Electrical instruments are instruments that use the mechanical movement of electromagnetic meter to measure voltage, power, current, to mention but a few. Electrical technicians require electrical measurement equipment to check the electrical activity and to detect the presence of voltage or current. By using this instrument you can measure electrical parameters such as voltage, frequency, current, power factor, and resistance. Electrical measurements are dependent upon either current or voltage while measuring the frequency you will be measuring the frequency of a current signal or a voltage signal.
