Data Logger Controls
Data Logger: This key toggles the data logging
function ON/OFF.
Data Log Interval: This key displays the inter-
val of which the selected data is logged. The
interval in seconds is defined in the Select
Data Items sub-menu (normally 12 seconds).
This roughly matches the update interval for
the bucket temperature.
Data Log Destination: Options are logfile,
printer or both. When the logfile option is se-
lected, the logfile is located at /flash/log/data-
log.csv. The maximum allowed size for this file
is roughly one megabyte. If the file reaches
this size, logging is halted.
Data Log Items
Select Data Log Items: Press this key to access
the Data Log Items sub-menu, which provides
keys for fifteen items that can be individu-
ally selected for logging. By default, both the
bucket and jacket temperatures are logged. All
records are date and time stamped. 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 use-
ful 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.
