ENGLISH
Example: measurement of a 1.6V positive voltage; range 1V/div.
(1.6 div. x 1 V/div. = 1.6 V)
Example: measurement of a 20V negative voltage; range 10V/div.
(2 div. x 10 V/div. = 20 V)
4.1.2 A.C. Signal amplitude and period measurement
The signal to be measured is fed into either input YA (7) or YB (8).
Select the desired channel YA (15) or YB (16).
To measure the peak-to-peak voltage, it is not necessary to establish the 0-
Volt reference. Toggle the lever (13) on position ~; if necessary, centre the
trace in the screen by rotating the position knob (11).
The voltage value is obtained by multiplying the number of divisions
between 2 opposite peaks by the range used on selector (9).
