Instructions!
• When measuring a signal whose frequency is unknown, user has to try to collect the waveform
from the fastest time base and then gradually select the slower time base until the signal can be
displayed correctly. Otherwise, due to "aliasing effect", waveform may fail to correctly reflect
the actual situation of the signal.
• There are several ways to avoid aliasing effect: adjust the time base or press "R" button.
Amplitude adjustment
Under the main option menu of oscilloscope mode, press F2 key (RANGE) to enter into the sub-option menu of
vertical control:

1. Press the F1 key (EXIT) to exit the amplitude adjustment sub-menu and return to the main menu.
2. Press the F2 key (X1X3). The F3 key (X10) is used to adjust the vertical amplitude (V/div).
Note: The F2 key (X1X3) switches back and forth between X1 and X3, and the F3 key (X10) cycles from small to
large.
