】
1. Install the Walk Through Metal Detector in a stable state could achieve the
best detection results (Please refer to "Installation Environment") Below are
steps for telling if the Walk Through Metal Detector is in a steady state:
1) 1 minute after start up, the Walk Through Metal Detector gate is under unshaking
state.
2) During test, there should be no alarm sound when tester passing the Walk Through
Metal Detector and not carrying any metal items.
3) Combined with the above two situation that the Walk Through Metal Detector is in
a stable state.

the walk through metal detector, and there will be alarming.
3) Appropriately lower the sensitivity, then take the sample & pass by the walk
through metal detector once again , if there is still an alarm sound, then continue
lowering the sensitivity until there is no alarm sound .
Notes:
if there is a certain detection zone needs lower the sensitivity, then only need to adjust
the relevant detection zone. With the above adjustments,for any metal objects that is
less than the sample will not alarm, and for the metal objects that are larger than the
sample all will be accurately detected.
3. Passing Rules.
1) Draw a waiting line of 50cm away from the front or back of the walk through metal
detector, so that the people being detected are queued to pass one by one
