ALARM LEVEL (CONT’D)
Sample routine:
Press ACCESS until
ALARM LEVEL: #
(current alarm level setting) appears on the
LCD.
1. Note the alarm level that appears (e.g.,
ALARM LEVEL: 123
)
2. Press the + (plus) touchpad.
3. Ensure that you are metal free.
4. Hold the OTP or place it on your person.
5. Walk through the metal detector.
6. Note the new alarm level reading.
7. Change the test piece’s location and/or orientation.
8. Repeat steps two through seven several times until you are satisfied that you’ve per-
formed enough tests (i.e., an alarm sounds each time you pass the OTP through the
metal detector).
9. Choose the highest reading that detected the forbidden object.
10. Return to the base sense mode and enter the alarm level reading that you chose in
Step 8 as the base sensitivity. To confirm that the new base sensitivity setting is appro-
priate, test the OTP at varying locations and orientations within the walk-through, partic-
ularly in spots where you suspect detection is most difficult.
After choosing the base sensitivity, press ACCESS to make another adjustment or
OPERATE to resume normal operation.

SUPERVISOR RESPONSIBILITIES
7.1.
CALIBRATION
To maximize screening throughput, you need to properly calibrate the PD 6500. You
accomplish this by selecting the most appropriate program and sensitivity settings for
your security application.
Choose a program that easily detects all forbidden metallic objects, yet ignores innocu-
ous metallic items, such as jewelry, coins, belt buckles, etc. (For helpful tips on select-
ing programs, see Section 11.2.)
Next, select the lowest base sensitivity level at which the smallest forbidden metallic
object can be detected. (For helpful tips on selecting base sensitivity, see Section 6.2.)
Adjust the zone sensitivity settings as needed. (See Section 5.5.1.)
