Instrument Settings"). In addition, all data and/or lists the user enters himself, such as for list mode,
memory sequence, and user correction of the level, are stored in the RAM. Further, all data of the
calibrations running within the instrument in the SMR are stored in the RAM (cf. Chapter 4, section
"Calibration" and Service Manual Instrument). A lithium battery with a service life of approx. 5 years
serves to supply the RAM with power. When the battery is discharged, the data stored will be lost.
Exchanging the battery is described in the Service Manual Instrument.

All parameters and circuit states, even those of operating modes which are not activated, are preset by
means of Preset. The presettings going beyond the above list can be seen from the menu
representations as of Chapter 4 which each indicate the Preset setting status.
Functional Test
On switching on the instrument and permanently during operation, the SMR carries out a self test. The
ROM contents as well as the battery of the non-volatile RAM are checked. The most important
instrument functions are automatically monitored during operation. If an error is detected, the message
"Err" is displayed in the status line. For further identification of the error, press the [ERROR] key.
Thereupon a description of the error is displayed (cf. Chapter 9, section "Error Messages"). Return to
the menu exited by pressing the [BACK] key. If required, internal test points can be polled by the user
and the results be read out and displayed. Cf. Service Manual Instrument.
Mounting into a 19" Rack
CAUTION
Ensure free air inlet at the perforation of the side walls and air outlet at the rear of the
instrument in rack mounting.
The SMR can be mounted into a 19" rack by means of rack adapter ZZA-94 (stock no. 396.4905.00).
The mounting instructions are attached to the adapter.
