Infrared Sensor
After connecting the power supply, the metal detector starts to work. When there is
no person or object passes through the detector, the infrared sensors can
effectively stop alarming to avoid false alarms. It also helps to maintain an accurate
count of pedestrians and alarms.
6.1
Adjustment of Detection Zone’s Sensitivity
1.
The device must be in a stable position to achieve the best detection effect
(refer
Installation Site
). To check whether the device is in a stable state,
perform the following steps:
a)
Power on the detector and check whether it is not shaking after one
minute.
b)
The device should not alarm when the testing person did not carry any
metal items while walking through the detector.
2.
You can exclude the small portable metal objects such as rings, key, belt
buckle, shoes, and so on, by following the steps given below:
a)
Choose a small metal as a sample. Increase the sensitivity, so that when
the testing person carries the sample and pass through the detector, and
it would alarm.
b)
Decrease the sensitivity a little, carry the sample, and pass through the
detector again. If it still alarms, once again reduce the sensitivity, 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 relative zone. After implementing the above adjustments, the
metal which smaller than the sample will not alarm, but the metal objects bigger
than the sample can be detected accurately.
