Portable Frequency Meters are typically designed to measure frequency ranges from 40 Hz to 70 Hz or wider, depending on the model. They feature digital LCD or LED displays with high-resolution readouts and are powered by internal batteries or rechargeable Li-ion cells. Input voltage range generally supports up to 600V AC, with overload protection and signal conditioning circuitry for safe operation in harsh environments. Measurement accuracy is often within ±0.1 Hz, with fast response time and noise filtering capabilities. The instrument includes features such as auto-ranging, data hold, low battery indication, and sometimes logging or USB interface for data export. The rugged housing is designed to withstand field conditions and comply with IEC 61010 safety standards, ensuring electrical and operator protection. These meters are commonly used in power plants, substations, generator testing, inverter output validation, and frequency-sensitive equipment calibration
