7. Diagnostics
7.1 Overview
If a system failure occurs, it is necessary to diagnose the cause before beginning the repair.
This section describes the diagnostic tools and techniques used to isolate various types of
system failures. This chapter covers the most common failures and their fixes. If the user is
unsure how to proceed with troubleshooting, please contact Technical Support.
The cause of some failures may be obvious. In these cases, the Service Engineer may proceed
directly to the repair. Before beginning an investigation, it is a good practice to record
as much information about the current state of the system as possible. This information
may include, but is not limited to, symptoms, conditions under which symptoms exist,
voltages, settings, cleanliness, and visual state. Normal generic troubleshooting techniques
apply. With knowledge of the system, isolate the failure to a particular subsystem. With
knowledge of the subsystem, trace the symptom back to its cause. In many cases, failures
are caused by lack of periodic maintenance and cleaning. If a system is known to be behind
schedule for its maintenance and cleaning at the time of the failure, it is a good practice
to clean and re-calibrate the system before extensive troubleshooting. In many cases this
solves the problem or provides clues as to the cause.
WARNING
This equipment is operated with hazardous voltages which can shock, burn,
or cause death.
CAUTION
This equipment uses a laser. Direct exposure to the laser beam must be
avoided.
CAUTION
Do
not
operate the unit with the covers removed. Operating the
i
CR 3600
with the covers removed may result in damage to
i
CR 3600and/or cause harm to the
operator.
Preliminary Checks
1.
Make sure the
i
CR 3600 is powered by at least a 1300VA (780W) UPS (uninteruptable
power supply).
2.
Make sure that the
i
CR 3600 is connected to the acquisition computer using a USB 2.0
cable (USB 1.0 or 1.1 cabling is not sufficient).
3.
Check that the
i
CR 3600 is powered by the provided power cable or source as covered
in Section 2.1.
4.
Make sure that other devices that emit strong radio frequencies are not in close
proximity to the iCR 3600.
