3. After removing all cables, press
F2
(Auto calibration) again. The Auto-calibration automatically
starts and a message appears, showing that the calibration is ongoing.
To interrupt calibration, press any key during the calibration.
8.9 Making Automatic Measurements
The oscilloscope can perform 18 types automatic measurements such as frequency, cycle, average
value, peak-to-peak value , root mean square value, Vmax, Vmin, Vtop, Vbase, Vamp, Overshoot,
Preshoot, Rise Time, Fall Time, +Width, -Width, +Duty, -Duty; and gives two kinds of
measurement results simultaneously on the screen.
The function menu for automatic measurements is described in the following list.

To measure the frequency of waveform with
Measurement 1
and the peak-to-peak value of
waveform with
Measurement 2
, do the following:
1.
Press the
MENU
key and the function menu is shown at the right of the screen.
2.
Press the
MENU
