Keithley 2016 - Power-Up Sequence

Power-up sequence
On power-up, the Model 2016 performs self-tests on its EPROM and RAM and momentarily
lights all segments and annunciators. If a failure is detected, the instrument momentarily 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 example
of this display is:
REV: A01 A02
where: A01 is the main board ROM revision.
A02 is the display board ROM revision.
NOTE The unit will display USER SETUP during power-up if a user setup has been saved.
After the power-up sequence, the instrument begins its normal display of readings.
