It measures AC/DC voltage and current to 1000 V and 10 A, combined AC+DC, resistance, capacitance, frequency, and temperature to 1000 ℃, and pairs to a Bluetooth app. Working tools include a low-impedance (LoZ) mode, low-pass filter, VFC/VFD mode for drive outputs, a loop-read function, conductance, and duty cycle — the functions plant and field electricians reach for. It's backed by UNI-T's nearly 40 years of test-meter manufacturing. Key Features CAT IV 1000 V safety rating IP67 sealing and 5 m drop protection True-RMS; AC/DC voltage and current to 1000 V and 10 A; combined AC+DC Low-impedance (LoZ) mode to reject ghost voltages VFC/VFD mode and low-pass filter for drive outputs Loop-read function for process work Resistance to 60 MΩ, capacitance to 60 mF, frequency, temperature to 1000 ℃ Bluetooth app; relative, max/min, and peak-hold modes UT197 Details Built to Take Abuse A CAT IV 1000 V rating, IP67 sealing, and a 5 m drop rating put the UT197 in a different durability class from typical handhelds — it keeps working after dust, water, and falls that would end other meters. True-RMS & Drive Tools True-RMS sensing keeps AC accurate on distorted waveforms, while a VFC/VFD mode and low-pass filter let you read the fundamental cleanly on variable-frequency-drive outputs. Safe & Process-Ready Measurement A low-impedance mode loads out induced ghost voltages so a dead circuit reads dead, and a loop-read function supports 4–20 mA process measurement alongside the standard electrical set. Range & Connectivity Combined AC+DC measurement, temperature to 1000 ℃, and a Bluetooth app cover a wide range of field tasks and let you capture readings to a phone.

Frequently Asked Questions How rugged is the UT197? It is rated CAT IV 1000 V, sealed to IP67, and rated for a 5 m drop — built for harsh field use. Can it read variable-frequency drive outputs? Yes — a VFC/VFD mode and a low-pass filter let you read the fundamental on a drive output. How is the UT197 different from the UT197PV? The UT197PV is the solar version: higher voltage ranges (2500 V DC / 1500 V AC) and built-in power measurement for PV work.
