※BEFORE DISASSEMBLING, DISASSEMBLING AND ADJUSTING
①This lens loads the VR (Vibration Reduction) unit to perform the vibration reduction function.
To maintain the accuracy of the vibration reduction function, be sure to perform the VR adjustment by using the
VR lens adjustment equipment (J15380) when removing the VR unit and Gyro PCB.
However, the VR adjustment is not necessary when disassembling the other parts.
②The optical axis between the 1st lens group and the VR unit has been adjusted so that the optical axis would not
dislocate when the 1st group lens injects at zooming operation.
When replacing the 1st lens group or removing the VR unit, it is necessary to adjust the optical axis by using
the auto collimator and the special tool.
At the service facilities where [VR lens adjustment equipment] and [ Auto Collimator and Special Tool] are not
set up, do not repair or disassemble the product applicable to the above.

・How to conduct inspection and adjustment
Make sure that the current and voltage of the connected rated voltage power supply are set values.
①
If they meet the set values, turn on the power.
② Set the oscilloscope and drive the focus ring by hand.
Note：Since the shape of waveform varies according to the driving speed of B61, particularly and properly set
Time/Div.
In case of detecting any wider waveform noise, use the lter function.
③
How to set the ler function in the employment case of Yokogawa-manufactured DL1540
１．Press the lter button.
２．Select "Smooth" in the menu on the PC screen.
Standard：The amplitude of every pulse/waveform should be 50mV or more.
Note：Check the waveform by letting the B61 to travel from the innity-end position to the near distance end position
and vice versa.

《Reference》
● In case the amplitude of either CH1 or CH2 seems smaller, one of the two screws #96 may be loosened.
Then, check the screws. In case the screws are fully tightened, the MR head may be troubled. Then, be sure to
replace the MR head unit B88 and adjust it again.
In case there is a drop partially in the amplitude of vibration between the innity and the closest, replace the magnetic

tape (attached to B61) and readjust it because the data on magnetic tape may be damaged.
