Data Log Destination:
Options are logfile, printer or both. When the logfile option is selected, the logfile
is located at /flash/datalog.csv. The maximum allowed size for this file is roughly
one megabyte. If the file reaches this size, logging is halted.
Select Data Log Items:
Press this key to access the Data Log Items sub-menu, which provides keys for
fifteen items that can be individually selected for logging. By default, both the
bucket and jacket temperatures are logged. All records are date and time
stamped. The most commonly helpful items to log are:
D0 - Corrected calorimeter drift rate.
Tsum - Accumulated temperature rise.
T1 - Extrapolated temperature rise.
C0 - Temperature conversion counter
Data Log Format:
Toggles between Text Format and Data Format (csv). Data is either logged with the
supporting tag information (text) or in a comma separated variable (csv) data format
as selected by the user. The text setting is useful if the data log destination is a
printer. The data (csv) format is especially useful if the data is ultimately transferred
to another computer for post processing, graphing etc. The log file can be transferred
to another computer via FTP.
Delete Data Log File:
When this key is pressed the contents of the data log file are deleted.
View System Log:
This key accesses its sub-menu which displays the contents of
/flash/log/messages. This file is used primarily to log application program debug
messages. Press the Print key to print these messages.
User Defined Functions:
This key leads to a sub-menu that offers five special purpose user/ factory definable
function keys.
Combine Det. Reports:
Pressing this key combines all determination reports into a single file named
/tmp/bigdetfile.txt.
Combine Std. Reports:
Pressing this key combines all determination reports into a single file named
/tmp/bigstdfile.txt.
Logged Data to SD:
Copies the internal data log file to an SD card inserted into the back of the
calorimeter.
