The OLED display gives deep contrast and a wide viewing angle in any light, and the meter adds a square-wave output for testing and calibration alongside the full industrial measurement set. Measurement matches the rest of the series: DC voltage to ±(0.025%+5), AC and DC current to 10 A, resistance to 60 MΩ, capacitance to 60 mF, frequency to 10 MHz, and temperature to 1000 ℃, with True-RMS, a low-impedance ACV mode, and 9999-reading storage. A rechargeable Li-ion pack and 1 m drop rating keep it field-ready. It's backed by UNI-T's nearly 40 years of test-meter manufacturing. Key Features 60,000-count resolution with OLED display Square-wave output for test and calibration True-RMS AC voltage and current; AC bandwidth to 100 kHz DC voltage accuracy ±(0.025%+5) AC/DC current to 10 A; resistance to 60 MΩ, capacitance to 60 mF Frequency to 10 MHz; temperature −40 ℃ to 1000 ℃ Low-impedance (LoZ) ACV mode to reject ghost voltages 9999-reading storage CAT III 1000 V / CAT IV 600 V; 1 m drop; rechargeable Li-ion UT171C Details OLED Display The OLED screen delivers deep contrast and a wide viewing angle that stays legible in bright sun and dim equipment rooms alike — a step up in readability for fast plant-floor work. 60,000-Count True-RMS Measurement The 60,000-count display resolves fine detail, and True-RMS sensing keeps AC accurate on the distorted waveforms around drives and electronic loads where average-responding meters read low. Square-Wave Output A built-in square-wave output supports quick functional checks and calibration tasks in the field without a separate signal source. Safe Measurement & Field Build A low-impedance ACV mode loads out induced ghost voltages so a dead circuit reads dead, the CAT III 1000 V / CAT IV 600 V rating covers distribution work, and a rechargeable Li-ion pack with a 1 m drop rating handles daily use. Compare the UT171 Series UT171B UT171C Display EBTN OLED Square-wave output — Yes Non-contact voltage (NCV) Yes — Applications Plant and process troubleshooting; drive and control-panel work; commissioning and preventive maintenance; and any task where an OLED display and a square-wave output add value to a 60,000-count industrial meter. Frequently Asked Questions What does the UT171C add over the UT171B? An OLED display and a square-wave output. Measurement performance — 60,000 count, True-RMS, ranges, and accuracy — is the same. Is the display readable outdoors? Yes — the OLED screen holds contrast across viewing angles in bright and low light. Is it True-RMS? Yes, on both AC voltage and current.
