Power-up sequence
On power-up, the Model 2000 performs self-tests on its EPROM and RAM and momen-
tarily lights all segments and annunciators. If a failure is detected, the instrument momen-
tarily displays an error message and the ERR annunciator turns on. (Error messages are
listed in Appendix B.)
NOTE If a problem develops while the instrument is under warranty, return it to Keithley
Instruments, Inc., for repair.
If the instrument passes the self-tests, the firmware revision levels are displayed. An ex-
ample of this display is:
REV: A01 A02
where: A01 is the main board ROM revision.
A02 is the display board ROM revision.
After the power-up sequence, the instrument begins its normal display of readings.
