PRINTING RECORDED DATA

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 out 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 temperature or pressure changes. If the temperature or pressure remains

constant, 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 1 to 10 PSI (0.0 to 1.0 BAR) of pressure change to print on. What this

means is that data samples that are less than the selected temperature or pres-

sure change are ignored during the printing process and only when the tem-

perature or pressure has changed by the selected amount is a sample printed

out. That temperature or pressure becomes the new value to compare to and

the temperature or pressure will have to change again by the selected amount

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 of water temperature and pressure over a 30 hour

period. This means that a 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 will be no

spaces between the lines of printing, but in our example these were added to

allow room for comments to be inserted.
