Theory of Operation 7
1100 Series WS MWS Reference Manual 237
Stay-Resident Settings
Firmware update procedures may require this mode in case of firmware
loading errors.
Switches 1 and 2 do not force storage of this set of parameters in non-volatile
memory. Returning switches 1 and 2 to other positions (other than being both
up) will allow for normal operation.
If you use the following switch settings and power the instrument up again,
the instrument firmware stays in the resident part, that is, it is not operable as
a detector. It only uses basic functions of the operating system for example, for
communication.
To return to normal operation, set switches back to your GPIB or RS-232C
configuration settings.
