In case the amplitude is small, loosen the two screws (#541)

that attach the GMR unit, and adjust the mounting angle of

the GMR unit.

, check the

MR head. If it is deformed, make a bending correction

for the MR head. If the correction is impossible or there

is no deform, replace the GMR 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.

Standard:

Amplitude of all pulses/wave-

forms is 80mV or more.

Note:

Check the waveform by moving the
focus ring back and forth from the

infinity-end to the close-end positions

entirely.

　③

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

�ow 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.
