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.

In case the amplitude is small, check if there is
deformation in the MR head. If there is, correct the
deform of the MR head. However, if such correction
is impossible or no deformation is detected, replace
the MR sensor 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. 3, if the amplitude of only either CH1 or CH2 is small, one of the 2 screws (#75) may be
loosened, so check for it. If this is not the case, the MR head may malfunction, so replace the MR sensor
unit and make a readjustment.
