From testing batteries to determining the amount of voltage in an electrical circuit , the multimeter is a stock diagnostic tool often found inelectricians ’ tool kit . But multimeters also come in handy for DIYers who need totest their home ’s wiringor repair electrical appliances . They ’re also pragmatic for hobbyist — folks who tinker with electronic circuits when build the like of pedometers , motors , and humidness detector .
Prior to the development of today ’s versatile multimeters ( also called multitesters ) , disjoined meters were necessary to screen circuits for voltage ( voltmeter ) , resistance ( ohmmeter ) , and current ( ammeter ) . Now , multimeters combine those testing capability into a single tool , letting youperform a smorgasbord of electric test with one equipment .
A wide variety of multimeters are available , design for both canonical and advanced circuit testing and geared toward different projects or strong point . While a DIYer can usually get by with a no - gimcrackery tool , lineman and HVAC pros will benefit from some of the advanced choice set up on professional models .

We do hands - on testing with some of the best multimeters , so keep reading to see about what we find to aid you choose the right dick for you .
How We Tested the Best Multimeters
Full disclosure : We are not electricians orHVACtechnicians . Our goal was to test these time to the level that the average DIYer would use their meter . Learning how to use these meter to their full capacity and having the serious electrical infrastructure available to test some of those functions is outside the scope of this clause . With that said , we put each of these meters through their paces .
First , we put up a testing station with some retail store , wires , gismo , and a span of shelling . We checked each of the basic functions , like alternate current ( AC ) and direct current ( DC ) voltage , resistance , continuity , and the jaw on the clamp meters . We do work in the darkness as well as the bright sun so we could see how well the displays performed .
We also test these meters in the driveway to see how they ’d do troubleshoot the wiring in an sometime vehicle . We did bare tests like battery lots as well as try out across some less - than - mill wiring jobs . In the cognitive operation , we liken the meters ’ base , leads , and functions as they utilise to self-propelling work .
Between all these tests , we had a good estimation of what the average DIYer can expect from each of these models . Some models did n’t make the grade , while others excel .

What to Consider When Choosing a Multimeter
Choosing the good multimeter requires quite a piece of knowledge about these electric examination prick , including the elan , the feature , the supplement , and the leads . learn on as we break down some of the most of import retainer to keep in mind when shopping for one of these tools .
Basic and Advanced Functions
For the greatest versatility , make indisputable the multimeter can screen both types of electrical current : AC , the electricity that flow through the outlets in the home ; and DC , the electricity found in battery . Additionally , in parliamentary law to qualify as a multimeter , the tool must perform at least two of the next three canonic electrical tests :
In addition to testing voltage , resistivity , and current , advanced digital multimeters often come with the power to try out the following :
Analog Versus Dial Display
The classic parallel multimeter have a telephone dial with a needle ( like the old - clip speed indicator on a car ) . For some , this case of read-out is easier to see , especially in bright sunshine when numbers on a digital show can be difficult to decipher . Shoppers wo n’t get hold a large selection of analog meters anymore , but they ’re typically cheap , ranging from $ 10 to $ 70 , and while they can do the three canonical electric circuit tests , they do n’t have the capability to perform more innovative testing .
Most multimeters on the market today are digital , and they ’re a bit pricier , ranging from $ 20 to $ 500 or even more based on timbre and precision . Some digital multimeters come with a backlit screen that make the display easier to see in brightlight , and some let in an auto shutoff feature that turns the meter off after a few minutes of nonuse .
Auto-Range Function
Figuring out the approximate range of the electric current being test with a manual range multimeter can be a time - consuming process . To essay resistance , for example , you must first estimate the approximative ohms ( Ω ) of the electric current by rick the dial to a specific ohms reach and then go on clicking manually until the multimeter gives a read-out . A multimeter with an auto - range function ( available only on digital models ) will keep open clock time since all you have to do is prize the type of trial to do ( potential difference , ohmic resistance , or current ) . The meter will then automatically detect the right compass by rake through all the grasp pick until it matches the veracious grasp to the circuit , and a readout appear immediately .
Probes and Accessories
Most multimeters admit a set of standard red and bleak probes for performing basic tests , and others come with additional gator clips for seize the probes to wires or battery terminal . A magnetic casing or sling is a handy accessory that appropriate you to attach the multimeters to something metallic element , such as a cabinet or the undercarriage of a car , allow you see the read-out and still have both hand free for testing . These clips , probe , and cases are also available at hardware and home betterment shop .
