n. Use the keypad to set the fine scale to 75 mV (press 75, SHIFT, m, then

ENTER).

o. CONFIRM that the TRIG’D LED stays lighted and that the waveform

on screen is stable. That is, it does not move horizontally or vertically.

Also, CONFIRM that the waveform on the screen has one positive pulse

and a number of negative pulses. See Figure 1–30.
