Interlock control linked to the microscopy method
CAUTION
The interlock control is a function to change the electrically-driven devices of the microscope to the
pre-determined condition referring to the microscopy method and the objective when the
microscopy method or the objective is changed.
When the interlock control is enabled with "LVSetup," the illumination on/off status and the
opening of the aperture diaphragm for the episcopic illumination are changed in connection with the
objective and the microscopy method. The light quantity and the aperture diaphragm opening
changes differently depending on the interlock control setting, "Default mode" or "Optional mode,"
as described below.
• Default mode
The light quantity is set to the predetermined value. The aperture diaphragm for the epi-
illumination is automatically adjusted to 75% of the numerical aperture of the objective.
• Optional mode
The light quantity and the aperture diaphragm for the epi-illumination are set to form a diameter
and a value that has been set with "LVSetup."
Use "LVSetup" of "LV Series Support Tools" to set the interlock control. For detail information,
see "LV Series Support Tools software manual."
Modification from the registered condition (User offset)
When the light quantity or the aperture diaphragm for the episcopic illumination is modified from
the registered condition, the EPI switch or the DIA switch indicator starts blinking, indicating that it
is not in the registered condition. This modification is referred to as "User offset" hereafter.
The condition of "User offset" is registered in the microscope memory: therefore, the post-modified
condition is restored when the registered combination of the microscopy and the objective is
selected, even after another microscopy or objective is selected or the power is turned off.
CAUTION
To clear "User offset"
To clear the "User offset" condition and return to the registered
conditions of the illumination and the aperture diaphragm for the
episcopic illumination, hold down the EPI switch and the DIA
switch for two seconds or longer. When the registered conditions
are restored, a short beep sounds and the switch indicator turns
on.

To perform the interlock function properly, you must register the microscope
configuration and the objective information correctly.
Even if the interlock control mode is changed, the user offset settings are kept.
Therefore, if the interlock control mode is changed with "LVSetup" under conditions
of user offset, the microscope system condition may differ from user intension. To
change the interlock control mode, perform the following if necessary and reset the
user offset settings beforehand. For information to change the interlock control mode,
refer to the "LV Series Support Tools software manual."
