2.8V +/-0.1V
Black
Confirm the waveform of TP169(G) that ten
gradation has come out. And confirm that it is the
3rd gradation is 1.6V +/-0.2V.
Set the range of CH1 and CH2 of an oscilloscope to
1V.
Display CH1 and CH2 in GND. And match it to GND.
Display the waveform of TP169(G) on CH1 of an
oscilloscope.
Display the waveform of TP170(R) on CH2 of an
