a)
Choose a small metal as a sample. Increase the sensitivity, so that the device alarms
when the testing person carries the sample and pass through the detector.
b)
You need to decrease the sensitivity a little and pass through the detector again
carrying the sample. If it still alarms, you need to reduce the sensitivity once again,
until the device does not alarm when the sample is passed through.
Note:
If you want to decrease the sensitivity in a certain zone, you must only adjust the
sensitivity of the related zone. After implementing the above adjustments, the metal smaller
than the sample will not generate an alarm, but the metal objects bigger than the sample can
be detected accurately.
