Vertical Control Area:
: Input channels. These two channels are
marked with different colors to distinguish different input channels
and their waveforms. Pressing the channel button will turn on the
corresponding channel as well as its menu, and pressing it twice
continuously will turn off the channel.
: Press the button to enable math function which includes
five operations: adding, subtracting, multiplying, dividing and FFT.
: Press the button to enable the reference waveform
function. By recalling the previously saved waveform, we could
compare it with the current waveform to decide circuit failures.
: Modify vertical position of the current waveform. Turn
clockwise to increase the position while turn counterclockwise to
decrease it. The waveform will move up or down and the position
message at the lower-left corner of the screen will change along.
Press down the knob to quickly reset the vertical position to zero.
: Modify vertical scale of the current channel. Turn
clockwise to decrease the voltage scale while turn
counterclockwise to increase it. The amplitude of the waveform will
