Step 6. Measure the DC voltages of the control lines using a voltmeter with a small probe. If
is set for each control line, the voltage of the control line is the same value as the output
voltage of the pin 12. If
same value as the output voltage of the pin 15.
• If any of the voltages of the control lines are not the same voltages as the pin 12 or pin
15, the A3 board is suspect.
• If all the voltages of the control lines are good, the A3 board is verified.
