    Operation Preliminary Steps Preliminary Steps The Analyzer measures electrical parameters, as described below. These voltages and currents are a natural phenomenon, and their presence within reasonable limits does not constitute a hazard. However, it is necessary to measure their values to determine if there is a significant change from previous measurements or from the device specifications.
