UPS power terminology is a little more arcane than other computer terminology you might be probable much more knowledgeable about, having said that, so it pays to know how the number of volt-amperes interprets into battery runtime based on the hardware You will be plugging in to the UPS.
Illustration #seven - you forgot the -jar choice when trying to run an executable JAR file, and the java command has misconstrued the JAR file title as a category title
That is ample distortion to show up in the oscillogram on the still left: discover the somewhat flattened peaks.
