3. PRINCIPLE AND CONFIGURATION
3.1 Measurement principle
DJ-6B porosity detector provides certain impulse-voltage on the surface of protective coating or painting, where covered above the metal material basement. If the protective layer exists pinholes or the coating is too thin, the detector will release sparkle and give impulse signal to alarm component. The alarm component will beep and beep, and point out harmful points to the operator.
3.2 Holliday Detector DJ-6B Configuration
DJ-6B porosity detector is constituted of main unit, high voltage generator and probe brushes.
a. LCD display b. Voltage control c. On switch d. Earphone jack
e. Power indicator f. Low Power indicator g. Charging indicator
h. High voltage probe connector i. Backlight sensor window
