Selftest (Maintenance) 
The Maintenance popup menu, which is accessible via the BASE function group in the Menu Select 
menu, complements the Info menu (see p. 4.18 above) in providing service information, selftests and 
correction procedures that are aimed to improve particular measurements. The selftests are primarily 
intended for production and service purposes and therefore not needed during normal operation of the 
instrument. The following description serves as a general overview.

The  Select  softkey selects the type of selftest or correction procedure to be 
performed.  
Note:  The Select drop-down list always contains all entries listed below. If 
the selftest is started for a board that is not available in the unit, a 
message “<Board_Name> board is not available” is displayed.  
System Info  Provides information on the system memory and the 
hardware and software configuration. If System Info is 
selected and the Test activated (see below), the CMU lists 
all deliverable hardware and software options in the report 
table and indicates whether they are available on your 
CMU.  
System Identity  Scans all modules and stores the part numbers and 
production data to file c:\identity.dat. In addition the 
available software versions are written to the log file 
C:\INTERNAL\LOG\VERSION.LOG.
