Focus Knobs On The Main Body - Nikon Eclipse Ni-E Instruction Manual

Enabling/disabling the operation of the elevating section
You can disable the operation of the elevating section.
As factory default setting, a focus knob is used to drive the elevating section, but you can "disable" the setting when an
application software such as NIS-E is used to control the elevating section or you wan to prevent unintended behavior
of the elevating section, including an accidental contact of the focus knob of Ni-E microscope or ergo controller (or
joystick). (See "20 Operation on DS-L3" - "20.1 Setting Up the Microscope - (6) Configuring Other Functions" for
details.)
Lower limit of the movement
The default lower limit of the elevating section is set to -2000.000 μm, but this can be changed with software. The lower
limit can be set between -2000.000 μm and -250.000 μm. (See "20 Operation on DS-L3" - "20.1 Setting Up the
Microscope - (6) Configuring Other Functions" for details.)
Changing the upper limit is not available.
Stop position by focus restriction
When operating the elevating section with the focus knob, the actual stop position is up to 20 μm beyond the set
upper/lower limit.
