## Description

Product description

Review: Inexpensive, works well, easy to use, accurate - very happy with this meter - Very pleasantly surprised by this inexpensive multimeter. I was not expecting a lot but was quite happily surprised by the ease of use, the large number of features, and the accuracy of the voltage, current, capacitance, and resistance measurements. It is compact and has good fit and finish. It is 4000 counts meter which is fine for electronics hobbyist use. For a beginner multimeter user, an electronics hobbyist, or just to have a spare meter, this is pretty nifty. The NCV feature is handy. The set of test probes seem to be of decent quality and come with those little plastic covers that cover everything but the tips (to prevent accidental short circuits).
Review: Great Budget-Friendly Multimeter for Basic Electrical Troubleshooting - This looks like a strong choice for someone who wants a multimeter that covers the main functions without paying a lot. Auto-ranging, continuity, capacitance, battery checks, and NCV make it feel like a useful all-around tool for home, automotive, and light electrical troubleshooting. AstroAI has a decent reputation in the budget tool space, and this seems like a good fit for someone who wants practical features without going full professional-grade. Pros: ✅ Good range of useful functions ✅ Auto-ranging makes it easier for beginners ✅ Nice for household and automotive troubleshooting ✅ Good budget-friendly tool Cons: ⚠️ Better for general-use testing than specialized advanced electrical work ⚠️ As with any meter, leads and user knowledge still matter Overall, a solid multimeter for everyday troubleshooting.

## Features

- Wide application - The AstroAI M4K0R Multimeter accurately measures AC/DC voltage to 600V, Current to 10A, Resistance to 40MΩ. You can use it for continuity test, diode test, battery test and live wire test. Includes 1.5V, 9V and 12V battery test modes to easily test a wide variety of batteries. Multimeter light turns red for low voltage and green for enough voltage.

## Questions & Answers

**Q: How sensitive is the NCV feature?**
A: I called it a name and it still works.   It detects LED voltage on Christmas tree lights from about 5 inches away...
you may find your meter has feelings, but mine seems to not care about sensitivity.. it just indicates voltage is present.

**Q: Do the Battery Test selections test under load?**
A: The M4KOR model does the 1.5v - 9v - 12v battery tests each is under a small load, and does test the battery voltage as part of the DC volts ranges.
 
The M6KOR model does NOT perform battery tests under load, but does test the battery voltage as part of the DC volts ranges.

**Q: Would you choose this model or another for automotive diagnosing?**
A: To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke

**Q: I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty?**
A: Make sure you have the leads in the proper slots or ports for the amperage reading.

### ⭐⭐⭐⭐ Good multimeter, especially for the price
*by A***Z on July 19, 2023*

I purchased this meter as a back-up. This is an inexpensive multimeter that comes with a few extra features. Beyond the typical VDC, VAC, mA, Amps, Resistance and Capacitance readings, it also provides Non-Contact AC Voltage (NCV) and Live Wire AC Voltage detection. The construction is solid. The display backlighting is strong and works well. Note that the NCV detection is fidgety, though. Placing the NCV detector (located at the top of the meter) near an operational 120 VAC outlet, the meter would reliably indicate a "Low" AC voltage (green light) when it is near the outlet. However, it takes a lot of tiny meter position adjustments to get the NCV to indicate "High" AC voltage (red light) near the "hot" line of the AC outlet. The NCV operation is unreliable enough that I may just pull out the probes and plug them in. I subtracted a star from the final product rating as a result. I have included pictures of the meter's contents. The red/black meter probes come with a protective cap over the banana jacks - these will probably be lost within the first month of use. The meter probes are normally fully insulated, exposing a small sharp tip for probing circuitry. The same probes also have a removable sleeve (shown for the black probe) that can be pulled off to provide a longer "pin sticker" probe to insert into the back of Molex type connectors for readings. The 2xAAA batteries were already installed into the meter on delivery, with no protective tape to prevent electrical connection to the meter. So, I have followed the recommendations of other reviewers, and have replaced the installed cheap alkaline batteries with new Duracells just in case the original batteries may fail quickly (and possibly leak).
