・

How to inspect and adjust:

①

Conrm that the electric current and voltage of the connected rated voltage power-supply are set values, then

turn it ON.

②

Set the oscilloscope. While holding the white gear of the SWM unit with tweezers, etc, up towards the

bayonet side, turn the focus ring manually.

Note: The waveform varies according to the rotational speed of the focus ring. So change "Time/Div” setting

accordingly.

　③

In case large waveform-noise (as shown in Fig. 1) is detected, use the FILTER function.

How to set FILTER function (e.g. DL1540 manufactured by YOKOGAWA

）

1. Press the FILTER button.

2. Select “Smooth” of the menu on screen and turn it ON.

Amplitude

In case the amplitude is small, disassemble up to the

stage of the zoom ring. Then if the deformation is
detected in the MR head, correct the deform of the
MR head. On the other hand, if such correction is
impossible or no deformation is detected, replace the
MR unit. (Fig.2)

Note: When adjustments are made, prevent the

magnetic surface and MR head from touching the
magnetized driver bit. Otherwise, the magnetic
data may be damaged.

● As shown in Fig. 1,

if the amplitude of only either CH1 or CH2 is small, one of the 2 screws (#218) may be

loosened, so check for it. If this is not the case, the MR head may malfunction, so replace the MR holder

unit and make a readjustment.

　●

As shown in Fig. 2,

if the amplitude partially drops between the innity and the close-distance, the

magnetic data of the tape may be damaged. So replace the main xed tube unit and make a readjustment.

Replacing only the magnetic surface is impossible.

Adjustment of MR duty

●In case of replacing the main PCB, SWM unit and MR encoder unit, be sure to make adjustments.

●In case of replacing the main PCB, be sure to perform [READING AND REWRITING OF EEPROM

DATA.] then [3.WRITING THE FIXED VALUES.]

　How to adjust

　① Make sure that the electric current and voltage of the connected rated voltage power supply are set to the

set values, which are instructed on the PC screen. Then, turn the rated voltage power supply ON.

　② Select "1. MR DUTY ADJUSTMENT" in the menu of the AF-S 18-55 inspection program.

　③ The conrmation screen for writing the xed values in EEPROM appears. Select the appropriate item.

　④ Following the instruction on the screen, rotate the MF ring slowly by hand in the direction from the innity

to the close distance position. Make sure that the waveform on the oscilloscope has duty 50% and stop the

MF ring at the close distance-end.

When the above Fig.1 is displayed, if the motor driving stops, select "Yes" to complete the adjustment.

In case the motor does not stop driving, select "No " to make adjustments again.

In case the motor does not stop driving even after the readjustments, adjust the MR duty again and repeat

"ADJUSTMENT FOR DRIVING FREQUENCY & MOTOR CONTROL".

If the adjustment is not successful in spite of the above, the SWM unit, x-tube unit, or MR head unit

may be defective.

Adjustment of Driving frequency and Motor control

● In case of replacing the main PCB, SWM unit and MR encoder unit, be sure to make adjustments.

　① The method of connection of the rated voltage power supply and measuring tools is the same as

"ADJUSTMENT OF MR DUTY".

　② Make sure that the electric current and voltage of the rated voltage power supply are set to the set values

on the PC screen.

　③ Turn the rated voltage power supply ON.

　④ Select "2. ADJUSTMENT FOR DRIVING FREQUENCY & MOTOR CONTROL" in the menu of the

Inspection of Lens operations

Check the lens operations by using a personal computer after assembling.

○ Check by personal computer

　● Check by the following considerations:

1.

MR encoder operations

　　・

Drive the scanning

of lens and check the total number of pulses.

　　・In case the MR head of the MR encoder and the magnetic tape are misaligned, the number of pulses

becomes out of standard.

2.

Lens-servo stop accuracy

　　・Check the number of overrun/underrun pulses (deviation of the stop position from the target position) per

the specied lens driving.

　　・In case the irregularity of mechanical operations does not take place in the focus ring driving unit, the

underrun tends to occur if it is heavy in the cam ring rotation of the MR encoder, while the overrun tends

to occur if it is light in its rotation of the MR encoder.

3.

Lens-servo time

　　・Check the servo time (from starting and stopping the servo) when driving the specied lens by using the

oscilloscope.

　　・In case the irregularity of mechanical operations does not take place in the focus ring driving unit, the

servo-time tends to be long if it is heavy in the cam ring rotation of the MR encoder, while the servo-time

tends to be short if it is light in its rotation of the MR encoder.

4.

Switches and lenses

　　・Check the ON/OFF operations of switches and the operating condition of the distance encoder.

　● After inspections

1. When the MR encoder operations are not up to the standard:

    Readjust the MR duty. (ref. Page A26.)

In case the pulse is not up to the standard, adjust the output waveform of the MR encoder again.
(ref. Page A5.)

    In case the pulse meets the standard, replace the cam ring unit.

2. When the lens-servo stop accuracy is not up to the standard:

    Check the output waveform of the MR encoder. If it is normal, replace the x-tube unit.

3. When the lens-servo time is not up to the standard:

    Readjust the driving frequency and motor control.

In case the lens-servo time is not up to the standard even after the readjustment, replace the x-tube

unit.

4. When switches do not work properly:

    Check the wiring state of the troubled switch or replace it.

1. Check the resolution

By shooting the high-denition resolution chart (J63079), conrm that the TV lines are within the standard.

Standard for the TV lines:
1400 or more TV lines in the center ; 1200 or more TV lines on the periphery /4 corners
at both WIDE (18mm) and TELE (55mm)

(ref. The unit of resolution is based on TV lines, which are total number of black-and-white strips
distinguishable on the TV screen.)

Device: D100 camera, ITE high resolution chart (J63079), icker-less uorescent (AAA)

(a) Camera settings: Shooting-mode: Aperture-Priority Auto (A), Aperture: Full, Image quality mode

(FINE), Image size (FULL), ISO (200), Image sharpening (None)

Reset other settings (e.g. compensation) and shoot pictures.

(b) To avoid light irregularity on the chart, for either 2 units of Z light (Z-309)(J19124) or 2 units of 15W

inverter-type uorescent stand, use uorescent lamp color-rendering AAA (J19124A). Set them so that
reected light does not directly come in shot images. (ref. Pic.1)

As for exposure, open the shot images via PHOTOSHOP, and make an exposure compensation so that

the value of RGV becomes 219±10 LSB, when the cursor comes to white parts of the images.

(ref. : Set the exposure compensation to about +1-step for becoming 219±10 LSB.)

To nd the best adjusted point, check the following: 90°→180°→270°. If all of these 3 points does not become

within standard, some defective parts caused by a damage such as shock should be considered. Therefore,

replace probable faulty parts (e.g. bayonet mount, 1st/2nd lens group, lter ring, xed tube unit, etc) and make

an inspection on resolution again.
