Simple Logger
®
II Series

The logger will store on event, which means that if there is no change at
the input of the instrument, it will not store any data until the next event
cycle occurs. This happens when the instrument sees the changes at an
input, as previously described.
If the expected event rate is 1s, then it would be necessary to set the
sample rate faster than once per second in order to capture the events.
As mentioned previously, the timing accuracy of the captured event is
dependent on the sample rate. The faster the sample rate, the higher the
timing accuracy.
Minimum duration of an event will need to be the duration of the sample
rate such that if the sample rate is 125ms, then the pulse will need to be at
least 125ms to be certain that the logger will capture the event.

The above example assumes that the “Invert display polarity (event
displayed as a high)” is selected from the scales tab of the configuration
(default setting).
