The Threshold with Samples trigger uses several measurements to decide when to act. The trigger
can be configured to act quickly, or slowly, depending on the number of measurement samples used.
A new sample is available every 50ms, with the minimum samples being used for a trigger being 1
sample, and the maximum being 20 samples. Threshold with Samples triggers are evaluated every
time a new sample is available. Based on the below "New Trigger" example below, the trigger will
alarm or turn on after 5 of any consecutive 10 samples are above 140V.
Description
Uses the Line to Neutral voltage measurement. Measurement accuracy is between 90
VAC and 300 VAC.
Uses the Neutral to Ground voltage measurement. Measurement accuracy is between
0.6 VAC to 300 VAC.
Uses the current measurement, which includes total product current. Measurement
accuracy is between 0.1 A and 20 A.
Uses the internal temperature measurement. This should not be treated as an ambient
temperature and will vary drastically based on loading.
Uses the frequency measurement. Measurement accuracy is between 45 Hz and 65 Hz.
Uses the average power measurement. Measurement accuracy is between 12 W and
6000W.
Uses the Line to Neutral Voltage Crest Factor.
Uses the Power Factor.
Requires "For" number of measurements to be greater than the threshold.
Requires "For" number of measurements to be less than the threshold.
Requires "For" number of measurements to be exactly equal to the threshold.
Is the number to be evaluated against all measurements to either trigger or clear the
Trigger.
The number of measurements out of the given number of samples being evaluated that
must meet the criteria to trigger or clear the Trigger.
The number of consecutive measurements to be evaluated to trigger or clear the Trigger.
