※ Before Disassembly / (Re)assembly / Adjustment
If the 1st lens group and 4th lens group of this lens are removed, lens alignment
becomes necessary after assmbling.
Therefore, at service agencies where the lens alignment cannot be performed,
remove neither the 1st lens group nor 4th lens group.

INSPECTION AND ADJUSTMENT FOR THE WAVEFORM OUTPUT FROM MR ENCODER
● In case of disassembling or replacing the MR head, be sure to make an adjustment.
1. Equipment and tools required
・Single output rated voltage power supply: 1 unit With 5.0V and 100mA, applicable to the self-
made tool
・Oscilloscope: 1 unit
・
Note:
Self-made tool: 1 unit
In case of any trouble in continuity between the self-made tool and the contacts of relay
FPC, there may be dust, corrosion or oxidation on the contact surface of relay FPC. Be
sure to polish the contact surface before getting connected to the self-made tool
.
2. Preparation for measuring lens
・Connect the xed tube, on which the MR head and magnetic tape unit were attached, to the
measuring devices. (Refer to the next page.)

・How to make an inspection and adjustment
Make sure that the current and voltage of the connected rated voltage power supply are set values.
①
Then, turn the power on.
② Set the oscilloscope and turn the magnetic tape unit by hand.
Note：Because the shape of waveform varies according to the driving speed of magnetic tape unit, set
Time/Div accordingly.
In case of detecting any wide waveform noise, use the lter function.
③
How to set the ler function by Yokogawa-manufactured DL1540
1.
Press the lter button.
2.
Select "Smooth" in the menu on the PC screen.

to move the MR head for adjustments as shown in Fig.1.
Note: During adjustment, prevent the magnetic tape and
MRhead from touching the magnetized driver bit.
Otherwise, the magnetic data may be damaged.

● In case the amplitude of either CH1 or CH2 is smaller, one of 2 screws (#123) may be loosened,
so check for it. But if this is not the case, the MR head is regarded as malfunctioning. Be sure to
replace the MR head unit and adjust it again.
