Data logging devices are commonplace now days. Many high-end multimeters have such a feature where you can plug the meter up to a power source and record levels over time.
But I'm interested in recording out-of-bounds events such as spikes and sags in mains supply.
This type of measurement is typically only found in power systems analyzers which are quite "$pendy".
Anybody know of an event logger that is affordable?
THanks,
