Good Example
VOLT/DIV : 100mV TIME/DIV : 1ms 100mV 0V

�

Incorrect Examples (Fundamental wave appears)
VOLT/DIV : 0.2V TIME/DIV : 2ms 0V

low tracking gain

�

Incorrent Examples (DC level changes more than on adjusted waveform)
VOLT/DIV : 100mV TIME/DIV : 2ms

VOLT/DIV : 0.2V TIME/DIV : 2ms

0V

200mV
high tracking gain (high fundamental wave than for low gain)

0V
low focus gain

[MAIN BOARD] (Conductor side)
VOLT/DIV : 100mV TIME/DIV : 2ms

75mV 0V

high focus gain

5. 6. 7.

Connect an oscilloscope between TP (TE) and TP (VC). Insert disc (YEDS-18) and press the CD ^ button. Check that the waveform is as shown in the figure below. (tracking waveform)
Oscilloscope (DC range)
VOLT/DIV : 0.2V TIME/DIV : 2ms

TP (TE)

TP (FE)

TP (VC)
0V
