The
Update Interval is the interval, measured in whole seconds, between successive
records displayed on the codogram. In other words, if you set the update interval to
5 seconds, the codogram display will not update until the after the first complete
measurement following a gap of five seconds. Alternatively, you can set the update
interval to provide the maximum data collection speed by pressing [Max Speed], or
by setting the update interval to 0 (zero) seconds.
NOTE It is not always possible for the analyzer to match the update interval you specify. It
is possible, for example, to set your update interval to zero seconds (the maximum
speed), and then to find that the analyzer can not update any faster than once every
two seconds.
