Select whether you want to delete the measurement data in
the viasis or not, see also illustration 50.
Also in case the viasis measurement data storage is empty a
file with the file name extension *.VTF (“via traffic format) is
created. The file includes the protocol with event and error
messages, the current parameter setting of the system and
eventually GPS position data.
6.7.2 Checking stored measurement data
A check how much and which measurement data are stored in the viasis you can make by en-
tering
1
for “
Transmit stored data
” in the main menu, see also illustration 11.
If no values are stored the viasis returns immediately back to the main menu, otherwise it re-
ports the number of stored speed values:
Number of values = 21233
It follows the question:
Send data (y/n)?
If you enter
y
the measurement data are send to the terminal, always 25 lines before you are
prompted to continue with <return>:
25;16.12.11;16:52:10
-32;16.12.11;16:52:12
44;16.12.11;16:52:33
38;16.12.11;16:52:35 ...
<Continue with return>
Per line one speed value optional headed by a minus sign indicating leaving vehicle detection,
with date and time, and separated by semicolons is send. If you press any key other as <return>
the output is ended.
After the data output or if you entered
n
for
Send Data (y/n)?
following message appears:
Delete data (y/n)?
If you enter
j
for yes in the terminal all data are deleted, if
N
for no is given the current meas-
urement is continued. In case the ring data storage is full the oldest data are overwritten by the
actual data.
