6. Operation
In contrast in the mode "continuous value logging" the measured value are
automatically stored continuously into the log. This mode is suitable to
record traces over longer periods of time.
A click on the button "start" starts the recording of measured values. With a
click on "stop" the recording is halted. By clicking "start" again the logging
can be continued. The new measured values are appended to the existing
log.
To reduce the amount of data at long time recordings it is possible to write
only every x-th value to the log. X can be set between 1 (take every
measured value) and 10,000. The logging cycle given by measuring time
and setting of x is displayed at the window. In that way intervals between
100 ms and barely 3 days can be set.
By checking the check box "log overload" it can be determined if an
"overload" is written to the log file in case of exceeding the measuring range
or if no value is logged in this case.
Switching between the modes "single value logging" and "continuous value
logging" is possible at any time. New measured values are always
appended to the existing log.
The software shows a preview of the log with the last 20 stored values. At
this preview the last logged value is at the top.
With the button "clear log" the existing log can be erased.
With the button "save loge" the recorded log can be stored. The log is kept
in the program so it can be continued afterwards.
