Features: This product has a built-in magnetic induction and vortex dual principle probe, can automatically identify the measured metal substrate, only need to be placed on the measured surface, can automatically calculate the thickness of the coating. Measuring step: Step 1. Prepare the parts to be checked. Step 2. Stay at least 2cm away from the metal object, press the shift button to turn on.Note: It is recommended to set the device to zero beforehand with reference to "zero calibration" test. Step 3. The probe is placed vertically and quickly on the surface to be measured until the dripping is audible and theReading is displayed on the screen, and then the probe is moved at least 2 cm away from the part to be measured.and the next measurement can be carried out.Note: If the automatic shutdown function is turned on and there is no operation within 3 minutes, the device will automatically shut down.
