The tree on the left side of the Log Configuration On dialog box contains 7 nodes. Within
each of these nodes are data points that can be logged. Many of these data points are static
or rarely changed values that should not need to be continuously logged. The data points of
the most interest are stored in the two nodes called Input/Output and Alarm/Status.
• Input/Output contain data points such as the current concentration readings for all stream
types (normal, calibration, reference, and zero), the gain, status of various alarms and
latches, and the status of discrete inputs and outputs.
• Alarm/Status contains data points such as the live sensor output, hourly and daily minima,
maxima, and averages, and the tape remaining.
To expand any node, simply left click on the (+) icon to the left of the node label. This will
expand the node to show all of the data points within that node. To put any data point into a
log, left click on the data point of interest, and while holding the right mouse button down,
drag the data point into the desired log. Once the left mouse button has been released, the
data point should become a row in the table for the log, and the change to the log
configuration will be automatically written to the analyzer. If the data point is in Log Periodic
1-3, ensure that a frequency is entered for the data point.
Changing the frequency time within a given periodic log will cause all the
frequency times in that log to change to the same value.
To remove a data point from any log configuration, simply right click on the row to be
removed, and then select the Delete Item option from the popup menu that appears. Once all
the desired changes are made, click on Read from Unit to ensure that the changes have
correctly written to the unit, and then click on the X in the top right hand corner to close the
Log Configuration window.
