Time waveform
The measurement results are displayed as an XY diagram in the top
section of the window (see the standard setting). The data field in the
lower half lists the two highest amplitudes (positive & negative). If a
limit value is exceeded, the absolute value and the difference to the
measurement value is displayed ('delta', see below).
The following functions are available for evaluation of the result:
Zoom the time (X) axis
• Press on the rocker key '+' to magnify the X axis. Depending on the
zoom mode (page 4-16), the main cursor is used as the central
point or the gap between the main and delta cursor is magnified.
The '–' key is used to zoom out.
Scaling the amplitude (Y axis)
• Move the joystick upwards / downwards to change the scaling of
the Y axis.
Rotational speed marker
The yellow rotational speed markers indicate the trigger pulses
during signal measurement. In the circular plot, the speed markers
also indicate the direction of rotation (see the next page).
Cursor
The cursor coordinates are displayed in the black fields above the
diagram.
• Press the MENU key and click on 'Cursor'.
