P2-Mfu Motorized Focus Unit - Nikon SMZ25 Instruction Manual

 Torque of the focus knobs
The torque of the coarse control knobs can be changed by
turning the torque adjustment ring on the base of the left
coarse focus knob using a hex driver (nominal designation, 2:
supplied with the focus unit). When the torque is too low, the
vertical position of the zooming body may slide due to various
loads (such as its own weight or the load of the
counterbalance spring inside the focus unit). Be sure to adjust
the torque to an appropriate level. Note that turning the fine
control knob will cause the coarse control knob to also turn,
changing the torque of the fine control knob.
Tool storage space
The focus unit has a storage space for storing three tools on its rear side. A hex driver and wrench supplied with the focus
unit and the Intelligent nosepiece can be stored here.

P2-MFU Motorized Focus Unit

2.2
The P2-MFU Motorized Focus Unit consists of a square-type
support and a focus mount with the motorized focusing system.
The focus mount is attached with the SMZ18 or SMZ25 Zooming
Body through the P2-RNI2 Intelligent Nosepiece or the P2-FM
Focus Mount Adapter. The square support is attached with the
P2-PB Plain Base, P2-DBL LED Diascopic Illumination Base or
the P2-DBF Fiber Diascopic Illumination Base. Three types of
motorized stands can be configured.
Focusing movement of the motorized focus unit is conducted
using the focus knobs on the remote controller or the foot switch
connected to the remote controller. The vertical position (Z
coordinate value) is shown on the LCD on the remote controller.
Z coordinate value
The accuracy of the Z coordinate value (vertical position)
shown on the remote controller is not guaranteed. This
value is used as a reference and includes a margin error.
 Initialization at power on
When the microscope system has been assembled and the power of the control box is turned on, the motorized focus
unit is initialized as follows:
1 The power is turned on.
2 The focus mount moves upward to the upper limit.
3 The focus mount moves downward to the position before the power was turned on.
