2. Divide the input voltage selector setting (1, 10, or

100) by 4 (the number of vertical squares).

The result is the screen’s

vertical deflection factor.

For example, if the input voltage selector is set to

10, and you divide 10 by 4, then the screen’s ver-

tical deflection factor is 2.5 volts/square

Therefore, if a measured signal is about 3

squares high, then the signal is estimated to be

about 7.5 volts (3 ¥ 2.5 = 7.5).

Notes:

• The screen’s deflection factor applies only to the

oscilloscope screen on the computer’s monitor,

and does not apply to the display on the Probe-

Scope.

• The grid overlay is not necessary if you want only

to detect a signal but do not need to calculate

voltage or frequency.

• The grid is necessary in order to calculate volt-

age, frequency, or both without using the cursors.
