Description
upon occurrence of new events, but is not to exceed 60 seconds.
min = 0.5; max = 60.0; block= 0.3
Note
You should only use the signal frequency trigger on one of the conductors, since the
capacity of the device hard drive will otherwise be exhausted too quickly.
Triggered signals can lead to data glut if the trigger is released often. For this reason it's
recommended for long measurements to work without a trigger and to instead capture the
disturbance source as interharmonics. The reduced signal enables equally good qualitative
evaluation.
In particular with the curve comparison trigger, it is recommended to take a test
measurement in order to check the value limits which have been set. Due to the finite
sampling and to frequency fluctuations, there is a measurement uncertainty of more than 5
%. Currents are subject to even greater fluctuations.
The amplitude of the signal frequency is at first saved continuously as a curve plot and
aggregation. Therefore it's absolutely necessary to specify the frequency.
