Mirror Residue
The Mirror Residue Indicator graphically shows the amount of mirror contamination that was detected
during the last mirror check. If the bar covers more than a quarter of the space, we recommend that
you clean the mirror.
Optic Power
The optic power indicates the aging of the LED. When the instrument is used at higher measuring
head temperatures, the LED will age more quickly. When new, the optic condition bar graph will show
as ‘full’. When the indication starts to decrease, it provides the user with advanced notification that the
LED of the optical module may need service or replacement.
Fixed Function Keys

The menu selection is circular. Once you go past the last menu, the first one will appears again and
the process starts over. You can use the

The bottom line of the display
contains a row of fixed function
keys. These keys are used to
start and stop the gas flow fan

a mirror check, initiate mirror

information on the fan see

menu keys. The bottom, dark gray key changes the cur-
rent menu by cycling to the next menu. Each of the light
gray keys changes their label and function based on the
menu that is currently selected.
