BASE SENSE (CONT’D)
Sample routine:
Press ACCESS until
BASE SENSE: #
(current base sensitivity setting) appears on the
LCD.
1. Note the base sensitivity setting that appears (e.g.,
BASE SENSE: 165
)
2. Ensure that you are metal free.
3. Hold the OTP or place it on your person.
4. Walk through the metal detector.
5. If an alarm sounds, go to Step 7.
6. If no alarm sounds, increment the base sense number by five (e.g., from 165 to 170)
and reenter the walk-through. Repeat this process until an alarm sounds. Note the new
base sense number. (Note: to fine-tune the setting you may want to increase or
decrease the number by one.)
7. The response of a detection field depends on the location AND orientation of the for-
bidden object. Therefore, repeat the aforementioned routine at least five times; each
time changing the test piece’s location and/or orientation and noting each base sensi-
tivity setting that triggers an alarm.
8. Once you are satisfied that you have performed enough tests, (i.e., an alarm sounds
each time you pass the OTP through the metal detector) choose the lowest setting that
detected the forbidden object AND overlooked most innocuous items.
Special Note:
When performing tests, you should place the OTP in locations/orientations where you
suspect detection would be most difficult.
After choosing the base sensitivity, press ACCESS to make another adjustment or
OPERATE to resume normal operation.
6.3. IR ANALYSIS
(
IR ANALYSIS ON
)
An infrared sensor improves the analysis of the detection signal, increases traffic flow,
helps prevent false alarms and provides an accurate traffic count. Although useful, the
IR Analysis is not required for operation and may be disabled if desired using the minus
(
–
) touchpad.
Press
ACCESS
for the next adjustment or
OPERATE
to resume normal operation.
6.4.
ALARM LEVEL
(
ALARM LEVEL 123
)
Alarm level is an optional tool that helps you determine the lowest level of sensitivity
required to activate an alarm for a particular metal object. This information can then be
used to determine the desired level of sensitivity.
