We have some outlets in our office that we think may be getting current or
voltage surges in the early AM hours. One symptom I see is a UPS
attached to the circuit is reporting constant on and off events. What is
the cheapest way for me to get some direct measurement of this, starting at
the wall plug? I'm hoping someone makes a cheap data logger that would
track voltage and current, so we could see any distinct spiking or surging
activity in a timeline graph.
