Fuzzy Logging has been developed as a secure data storage technique which has a
self teaching data storage algorithm so the recorder stores data at a variable rate to
match the process being monitored. Fuzzy Logging has intelligent resources to enable
the most effective and efficient way of using the scan rate, storage capacity and record-

ing time.
• Rate Units - Set the Units for the logging rate to be displayed. Select and choose the
logging rate units from the drop down menu.
• Rate - This is the speed at which data is required to be logged.
If the Millisecond option is selected as the Rate Units for the logging, then a drop down
menu of options will appear. When all other Rate Units are selected a keypad will
appear for user entry. Fastest rate is 20mS and slowest is 60 hours.
• Alarm Rate Units - Only available if the logging Type is set to Continuous. Set the Units
for the Alarm logging rate to be displayed. Select and choose the alarm logging rate
units from the drop down menu.
• Alarm Rate - Only available if the logging Type is set to Continuous. This is the new
logging rate used when this pen goes into an active alarm state. To enable this feature
to change the logging rate in an alarm state, see Change Log in the Alarms menu.
If the Millisecond option is selected as the Alarm Rate Units for the logging, then a
drop down menu of options will appear. When all other Alarm Rate Units are selected
a keypad will appear for user entry.
• Method - Only available if the logging Type is set to Continuous. Select from a list of
Methods.
Sample: logs the last sampled reading.
Average: logs the average of all the samples taken since the last log.
Max/Min: logs the highest and the lowest of the sampled readings since the last log.
• Align - Only available if the logging Type is set to Continuous. Select and enter a value
from the list to align the logging at specified intervals. This will hold the start of logging
until the aligned time selected occurs based on the recorders real time clock.
• Auto Fit - Only available if the logging Type is set to Fuzzy. Toggles On and Off. AutoFit
ensures that the last sampled data point is logged before the signal goes out of the tol-
erance set in Band 1 or Band 2. When displayed on a graph, the input signal will auto-
matically fit to this last logged point. This gives a better fit for stepped input changes.
• Band 1 % - Only available if the logging Type is set to Fuzzy. This is where the toler-
ance is set for the input signal. Specify, as a percentage of the scale range, the toler-
ance band allowed above and below the input signal. Select and enter a value.
• Fuzzy Band 2 - Only available if the logging Type is set to Fuzzy. Toggles On and Off.
This is to enable a second tolerance to be set, configure it to be On to activate. Only
used in conjunction with Autofit On, to specify the Band 2 %.
• Band 2 % - Only available if the logging Type is set to Fuzzy. This is where a tighter tol-
erance can be specified which must be set within the limits of Band 1. Specify, as a per-
centage of the scale range, the tolerance band allowed above and below the input
signal. Select and enter a value.
