The lower left area of the Log File Properties screen shows the current Tasks that will be logged,
their order, the rate of their logging, and any function that may be applied to their value.
Task Options: Tasks can be added, edited, and removed from the log file configuration with the
options provided here. Some options may be grayed out if a Task is not selected. Only selected
Tasks may be modified or deleted. Use the Add Task button to add an existing Task or the
DATE or TIME variables to a log file. The Remove Task button removes the selected Task from
logging. Any previously logged values will remain in the log file but new measurements will not
be logged.
Task Priority: The priority of Tasks can be changed through use of the Move Up and Move
Down buttons. The order of the Tasks indicates the order in which they will be executed, from
top to bottom. All Task Inputs are run first, followed by all Task Outputs, both according to
Task Priority. Move the selected Task up one level. Move the selected Task down one level.
The Edit Task button allows additional processing functions to be performed on Task values.
The outcome of these functions do not affect the original Task values and only apply to the
values being logged.
Use: Most functions have a USE option defining the number of values that the selected function
should be performed on. If All is selected, all recorded values (up to the last 200) will be used
with the selected function. If Prev.
n Measurements is selected (where n is any desired number),
the current value and previous n - 1 values are used. For example, if a running average of the
past hours worth of data is wanted and the Task is set to scan every 15 minutes, setting the USE
to Prev. 4 Measurements would properly accomplish this. If only the top of the hour should
compute the past hour’s average, setting the Log To File to a Timed Rate of an hour (01:00:00)
would achieve this.
