Calibration of Metal Detection Machine
Calibration of Metal Detection Machine Conveyor detectors should be calibrated to 1.0-1.2 mm/customer’s standard ferrous object detection. The 9 Point calibration ensures that the equipment is functioning correctly and operating at the correct sensitivity (1.0, 1.2mm or as per customer’s standard). • The 9 Point calibration must be done a minimum of 2 times per shift or every time when the machine is out of power/switched off by a certified and trained operator. It is recommended to do it every hour. • Proper documentation of calibration should be maintained. Tools Required For Calibration Metal/ needle detector test card and stand The procedure of Metal Detection Calibration 1. The 9 Point Calibration check on the detector is done by dividing the metal detector conveyor belt into 3 zones. 2. The Calibration Card, supplied by machine vendor, should be passed through each of these zones at three different height levels. ...
