Calculated values and deviation are updated continuously and the
deviation can be read (see Figure 144 below).

Figure 144 Linearity Test Menu, Filter Applied
The applied filter value is given. The calculated values are displayed as
269.8 m for MOR and 71.6732 % for transmittance. The deviation of the
current measurement compared to the calculation can be read by the
means of the values for Deviation (abs.) and (rel.) for MOR and
transmittance.
NOTE
Take into account that all measured values are 1-minute-averages. After
applying an optical filter, the system needs its response time to handle
the new situation.
NOTE
The 2-minutes-Variation-versus-current-Measurement is given only
when the latest action (entering the menu page, applying the filter,
removing the filter) occurred longer than two minutes ago. Otherwise it
is replaced by dashes ('---------').
The Reference-Quality-Indication is given only when, by procedure, no
filter is applied and the latest action (entering the menu page, removing
the filter) occurred longer than two minutes ago. Otherwise it is replaced
by dashes ('--------'). See Figure 145 on page 250.
If any other optical filter will be applied or the linearity test is finished,
the user has to remove the currently applied filter first.
Remove Filter After Measurement! Done? (yes/no):
