4. Clean an object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-Curve Check
Connection:
Procedure:
1. Connect the oscilloscope to TP (FE) and TP (VC) on BD board.
2. Connect the TP (FEI) and TP (VC) with lead wire.
3. Turned power switch on.

2. Connect the TP (FEI) and TP (VC) with lead wire.
3. Turned power switch on.
4. Put disc (YEDS-18) in and turned power switch on again and
actuate the focus search.
5. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak level
within 3.0 ± 1.0 Vp-p.

6. After check, remove the lead wire connected in step 2.
Note:
• Try to measure several times to make sure that the ratio of A : B
or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the brightness
to obtain best waveform.
