Fast measurement records dynamic pressure proces-

ses. These can occur unexpectedly. In some circum-
stances large volumes of data can be created during
recording, even though there is no event. The trigger
function can be used to define a rule that filters out
the interesting data material. These data are stored
separately and visibly in individual mutually indepen-
dent logs. The software shows the monitoring log and
several snapshot pages. All logs are presented as line
diagrams. They are displayed on registers.
The monitor time window shows the measured data
with a time offset (approx. 2 s) for measurements in
the handheld instrument.
The monitor log runs for as long as the fast measure-
ment mask is visible. The monitor can be paused with
the pause function, but recording will continue. Once
the pause is over, the data recorded in the meantime
will be presented.
The monitor log is discarded on closing.
Measuring rate 25/sec.
