❍ When dome is removed unscrew the knurled head screws at the analyzer module‘s sides
(fig. 15-12) and pull it to the front until the last screw locks into the detent (fig. 15-13).
Note!
Mark or remember the detent where the first knurled head screw was placed, to place it there
again when assembling the unit!
Otherwise it may happen the analyzer is not magnetically operable any more because the
distance between front panel and glass it to great.
