After a recording has been made the user will probably want some way to view
and analyze the recorded information. This is most easily accomplished by
printing out the data samples. The printed data can be analyzed or stored for
future reference. Several print options are available.

Filtering Printed Record

If the user were to print a recording which used all of the memory capacity of
the Service Logger this would be a very long record of 4000 data samples. To
print this out line by line on a standard computer printer would use over 60
sheets of paper! Obviously this would be a cumbersome and time consuming
process. In most cases, the information required from the record is only when
the temp-erature or status of the event detector changes. If the temperature or
event detector remains the same, it is not necessary to print line after line of the
same information.

The Service Logger allows the user to select from 1° to 10° of temperature
change or change in the state of the event detector (on to off or off to on) to
print on. What this means is that data samples that are less than the selected
temp-erature change, or if the state of the event detector stays the same, no
samples will be printed until the conditions that are programmed in the filter are
satisfied. That temperature or state of the event detector becomes the new value
to compare to and the temperature or the state of the event detector will have to
change again before another sample is printed.

One important point to remember

 is that even if a data sample is not printed,

the Service Logger still has to recall it from memory and compare it to the filter
selection. Therefore, a printout may take up to 10 minutes for a scan of all 4000
data samples. This may sound complicated, but is easy to understand by using
an example recording.

Example:

A recording has been made in a room of a building over a 30 hour period to
determine whether or not the ventilation fan is turning on when the heat goes
on. This means that a one data sample is recorded every 30 seconds. For the
printout the user has selected a change of 2°. Shown below would be a typical
printout of the data using the above selections. In a real printout there would be
no spaces between the lines of printing, but in our example these were added
to allow room for comments to be inserted.
