It also measures power directly — active, apparent, and reactive, with power factor — so you can read load behaviour, not just volts and amps. True-RMS sensing, a low-impedance mode, VFC/VFD mode, loop read, and a Bluetooth app cover the rest of the field set, with AC/DC current to 1000 A and combined AC+DC measurement. It's backed by UNI-T's nearly 40 years of test-meter manufacturing. Key Features Voltage ranges to 2500 V DC / 1500 V AC for PV systems CAT IV 1000 V / CAT III 1500 V safety rating Power measurement: active, apparent, reactive, and power factor True-RMS; combined AC+DC; AC/DC current to 1000 A IP67 sealing and 5 m drop protection Low-impedance (LoZ) mode; VFC/VFD mode; loop read Non-contact voltage (NCV) detection Bluetooth app; relative, max/min, and peak-hold modes UT197PV Details PV Voltage Headroom Raised ranges of 2500 V DC and 1500 V AC keep photovoltaic string and combiner measurements on-scale and within the meter's CAT IV 1000 V / CAT III 1500 V rating, where a standard 1000 V meter falls short. Direct Power Measurement Beyond volts and amps, the UT197PV reads active, apparent, and reactive power with power factor — useful for understanding inverter and load behaviour on a PV or industrial circuit without a separate power meter. Built to Take Abuse IP67 sealing and a 5 m drop rating handle rooftops and harsh outdoor sites, and True-RMS sensing keeps AC accurate on the distorted waveforms around inverters. Field Tools & Connectivity A low-impedance mode rejects ghost voltages, a VFC/VFD mode and loop read cover drive and process work, and a Bluetooth app captures readings to a phone.
