Default permissions for operators are limited to logging in, selecting a test, and running a
test. The procedures in this chapter are based upon these defaults.
For detailed explanations of the Z1800-Series software, see the Z1800-Series
Programmer's Guidebook.
You must prepare yourself and your test system properly before you can perform
consistently successful board tests. The figure below shows the preparation and test
process.
These procedures are covered in detail in the two sections, “Daily Operations” and “Board
Testing.”
The section titled “Testing Digital Connectivity” describes a tool used for testing the
connectivity of digital components.

The “Troubleshooting for Operators” section covers occasionally occurring problems
which operators can easily remedy.
