EEROM Checksum Errors (700 to 704)
Faults on the A2 controller assembly can cause these errors. Refer
to Chapter 10, “Controller Section.” Although some of these errors
might result in a blanked display, it is possible to read these errors
over HP-IB. Refer to “Troubleshooting to a Functional Section” in this
chapter.
The EEROM on A2 is used to store data for frequency response
correction, elapsed time, focus, and intensity levels. Error codes from
700 to 703 indicate that some part of the data in EEROM is invalid.
An EEROM error could result from either a defective EEROM or an
