Power and distribution panels and their nearby wiring are a frequent starting point for technicians when electrical disruptions require troubleshooting. Voltage and current are two of the most common electrical measurements taken at panels and the surrounding wiring. To isolate specific problems, a technician may also want to test for continuity or measure peak voltage, peak current, minimum/maximum voltage (or current) over time, temperature, harmonics, power factor, transient voltage, temperature...
