10. Measurement mode Magnetis mode: It is for measurement of coating thickness Single measurement:The probe touches perpendicularly and of magnetic substrate and cannot be used to measure the presses against the tested objects slightly. After completion coating thickness of non magnetic conductive substrate. of test, lift the probe and carry out measurement of the next Vortex mode: It is for measurement of coating thickness of time.
13. Calibration Method A i r There are two types of calibration methods. We recommend using calibration method Ⅰ for calibration. The instrument is calibrated properly before delivery. Users may carry out recalibration if it is necessary. Calibration Method-1 Figure 1 Preparation before calibration: 3.
