( E d d y C u r r e n t m e a s u r e m e n t m e t h o d : Fo r measuring the thickness of insulating coatings on non-magnetic metal substrates)

Aneddycurrent isproduced in thesurfaceofametalwhenacoil throughwhichacurrentof fixed frequencyis brought near the metal. This eddy current and the voltage at the ends of the coil change in proportion to the distance between the coil and the metal surface. This change can be determined from the current value and thisisusedtocalculatethethicknessofthecoating.

•LE-373

(Electromagnetic measurement method : For measuring the thickness of non-magnetic coatings on magnetic metal substrates)

When an alternating current electromagnet is brought near iron (or other magnetic metal) the number of magnetic flux lines passing through the coil changes in proportion to the distance, thereby causing a changein the voltage at the ends of the coil. This change in voltage is determined from the current value and this is usedtocomputethethicknessofthecoating.

* In the case of “Continues”, the measurement value to be displayed is read once it has stabilized after the tip of the probe has been applied to the measurement surface. Therefore, this measurement method allows the obtainment of a relatively stable measurement value when measuring a piece of irregular shape that tends to yield unstable measurement values and Statistics is conducted easier. If the printer is connected, the measurement value can be printed.

(1) I f the screen on the r ight is displayed, selectEscby pressing the →key,andthenpress theEnter key to returnto the measurement screen.

* In the continues measurement mode, press the enter key when the measurement value has stabilized while placing the probe tip on the measurement surface. The value displayed at that time is recorded as measurement data.

* Note that the measurement method for calibration differs betweenthe“Hold”andthe“Continues”(seep.30).
