pulses. This message may be due to stuck forcing lines not disabled during
troubleshooter setup procedures described in the Operator Manual.
• Any recurring UUT test-failure or error message when testing a known-
good UUT indicates pod failure. Since the UUT is known to be good,
errors attributed to the UUT by the troubleshooter are actually pod
errors.
Troubleshooting the pod is similiar to troubleshooting any other
microprocessor-based UUT, and requires the equipment listed in Table 5-2. The
troubleshooting information presented in the following paragraphs does not
provide step-by-step fault isolation procedures, but provides a troubleshooting
guide for use while employing normal fault isolation techniques.
Figure 5-1 shows the non-component side of the interface PCB with component
outlines and identification superimposed. Refer to this figure to locate various
electrical points on the interface PCB during troubleshooting procedures.
The troubleshooting information should be used in conjunction with the
schematic diagrams contained m Section 7 and the Theory of Operation
presented in Section 4.
The troubleshooting guidelines presented in the following paragraphs are
intended to assist in the isolation of faults within the pod. If attempted
troubleshooting fails to reveal the pod fault, return of the pod to the nearest
Fluke Service Center is recommended. Refer to the troubleshooter Service
Manual for a list of Fluke Service Centers.
