6. Set Vertical Coupling to DC. If waveform appears
above reference line, voltage is positive. If waveform appears
below reference line, voltage is negative.
7. Measure vertical difference (in divisions) between re
ference line and desired point on waveform and multiply by
the VOLTS/DIV setting (CAL-Variable-must be in detent
setting).
