13MultiFinder ProManual calibrationPressing the CAL button (5) manually calibratesthe device. This allows measurements tobe restarted and objects to be isolated moreprecisely.Maximum sensitivity is achieved when the device is held inthe air while calibrating. This can be useful for METAL andAC-SCAN measurements.Briefly press the Mode button (4).METAL-SCAN: Detecting metal in allnon-metallic materialsAC-SCAN: Locating live lines directlyunder non-metallic claddingSTUD-SCAN: Detecting wooden wall beams and joists as wellas metal in drywall structures under non-metallic cladding5 Select measurement modeThe device and the wall must maintain contact duringcalibration in STUD-SCAN mode and throughout theentire measurement process. A hand should remain atthe device the entire time as well.!EN4 CalibrationAuto-CalibrationThe automatic calibration is performed in METAL-SCANand AC-SCAN measurement immediately when the deviceis switched on and when the measuring mode is switched.Auto-Cal PlusWhen an object has been found, the device performs anotherautomatic calibration in METAL-SCAN measurement. Thissimplifies the process of isolating objects to be measuredand adjusting the device to different surfaces.METAL-SCAN and AC-SCAN modeRed: metal or live wire foundSTUD-SCAN modeGreen: object found
