different colours:
•
First marking:

•
Third marking:
blue

Time diagram:
This graph shows the R

-values over time. This allows
for visual control of the measured marking.
Signal quality:
Visually indicates the signal quality of the measured
data. A full green bar means good signal quality. Note:
Despite this bar showing bad quality for short periods,
the measuring result still may be fine. Only if the bar is
empty all the time this indicates a bad signal caused by
vibrations, electrical fields or other interferences.
