Whether you are a household handyman or a professional electrician, a multimeter is a crucial part of your toolkit. A multimeter enables you to measure resistance, current, and voltage. There’s no other tool that can troubleshoot wiring problems as great as a multimeter.
Multimeters have different types. For instance, split fork multimeters can fit into tighter areas that are very practical when cables are run close together. On the other hand, a clamp or hook-style multimeter makes hands-free operations simpler. That’s why multimeters are essential when you’re doing any kind of electrical task.
What is an AstroAI Digital Multimeter?
One of the reasonable full-size digital multimeters on the market today is AstroAI Digital. It’s a true RMS multimeter with auto ranging and RMS-ranging capability. A basic test device for most DIYers, it’s simpler to use and can measure continuity, resistance, voltage, temperature, frequency, and current. Others might compare it to a Fluke on specific aspects, but it does not compete at that level.
Some of its features include:
- Weight: at least 12 ounce
- Size: 7.5 inches x 5.6 inches x 1.2 inches
- Powered by a 9-volt battery
- Has low battery indicator
- Diode test
- Big, backlit screen
- Data hold
- Manual and auto ranging
- Continuity beeper
What is included in the unit?
- 9-volt battery
- User manual
- Multifunction socket
- Temperature probe
- Test leads
Digital multimeters like this one are composed of an LCD screen, a knob to pick different ranges, an analog to digital converter, as well as an internal circuit for signal conditioning.
Just like any other device you buy, safety is a major aspect you should never ignore when you buy a DMM. If you know that you will be working around high voltages, identifying which multimeter to use is extremely important.
Upon selecting a multimeter, make sure you consider the amount of current that will be flowing through the conductor. You may even consider obtaining a cross between a multimeter and a clamp multimeter.
What’s the Good Thing about AstroAI Multimeters?
Did you know that this particular multimeter has been remarketed in the West from the Kuman WH5000A? A run-of-the-mill DMM around the 30-dollar to 40-dollar mark. It also looks the part and measures most things, if a little twitchy and cluttered.
DC and AC voltage is on numerous scales and can be measured in either manual or auto ranging models. You will also find amperage scales even though the former is just suitable for short bursts at greater energies. Together with resistance and the continuity with the beeper, you can test for frequency, capacitance, and temperature.
It’s worth mentioning as well that you do tests on the transistor through a multifunction test. The transistor checker puts out low voltage and is CBE configuration. Nonetheless, it will help if you seek other devices with better specifications, especially if you like to have that function.
One of the apparent pluses of using the AstroAI DMM is that it comes along with different functions and features. Such involves a big screen with a backlight, a MIN or MAX button, allowing you to easily save low and high readings—a relative mode, data hold, and range button.
Measuring temperature obliges you to plug in a thermocouple and can do so in Celsius or Fahrenheit. That’s not totally banging on accurate or entirely consistent, but it rarely is on cheaper meters.
One of the excellent features of this DMM is the inclusion of the magnet hanger. You would normally have to purchase that item individually, which is often the case with a standard Fluke DMM. On top of that, you will find a tiding or kickstand bale for propping it up on the bench, as well as the ceramic fuses, which are simple to get to.
What’s more, the continuity test features a beeper. Just keep in mind that every position encourages the beep that could get quite annoying at times.
- Excellent Display
The big display is a big plus for this DMM, as it measures approximately 2.5 inches by over 1.5 inches. Further, the backlight will help most in dimly lit spots but just stays on for several seconds with every press and washes out at an angle.
Remember that the display count is 5999, along with auto range and sample rate a bit slow.
- Safety and Functions
Screen features involve polarity indicator and battery warning. You won’t find an auto power-off function to save the battery. Nonetheless, that can’t be disabled.
Moreover, the fuses are one of those ceramic types to better safeguard the unit, and you must have one lest there be a surge. These are 10A for the higher range and a 400mA for the low amperage scales. Those are easily accessed from the rear.
- Build Quality
The AstroAI DMM was designed to look a bit like some of the best-rated, branded multimeters. The reality is the quality is a bit cheap, using fewer durable materials and a low-cost overall feel. It has a very stiff position switch, not to mention the probe test leads are very much on the average side.
To sum up, AstroAI digital multimeter for those hobbyists out there. However, it is less suitable for electricians and HAM radio enthusiasts. This multimeter has a decent specification and accuracy and comes with a good backlit screen and practical functions. Nevertheless, it’s a bit quirky and not suggested for high amperage works.
With this multimeter, you receive auto-ranging that suggests you do not need to pick the mode you’re using manually. That makes it very simple for starters to use it. Further, the build quality is much better than other digital multimeters in its price range.
You will receive a very capable multimeter when pricing one. That packs a huge amount of features without costing as much as the top-tier multi-testers without sacrificing build quality.
There you have it! We hope you finally understood how you could start using AstroAI digital multimeters. Do you have any thoughts about this post? Share your thoughts to us by leaving your comments below.
