You want to measure the voltage, amps, and ohms of various devices. What tool would you use? - You'd use a multi-meter. what's a multimeter? - a device for testing various electrical properties. i.e. ac/dc voltage, current (amps), resistance (ohms), capacitance, and frequency. What does a voltage event recorder do? - keeps track of voltage conditions on a power line. basic recorders simply keep track of the occurrence of under/over voltage conditions, while more advanced devices track co...
