Perfect Focus System
Problem
Possible cause
Countermeasure
PFS information is not selected as a
display item.
Press the DISPLAY switch to display PFS
information.
PFS information not
displayed on status
display panel.
PFS Motorized Nosepiece not
connected.
Attach and connect the PFS Motorized
Nosepiece correctly.
The system is detecting the boundary
surface.
(This is normal behavior.)
The system continues to detect the
boundary surface even when PFS is
OFF. The FOCUS indicator will be lit
when the boundary surface is detected.
The indicator can be used to assist in
focusing.
FOCUS indicator lights
up while PFS-ON switch
is OFF.
Registered objective information
incorrect. (Registered information does
not match the objective in use, or
information for a PFS objective is
registered but no objective is attached.)
Register correct objective information.
If no objective is attached, delete the
objective information.
Offset already at limit of adjustable range.
Rotate dial in the opposite direction. The
offset function must be used within the
adjustable range.
Focus position cannot
be moved with the
offset dial.
PFS Offset Controller attached
incorrectly.
Turn off the power. Disconnect and
reconnect the PFS Offset Controller.
MEMORY switch pressed during offset
recall operation.
Retry after offset recall operation is
complete.
Offset cannot be
registered by pressing
the MEMORY switch.
(No beep)
Objective in the optical path does not
support PFS.
(Panel display: ER1)
Register the objectives correctly, and
move an appropriate objective into the
optical path.
Offset cannot be
restored by pressing
the RECALL switch.
(No beep)
Objective in the optical path does not
support PFS.
(Panel display: ER1)
Register the objectives correctly, and
move an appropriate objective into the
optical path.
Objective in the optical path does not
support PFS.
(Panel display: ER1)
Register the objectives correctly, and
move an appropriate objective into the
optical path.
PFS does not operate
when the PFS-ON
switch is pressed.
(Six short beeps)
Dichroic mirror in the PFS unit is not in
the optical path.
(Panel display: Out)
Move dichroic mirror into the optical path.
No specimen on stage.
Set a specimen and focus on it manually.
Objective too far from boundary surface
of specimen.
Rotate focus knobs to move objective
closer to the boundary surface.
“DIS” appears on the
status display panel.
Shape or material of specimen not
suitable for PFS.
Use a specimen suited for PFS.
PFS will not function if the cover glass is
too thick or if the refraction index of the
solution is too high (n is close to 1.5).
See “Supported Specimens” on page 82.
