11 Description of device functions Prosonic Flow 92
78 EHauser
The functions described below are available in the operating mode “START LOG”.
Data logging is started by selecting the appropriate set of data with the log's definition in the selection
table by means of the
W
and
V
keys and then pressing the “ENT” key once.
Note!
• Date and time entered must be future values because the start of logging will be triggered by passing
the starting values. If the start values are defined for values in the past, recording will not start.
• A “
✓
” displayed in the “Data” column indicates that a stored set of log data is already present at the
number in question. It is not possible to restart this log again by means of “START LOG”. First define a
new data set or delete some of the data sets already existing.
• If the notice message “Sample not selected!” appears on the screen during the start, the definition of
the log is faulty or invalid (e.g.: none of the variables has been selected for recording). If this occurs,
verify the definition of parameters by means of the function “SETUP”.
• If the notice message “Out of Memory !” appears on the screen during the start, the recording data set
exceeds the maximum storage capacity of the data logger's memory. If this occurs, verify the definition
of parameters by means of the function “SETUP” and erase any earlier log data from memory.
• While recording is in progress, it is possible to exit the group data logging by means of the “ESC”
button without interrupting the logging process.
• After logging is completed the display screen will automatically switch to the group “DATA LOGGER”.
Information Field An information field is displayed in the upper section of the graphic screen
display. It shows the following information about the recorded and saved log
data: log name, start date/time, end date/time and measurement interval.
Status Display While logging is in progress, the data logger displays the message “Data
Logger Sampling” in the centre of the graphic screen.
Continue The cursor is always set to the default position “CONTINUE” to prevent a log-
ging process in progress from being stopped accidentally.
Stop Sample Use this function to abort a log in progress before the end date/time has
actually expired.
Note!
If a log in progress is aborted, all recorded data are saved up to the point
where logging was terminated.
