The UNI-T UT890D+ True RMS Multimeter is a professional, manual-range True RMS digital multimeter designed for precision electrical maintenance, PCB troubleshooting, and automotive electronics. Featuring a large 6000-count backlit LCD display, it measures AC/DC voltage up to 1000V/750V, AC/DC current up to 20A, capacitance up to 100mF, and resistance up to 60M$Omega$. It comes equipped with Non-Contact Voltage (NCV) detection, LIVE line testing, hFE transistor testing, and blown-fuse visual/acoustic alarms.
True RMS Measurement: Delivers reliable, accurate AC voltage and current readings across non-linear and distorted circuit waveforms.
Heavy-Duty 20A Current Capacity: Measures up to 20A AC/DC, making it suitable for automotive starter/charging diagnostics and high-draw industrial loads.
Massive 100mF Capacitance Range: Fast-response capacitance mode allows direct testing of large motor-start and power supply filter capacitors up to 100mF (100,000μF) in under 12 seconds.
Non-Contact Voltage (NCV) Detection: Features multi-segment visual and audible alarms to detect live AC voltage through walls or insulation without physical contact.
LIVE Neutral/Live Wire Test: Easily distinguish between Live and Neutral wires using a single test probe with clear acoustic and visual indicator prompts.
Fuse Detection & Overload Protection: Built-in acoustic-optic alarm warns if an input fuse is blown or current limits are exceeded.
Max/Min & Relative (∆) Modes: Capture peak fluctuations or zero out test lead resistance for low-ohm testing.
Ergonomic Workshop Build: Equipped with a bright LCD backlight, data hold, auto power off (with disable option), integrated test lead holders, and a sturdy tilt kickstand.
