric signals .

●

Eddy Current Type

By using correlations of the sizes of Eddy current induced on the metal surface by High frequency wave
magnetic field and film thicknesses, Eddy Current Type coating thickness meters take measurements of

thicknesses of insulating films on the surface of non-ferrous metals.
