Does the UNI-T UT33D+ measure AC current?

No, the UNI-T UT33D+ only measures DC current (up to 10A). It is designed to measure AC Voltage (up to 600V), but if you need to measure AC current for heavy household appliances, you will need to upgrade to a clamp meter or a more advanced multimeter model.

What is the difference between the UT33D+ and other UT33 series models?

The UT33D+ specifically features Non-Contact Voltage (NCV) detection, making it ideal for safely identifying live AC wires. Other models in the series focus on different specialties, such as the UT33A+ which includes capacitance testing and auto-ranging features.

How do I use the NCV function on this multimeter?

To use the NCV function, turn the central dial to the "NCV" position and bring the top edge of the multimeter close to the wire or wall outlet you want to test. If live AC voltage is detected, the meter will emit a loud beeping sound and display a visual indicator on the LCD.

Are the batteries and test leads included in the box?

Yes, the UNI-T UT33D+ comes completely ready to use out of the box. The package includes the digital multimeter, a durable protective cover, two high-quality test leads (probes), two AAA batteries, and the operating manual.

Can I get a demonstration on how to test a battery at your store?

Yes, you can bring your batteries or electronic components to Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. Our technical staff will gladly demonstrate how to set the dial to the correct DC Voltage range and properly use the test probes to get an accurate reading.

Full Product Description

Reliable Electrical Diagnostics for DIY and Pros

The UNI-T UT33D+ Digital Multimeter delivers precise voltage, current, and resistance measurements in an incredibly compact and ergonomic form factor. Whether you are troubleshooting a faulty household appliance, testing RC drone batteries, or verifying Arduino circuit voltages, this palm-sized device provides accurate readings up to 600V. Its clear LCD display ensures that your diagnostic data is always easy to read, streamlining your workflow and reducing testing errors.

Built-In NCV for Safe AC Detection

The Non-Contact Voltage (NCV) feature allows you to safely detect live AC wires hidden behind walls or inside conduits without physically touching exposed copper. By simply hovering the top of the UT33D+ Multimeter near a power outlet or cable, the device will alert you to the presence of live voltage via a loud continuity buzzer and visual indicators. This hands-free detection is an essential safety feature for anyone performing household electrical repairs or identifying broken circuits.

Rugged 2-Meter Drop Protection

Encased in a durable, ergonomic red protective holster, this Palm Size Multimeter is officially certified to survive 2-meter drops onto hard concrete surfaces. This precision protection ensures the delicate internal calibration remains intact even if it slips from your workbench or toolbelt. The protective cover also features a convenient test lead hanging groove and a built-in probe holder, keeping your workspace organized and your sharp probes safely tucked away when not in use.

Pro Tip from Our Technicians

Always double-check your dial settings before testing high-voltage AC outlets to prevent blowing the internal fuses. Our Sham Shui Po technical team strongly advises ensuring the dial is firmly set to the "ACV 600V" position before probing household mains power; accidentally leaving it in the DC Current (A) or Resistance (Ω) mode will instantly trigger the internal 250V fuse. To preserve battery life, rely on the meter's Auto Power Off and Auto Backlight Off features during long troubleshooting sessions.
