UNI-T UT33D+ Palm Digital Multimeter

Overview

The UNI-T UT33D+ is a palm-size multimeter for bench work, appliance repair and routine electrical checks. It covers DC voltage up to 600 V, AC voltage up to 600 V, DC current up to 10 A and resistance up to 200 MΩ, in manual ranges that you select on the rotary switch.

The built-in NCV sensor gives a quick warning of live AC wiring before you touch a cable or socket. Data hold, a backlit display and automatic power-off make it practical for work in cramped or dim places.

Key Features

• 2000-count (1999) backlit LCD

• Resistance from 200 Ω to 200 MΩ
• Diode test and continuity buzzer
• Non-contact voltage (NCV) detection
• Data hold and automatic power-off
• Rated CAT II 600 V
• Runs on two AAA cells

Typical Applications

• Checking power supplies, adapters and batteries
• Fault-finding in electronics, appliances and vehicle wiring
• Continuity and diode checks on PCBs and cables
• Locating live wires before electrical work
• Student and hobby electronics labs

Important Notes / Safety

• The meter is rated CAT II 600 V. Do not use it on circuits above 600 V or on distribution boards and supply mains (CAT III/IV locations).
• Select the correct function and range before connecting the probes, and move the red lead to the 10 A socket only for high-current measurements.
• NCV is an indication only. Always confirm a circuit is dead with a proper voltage measurement before working on it.
