Smart Digital Multimeter for Electrical and Automotive Testing

Simplify everyday electrical troubleshooting with the LJPXHHU MY8331 Smart Digital Multimeter. Featuring intelligent auto-ranging, True RMS AC voltage measurement, non-contact voltage detection, and an easy-to-read backlit screen, this compact electrical tester is designed for home maintenance, electronics projects, and automotive diagnostics.

Automatic AC/DC Voltage, Resistance & Continuity Testing

The smart auto-ranging function automatically identifies supported measurement types and selects an appropriate range, reducing the need to change settings manually.

  • AC/DC Voltage: Measure voltage up to 600V within the supported range.

  • Resistance Testing: Check resistance across supported measurement ranges.

  • Continuity Testing: Use the audible buzzer to identify connected circuits.

  • Battery Testing: Check the voltage of 1.5V, 9V, and 12V batteries.

True RMS & Non-Contact Voltage Detection

True RMS technology supports AC voltage measurements, including applications involving non-sinusoidal waveforms.

The built-in NCV (Non-Contact Voltage) function helps detect the presence of AC electric fields without directly touching a conductor. Audible and visual alerts make preliminary voltage checks more convenient.

NCV is an indication feature and must not be used as the sole method of confirming that a circuit is de-energized.

Backlit Display & Built-In Flashlight

The illuminated digital display helps you read measurements in dimly lit areas. A built-in flashlight provides additional visibility when working around equipment or in darker workspaces.

Convenient features include:

  • Data Hold for retaining a displayed reading

  • Low-battery indicator

  • Automatic power-off after approximately 15 minutes

  • Simple button-based operation

Compact Design for Everyday Use

The orange protective housing offers a comfortable, secure grip while helping protect the instrument from everyday bumps. Its compact size makes it easy to carry in a toolbox or store in the included drawstring pouch.

What's Included

  • 1 × MY8331 Smart Digital Multimeter

  • 1 × Pair of Red and Black Test Leads

Frequently Asked Questions

What can the MY8331 smart digital multimeter measure?
The LJPXHHU MY8331 supports AC/DC voltage measurement, resistance testing, audible continuity testing, and battery voltage checks. It also includes an NCV function for detecting the presence of AC electric fields.
Does this digital multimeter automatically select the measurement range?
Yes. The smart auto-ranging function automatically selects an appropriate range for supported measurements, making everyday electrical testing more convenient without manual range selection.
Does the MY8331 multimeter support True RMS?
Yes. The MY8331 includes True RMS technology for AC voltage measurement. This helps provide meaningful readings when testing supported non-sinusoidal AC voltage waveforms.
Can this multimeter test car batteries?
Yes. The MY8331 can be used to check the voltage of compatible 12V automotive batteries, as well as 1.5V and 9V batteries. Voltage readings help with preliminary battery checks but do not replace a dedicated battery load or health test.
What is the NCV function on this multimeter?
NCV stands for Non-Contact Voltage. It detects the presence of an AC electric field without direct contact with a conductor and provides visual or audible alerts. NCV does not measure exact voltage and must not be relied upon alone to confirm that a circuit is safe to touch.
What comes with the MY8331 digital multimeter?
The package includes one MY8331 digital multimeter, a pair of red and black test leads, two AAA batteries, a drawstring storage pouch, and a user manual. The backlit screen, flashlight, and data hold function are built into the meter.
