Brightness and signal colors depend on the cumulative frequency of the value. See:
"To configure brightness" on page 56
● Waveform as line or points: see "To set the waveform style" on page 57.
To configure intensity
For optimal contrast, you can change the intensity of the waveform, of the grid, and of
the backlight.
1. Press "DISPLAY > Intensities".
2. To set the intensity of the waveform:
a) Press "Waveform".
b) Enter a percentage between 0 (not visible) and 100% (very strong). The default
value is 50%. You can also use the "INTENSITY" knob on the left side of the
screen to adjust the waveform intensity directly.
3. To set the intensity of the grid:
a) Press "Grid".
b) Enter a percentage between 0 and 100%. The default value is 34%.
4. To set the intensity of the backlight:
a) Press "Backlight".
b) Enter a percentage between 10 and 100%. The default value is 50%.
To configure persistence
1. To display only the current signal at any time, press "DISPLAY > Intensities > Per-
sistence" until "Off" is highlighted.
2. To have the instrument define the optimal persistence automatically, press "DISPLAY
> Intensities > Persistence" until "Automatic" is highlighted.
3. To configure the persistence manually:
a) Press "DISPLAY > Intensities > Persistence" until "Manual" is highlighted.
b) Press "DISPLAY > Intensities > Persist. Time" to define the persistence time.
c) Enter a value between 50 ms and 9.6 s or "Infinite".
Each new data point in the diagram area remains on the screen for the defined dura-
tion. If "Infinite" is selected, each new data point in the diagram area remains on the
screen infinitely until this setting is changed or the persistence is cleared.
4. To update the waveform, press "DISPLAY > Intensities > Clear Persist.".
To configure brightness
For better distinction of rare and frequent values, you can apply a color range to the value
frequency. With this color range, rare values are displayed in blue, while more frequent
values are red and very frequent values are displayed in yellow or white, with various
colors inbetween.
