Uploading logged data from the WEATHERPAK
The Data Retrieval Menu lets you upload and inspect data being collected by the WEATHERPAK. Type
D
from
the user menu to enter the
DATA
retrieval menu. The WEATHERPAK stores sensor data as a set of data records:
each data record consists of a time stamp and one or more processed sensor data values. You may have seen the
processed sensor data values being output to the terminal before entering the User Menu.

You cannot change anything from the data retrieval menu. The following data retrieval commands are available.
A
Show records
AFTER
specified time. This option lets you examine a fixed number of records, starting at a
given time. For example, you may wish to examine the next 3 records logged after 3 p.m. You will be
prompted to enter the start time, and the number of records to be displayed. Be sure to enter the start and
end times in the format “YY/MM/DD HH:MM:SS”; for example, 94/11/28 14:45:00. Hit the space bar to
halt the display; you will be prompted for confirmation.
B
Show all records
BETWEEN
timespan. This option lets you examine all records logged between a defined
start and end time -- you will be prompted for the start and end time if you make this choice. Be sure to
enter the start and end times in the format “YY/MM/DD HH:MM:SS”; for example, 94/11/28 14:45:00. Hit
the space bar to halt the display; you will be prompted for confirmation.
C
Compute data logging
CAPACITY
. The terminal will show the total memory available for data storage, the
total number of data records that can be stored, and the total time taken to fill the data logging memory.
N
Show
NUMBER
of records logged. The terminal will show the number of data records that have been
collected and stored in memory. This value must be less than or equal to the data logging capacity.
D DELETE
all data records from the data logging memory. You will be prompted for confirmation.
Ln
Show
the
LAST n
data records. For each data record, the terminal will show the date and time stamp,
followed by the logged, processed, sensor data values. The display will look something like this (assuming
relative humidity and air temperature are being measured). The detailed format of the display (e.g., whether
commas or spaces separate the data values) can be changed from the System Functions menu (choose
S
from the user menu). Hit the space bar to halt the display; you will be prompted for confirmation.

@n
Show
n
unmarked records. The data retrieval menu lets you “mark” logged records as already having been
read. The first time you enter
@n
, the WEATHERPAK will display the oldest
n
records. If you
subsequently enter
M
, these records will be marked as read. You will no longer be able to access these
records using the
@n
command, although they will be accessible using the
L
(show last records),
J
(show
records between specified times), and
K
(show records after a specified time) commands. The next time
you enter
@n
, the WEATHERPAK will display the oldest unmarked
n
records.
M
MARK
recently shown data. This command marks as read the last set of records displayed using the
@n
command. This command will work irrespective of when the last
@n
command was used -- even if you have
left and re-entered the user interface in the mean time.
*
Show all data records. You will see all the records logged to date sequentially, in the same format as the
above. Hit the space bar to halt the display; you will be prompted for confirmation.
