It’s then a useful device for testing and diagnosing a wide variety of electrical issues, such as home wirings, circuit board checks and car installations.
But it only has manual ranging function where other budget best multimeters under 50 have auto ranging function, too. As such, it may be unsuitable for use by a complete beginner.
10. Morpilot- Best Mid Range Multimeter
This isn’t an expensive digital multimeter but it does its job well, unless you’re looking for something more sophisticated for industrial applications. It has a large display that gives the relatively correct readings, an intuitive interface common in many budget multimeters and functions for around the house or garage uses. In short, it’s affordable without being an inferior product.
Buyer’s Guide: Answers to Your Questions About the best $50 multimeter
What are some of the common electrical properties that a multimeter can determine?
Modern multimeters can measure numerous values including:
- Voltage for both alternating and direct currents, as expressed in volts
- DC and AC Current bith in amperes
- Resistance in ohms
- Frequency range, such as in microamps and milliamps (Check for the burden voltage)
- Capacitance as expressed in farads (Take note that most general purpose multimeters aren’t designed to measure capacitor status like leakage, dissipation factor and ESR. These are instead typically limited to a few hundred to a few thousand micro farads or, in case of more advanced multimeters, a few pico farads)
- Conductance in siemens
- Inductance in henries
Many multimeters also have extra features but these can add to the price. These features include decibels in circuitry, duty cycle, frequency in hertz, and temperature in Celsius and Fahrenheit.
Many digital multimeters also have continuity tester, which buzzes in case of a low circuit resistance; diodes for the measurement of forward drop; and transistors. There are even battery checkers and other sensors for measuring alkalinity/acidity, relative humidity, sound pressure level, and light level.
How important is design and build quality?
The form, or appearance, of a multimeter is a second concern when choosing the best multimeter. The function is obviously the primary consideration in this regard.
But it cannot also be denied that form can matter as much as function! For one thing, a brightly-colored multimeter will be easier to find when you accidentally misplace it. This is the reason why most multimeters have bright color combinations, such as red and yellow.
For another thing, a quality multimeter should have a large LCD display, an intuitive dial and a user-friendly layout for the buttons and dial. These are part aesthetics, part function but these are the design elements that will grab your attention first.
And then there’s build quality, which should be as top-notch as possible. Multimeters are used in numerous situations, from DIY repairs at home to professional repairs of appliances, circuit boards and HVAC units. For this reason, they have to be strong and sturdy to withstand not just normal wear and tear but the occasional drops on the floor.
The bottom line: Check that the multimeter has your desired measurement functions as well as an attractive, user-friendly and intuitive control panel. The combination of good form and function means better value for your money.
What is a true RMS multimeter?
RMS stands for root mean square and in an RMS device, such as a multimeter, it’s used in measuring alternating current and voltage. Take note that there are three types of measuring devices – a true RMS multimeter; an average responding multimeter; and oscilloscope.
The multimeters are more commonly used than the oscilloscope as these can make accurate measurements of standard sinusoidal waveforms. Between these two types of multimeters, it is preferred because it can make accurate measurements of both sinusoidal and non-sinusoidal AC waveforms.
As such, these multimeters are useful in testing electronic ballasts, computers, HVAC, variable speed motor drives, and solid-state environments.
Do all multimeters test continuity?
No, not all multimeters are designed for continuity testing. Most, nonetheless, should have it.
Continuity testing refers to the checking of resistance between two points. It’s easy enough to know whether there’s continuity – a tone is made in case of continuity. No tone, no continuity, in other words.
In case of ultra-low resistance between the two points, usually less than a few ohms, then the points are electrically connected. If more than a few ohms are displayed on the screen, then there’s an open circuit between the two points.
The continuity test is useful determining the correct connections between two points. It’s also useful in checking of there’s an electrical connection between two points that shouldn’t be there in the first place. For this reason, it’s among the most important functions for professionals doing diagnostic and repair work.
When doing a continuity test, set the multimeter to the correct mode – continuity, of course. Look for the symbol that looks like sound waves being emitted by a speaker or the diode symbol surrounded by propagation waves.
What safety features should I look out for?
While the safety features on digital multimeters vary, the standard safety features that you should be looking for are:
- Inbuilt fuse as protection from disturbances in the power line
- Terminal shutters for preventing incorrect test leads insertion into the current measurement terminals
- High energy fuse for preventing electrical arcs
- Auto discharge capacitors for protecting the multimeter against damage
- Overcurrent protection
Of course, the best safety feature is your knowledge and skill in the safe use of digital multimeters. Always be conscious about the fact that you’re dealing with a powerful natural force – electricity – that can cause serious injuries, even death, when handled incorrectly.
