The coarse focusing in the Z-axis direction is available with the FOCUS
buttons a . Holding a button continuously increases the movement
speed (up to 8 mm/sec.).
When moving the Z-axis, do not touch around the
focusing unit. Your hands or fingers may be pinched
between the focusing unit and the focusing unit opening
or the stopper.
CAUTION
} When rotating the coarse focusing knob b or the fine focusing
knob c for one turn, the movement distance in the Z direction can
be selected.
Movement distance adjustment
The movement distance of the coarse focusing knob b and the
fine focusing knob c are changed every time the F SENS button
d is pressed.
The movement distance can be confirmed by the indicator e of the
control box for motorized STM7-CBA or the FOCUS f of the digital
indicator STM7-DI.
