Log Data Format
A log entry is generated at the time described in the setup file. When
entries are retrieved with the
logshow
command, the produced output
includes two parts: the header and the log entry information.
An example of a log query shows 4 entries of logged items 2, 3 and 4
starting at 10 o'clock on December 28, 1998:

The header information shows the log parameter number (17, 18 and
19) and the variable name (average dew point, - relative humidity and
- temperature).
The log entry information includes the time tag (date and time) of the
entry, the status, and the value of the logged measurement/calculation.

Controlling Logging
Logging is automatically on if it has been defined in the setup and if it
has not been stopped. The logging needs to be stopped when:
- Today's log file is retrieved.
- A sensor is replaced (if some invalid log items can be tolerated,
stopping is not necessary).
