Setting the Log Interval
The LOG INTERVAL is the time interval
used between recorded data points during
Manual Mode logging operations (log
intervals for Prog-1 through Prog-5 are set
using TrakPro
™ Software). For example, if
the LOG INTERVAL is set to 30 seconds, a
data point is stored to memory once every
30 seconds. Longer Log Intervals can be
used to conserve memory for long
duration tests.
The SidePak
™ AM520/AM520i always makes a measurement once
every second regardless of the log interval selected. Using a log
interval greater than one second results in stored data points that are
averages of the 1-second readings. For example, a 10-second log
interval will result in one stored data point every 10 seconds. Each of
those data points will represent the computed average of ten,
1-second readings.
N O T I C E
LOG INTERVAL is user adjustable from 1-second to 1-hour
(60 minutes). It is recommended for test lengths
≥2 hours that log
intervals of
≥30 seconds be used to avoid logged tests with
excessive amounts of data points.
DO NOT mistake log intervals with Time Constant. Log intervals only
affect recorded readings. Time Constant only affects the
AM520/AM520i OLED display.
Five log intervals choices are preprogrammed. This list of available
log intervals can be modified using TrakPro
™ Software.
