The CKX31/CKX41 is a culture microscope newly adopting the UIS optical system and is
CKX31/CKX41
placed as the successor to conventional CK30/CK40. In electrical unit, the circuit board
3) Since the optical axis adjustment for binocular tube of CKX31 is basically the same as that
of CK30, the adjustment procedure is not written in this manual. Therefore, it is referred to
CK30/CK40 repair manual.
4) The above matter is also applied to CKX41. Therefore, this manual instructs the reference
page in CH3-BI45 repair manual when U-CBI30-2 is repaired.
In case where the other observation tube, which can be combined with CKX41 frame, is
repaired, refer to each corresponding repair manual.
is used, which corresponds to world-wide voltage by built-in voltage changeover switch.
This manual has been written on the premise that the service engineer already has experience
thoroughly the procedures of optical axis adjustment in CK30/40 and CH3-BI45 repair
manuals because the explanation of these parts are ommited as a common repair skill.
In optical adjustment section, parfocality adjustmet is mainly explained on D-6 and D-12.
The parfocality is required to adjust precisely due to severe standard compare with CK30/40.
2) Before optical adjustment, refer to jigs used in CKX31/ CKX41on D-4, D-9 and D-10.
5) Since the descriptions of disassembling and assembling procedures are simplified,
start disassembling according to the order of steps from (A) and assemble in reversed order
while taking care to follow the applied locations of grease/adhesive and remarks.
(The applied locations of grease/adhesive and adjustment part on components of assembly
are shown in exploded diagram.)
The “remark” column provides important notes and supplemental information.
6) Voltage adjustments will be needed when replacing the rheostat ass’y (DZ308500) or
circuit board (DZ308400) respectively. These adjustments can be made by following the
instructions given in this manual.
1) For overview of optical adjustment, refer to D-1 and D-2 in the section of repair procedure.
