Pen related setups
Select each pen from the list and allocate information about that
pen by going through the tabs at the top of the screen.
Click in any area on the screen and press F1 on the keyboard to
display the related help files.
General
In the
General
tab select and enable each pen required, allocate a name or tag and a
description. There is an option to set the pen trace thickness and a comprehensive colour
palette to modify the pen trace colours on the graph. The pen trace colours are identical
to those in the recorder.
Scales
Enter information about the scale by filling in the unit of measurement from the
Unit
Text
drop down menu, or use manual text entry. Set the
Zero
and
Span
details for the
bottom and top scale limits which can be up to 7 digits in length. The scale displayed in
this window will incorporate zero, span and division changes according to information en-
tered.
Divisions
within the scale can have increments automatically entered or the
Ma-
jor
and
Minor
divisions can be set manually.
Scale factor
is the scale value multiplier
which allows very large values to be displayed. Use the
Format
button to specify auto-
matic scale label formats and to define the number of decimal places, default is 2.
Logging
When enabled, logging mode is set to normal and data can be logged to disk or to the
PC card, (if fitted).
Logging type
can be set to none, continuous or fuzzy. For more de-
tails see
“Fuzzy Logging” on page 17.
The
Logging rate
is to be set using the drop down menu. Specific intervals can be
fixed using the
Concise
option. There are three
Logging methods
to choose from
Sample
,
Average
or
MaxMin
.
Sample
will log the actual value of the last sampled
reading,
Average
will take an average of all the samples taken since the last log, and
MaxMin
will log the Maximum and Minimum values since the last log.
Fuzzy Logging
Fuzzy Logging has been developed as a secure data storage technique which has self
teaching data storage algorithm so the recorder stores data at a variable rate to match
the process being monitored.
For more information see
“Appendix B - Fuzzy Logging” on page 81
.
When
Fuzzy Logging
is selected the set up screen will change. A base rate is re-
quired, this is the rate at which the Input signal is checked. Specific intervals for logging
can be fixed using the concise button.
To keep logging to a minimum, optimise disk space and to have more accurate wave-
forms, tick the
Autofit
box.
Advanced Users Only
Fine tuning - Band A. Set up a percentage by which the input signal must change to
trigger a log.
Band B is a more specific band within Band A, to give a more accurate trace.
