AstroAI M4K0R Digital Multimeter, Auto-Ranging TRMS 4000 Counts with Battery Test

The AstroAI M4K0R digital multimeter is an auto-ranging TRMS tester for troubleshooting household and automotive electrical issues, with a 4000-count display and measurements up to 600V AC/DC.

• Measures AC/DC voltage to 600V, current to 10A and resistance to 40MΩ — covers a range of common electrical checks.
• TRMS, 4000 counts and auto-ranging — brings these functions together in one meter for taking readings.
• Battery, continuity, diode and live wire tests — supports several types of household and automotive troubleshooting.
• Non-contact voltage detection with sound and light alarms — checks for AC voltage without test leads.
• Double ceramic fuse and CAT III 600V safety standard — adds stated overload protection and safety classification.
• Two 1.5V AAA batteries included — powers the meter without requiring separate batteries to get started.

When you need to investigate an electrical reading, check a battery or look for AC voltage, a meter with several test functions can handle those tasks in one device. The M4K0R is designed for DIYers and hobbyists working on household, automotive or commercial improvement projects.

What measurements and tests can the AstroAI M4K0R perform?

The AstroAI M4K0R measures AC and DC voltage up to 600V, current up to 10A and resistance up to 40MΩ. Its auto-ranging function selects a measurement range automatically, while the TRMS 4000-count display presents readings on the meter’s screen. Use the available functions for checks involving circuits, components and batteries.

• Continuity testing includes an audible buzzer.
• Diode testing checks diodes as part of electrical troubleshooting.
• Live wire testing is available alongside the non-contact voltage function.

How does its battery test and non-contact voltage detection work?

The meter has dedicated battery test modes for 1.5V, 9V and 12V batteries. During a battery test, its indicator turns red for low voltage and green when voltage is sufficient. For non-contact voltage detection, bring the meter near a possible AC signal; when it senses a strong signal, a red indicator lights and the buzzer gives a quick beep. This AC check works without test leads.

• Battery test modes cover three stated battery voltages: 1.5V, 9V and 12V.
• The non-contact function uses both visual and audible alerts.

Which features help during electrical checks?

The AstroAI M4K0R includes Data Hold and Max functions, plus auto shut-off and a low-battery indicator. Data Hold helps keep a reading visible while you note it, and the Max function provides a way to view the maximum reading captured. A backlit LCD screen and flashlight assist when viewing the meter in dim conditions; the continuity buzzer and visual and audible alarms provide additional cues.

• Data Hold and Max are built-in reading functions.
• Auto shut-off and a low-battery indicator are included.
• The package includes two 1.5V AAA batteries.

What safety features does the AstroAI multimeter have?

The M4K0R has a double ceramic fuse designed to resist burnout and protect against overload, and it has passed overvoltage category III 600V safety standards. Its silicone cover is designed to protect the meter from fall damage and help prevent electric shocks. These features accompany its stated 600V voltage measurement limit; use the meter within its specified measurement ranges.

• Double ceramic fuse for overload protection.
• Silicone cover around the meter.
• Overvoltage category III 600V safety standard passed.

This multimeter suits DIYers and hobbyists who want one tool for household, automotive and commercial improvement troubleshooting, including voltage, resistance, continuity and battery checks. Its measurement limits, battery modes and non-contact AC detection make those specific checks available in a single auto-ranging meter.
