Operation 25
After selecting Log Interval from the Setup Menu, the display will
show LOG INTVLx where "x" is a number from 1 to 5. This is the
currently selected log interval. The value of that log interval is shown
on the second line.
Use the ▲ ▼ keys to scroll through the available log intervals. Press

when the interval you want to use is displayed. The factory-preset
choices are:
•
Log Interval 1: 1 Sec.
•
Log Interval 2: 1 Min.
•
Log Interval 3: 5 Mins.
•
Log Interval 4: 15 Mins.
•
Log Interval 5: 30 Mins.
Setting the Time Constant
The TIME CONSTANT is used to
dampen fluctuations in the displayed
readings and make them easier to read.
The TIME CONSTANT setting affects
values shown on the instruments display
only.
DO NOT mistake Time Constant
with logging intervals. Time Constant
only affects the displayed information
(i.e., it is a moving average of mass
concentration). Log intervals only affect
recorded data.
The SidePak
™ AM520/AM520i always makes a measurement once
every second and updates the display every second regardless of the
Time Constant selected. Using a Time Constant greater than one
second results in displayed readings that are averages of the
1-second readings. For example, a 10-second Time Constant will
cause the display to show an average of the most recent ten
1-second readings. In other words it is a 10-second "moving
average," updated every second.
There are five preprogrammed choices for Time Constant. If
necessary, the list of available Time Constant may be permanently
altered using TrakPro
™ Software.
