Pressing F1 enables the user to communicate with the WRL using all the
commands referred to in the
Communicating with the WRL
(page 14)
Section
of this manual.
Pressing F2 instructs the computer to retrieve data from the WRL and place
that data in a file on the disk drive. Only new data will be written to disk during
successive retrievals. Any number of WRL’s or WPS’ can be accessed and
their data will be put in different files on the drive. There will be two files written
on to your drive, log_day.??? and log_rec.???. Log_day. ??? has the
minimum and maximum values and log_rec.??? has the individual records.
Each file has a file extenuation that corresponds to the ID number of each
weather unit. The ID number can be changed through the calibration (F5)
routine in Twi_Log. For example if you downloaded data from a unit with the ID
of
124
the data for that unit would be found in
log_rec.124
.
Pressing F3 displays the data written on disk. Press the up arrow key to go up
or down one record at a time, press the page up or down keys to display one
screen of data at a time, press the home or end key to go to the top or bottom
of the file. The delete key takes all records prior to that displayed at the top of
the screen and transfers that data to an archive file arc_log.??? file. The
extension ??? will be the same as the unit number. The data that is archived is
removed from the current display and log file.
Pressing F4 purges any duplicate data written on disk.
