Operator Manual 342-9000-1 Rev. B ECCN EAR99
The following is a list of tasks that should be performed before operating the system. On a daily basis,
before turning on the system, make sure:
•
The Ethernet interconnection data cable, if used, is seated tightly into plugs and insulation is in
good condition.
•
Scanner battery and tablet are fully charged.
•
The scanner housing is clean and sealed, with no indication or signs of misuse or abuse.
•
The users are properly trained in the use of the system.
The scanner system immediately performs a self-diagnostic test, and several additional safety inter-
locks must be verified automatically before the system is enabled to emit X-rays.
•
Check status indicator LEDs (
Table 4-2
) for results of BIT tests.
In addition to checks before the system is turned on, the user should evaluate the performance of the
system as it powers-on:
•
Unusual noise or vibration in the motor assembly could indicate that consulting with AS&E Field
Service is appropriate.

Pre-Operation Scan Path Planning
The MINI Z™ system is designed for close-quarters maneuvering near objects being scanned, particu-
larly in confined spaces or zones where stationary X-ray systems cannot be used. However the MINI Z
produces an open X-ray beam, and careful preparation must be made to ensure the directed beam of
the MINI Z emission is never swung toward people or other living creatures, such as when going
around corners or rounded objects, or by penetration through the objects being scanned.
Before beginning each scan, review the scan path:
1. Ensure that:
•
a determination has been made and completed for the best handling of the tablet and scanner
unit,
•
a determination has been made and implemented with regard to operation by either one or two
users, and
•
a scan path exists that can be safely executed.
2. Position the scanner:
•
with the face (emitter front) end toward the object to be scanned,
•
at the top end of the scan path (left end for horizontal scans),
WARNING
When using the Ethernet cables to interconnect the scanner unit with the tablet or
the external detectors, be careful to provide strain relief at the connections, and to
avoid stepping on or tripping over cables.
