The linearity test result is sufficient when the MOR deviation is less than
±10 %. The tolerable transmittance deviation varies for different MOR
simulations.

Figure 145 Linearity Test Menu, Reference Update
Service Menu
Due to the system topology, the transmitter/receiver measurement units
are connected to the module bus and are thus hidden for user access. For
the users' convenience, a subset of commands for the measurement unit
maintenance are available by the LT31 system maintenance port, namely
the
Service menu. Furthermore, an overview of measured raw values are
displayed. On the user command level, the subset of commands and the
display of values is restricted. Full access is given on the advanced
command level only.
Figure 146 and Figure 147 on page 251 show the Service menu on user
command level and advanced comm
and level, respectively.
