The degree of compression of the measurement data on the screen is given as
a ratio in steps (1:1, 1:2, 1:5, 1:10, 1:20, 1:50 and 1:100).
For instance, 1:100 means that 1 screen pixel corresponds to 100
measurements.
Search criteria Several search criteria can be employed in the search for values:
- Limitation to a time period within the stored measurement data.
If no comparison operator is defined, a search is made for the set start time.
The measurements are shown, as far as they are available.
- Comparison of the measurements of a channel against a comparison value.
If the search has been successful, the position is shown in the center of the
screen, below the cursor.
- Combination (AND, OR) of the measurement check on a channel with a
second measurement check on the same or another channel.
