The UT171B is a 60,000-count True-RMS digital multimeter for plant and process work, rated CAT III 1000 V / CAT IV 600 V. The high count resolves small changes other meters round off, and True-RMS keeps AC readings accurate on the distorted waveforms around drives and switching loads.
It measures DC voltage to 1000 V at ±(0.025% + 5), AC voltage to 1000 V, AC and DC current to 10 A, resistance to 60 MΩ, capacitance to 60 mF, frequency from 10 Hz to 10 MHz, and temperature from -40 °C to 1000 °C. A high-contrast EBTN display, a low-impedance AC mode, and storage for 9999 readings support plant-floor use.
It suits industrial electricians and maintenance technicians working on motor, drive, and switching circuits.
