How To Buy The Best Multimeter For Electricians?

You should keep an eye on the following factors while shopping for the best multimeter for electricians:

Digital Multimeter 

Even though all the multimeters we have mentioned have digital displays, you can also find many analog counterparts in the market. Digital multimeters are more accurate, resourceful, and easy to use than analog multimeters. So, it should not come as much of a surprise that a digital multimeter is unambiguously superior to an analog one.

Current

The range of current a multimeter is compatible with, is a very important factor to take into consideration. Some multimeters have a modest range, which might not be suitable for more heavy-duty projects. Pick a current range that you feel reflects your need the best. Otherwise, you would be regretting your purchase decision.

Auto Ranging

Using a meter without auto-ranging means, you would need to be extra cautious while using your meter. To manually find the ideal range, you would have to begin your trials at the maximum range. Then, you would have to work your way down as long as you don’t reach the ideal point. Auto-ranging gives you the chance to skip this step altogether.

Additional Features

Current, voltage, and resistance: these are the primary measurements offered by any multimeter. If you have the budget, you should look for some extra features like testing frequencies, and diodes. Some multimeters also come with a thermocouple, so that you can use those to measure temperature.

AC/DC

Some multimeters strictly correspond to AC, while more advanced models allow for AC/DC interchangeability. Of course, being more AC and DC compatible will make the meter more expensive. If you mostly work on home-based projects, then you might not find many uses for DC. But, for working on automobiles, DC mode is a must.

Display

LCD display

Have a look at the display as well, when you are buying a multimeter for electricians. It might not seem to bear much significance at first, but the truth is, the display size of a multimeter is a crucial factor to take note of. If it’s smaller than ideal, you would have a hard time understanding the readings. You can also choose display backlight for better visibility.

DC Voltage

You need to have a DC compatible multimeter to measure DC voltages with your multimeter. If you need to work frequently on batteries, this is a must-have multimeter functionality for you. Found some batteries lying around? Wondering whether or not your car battery is gone for good? Your multimeter needs to have DC compatibility to be useful in these scenarios.

Capacitance

Measuring capacitance is one of the common challenges an electrician faces in his/her profession. But, not all multimeters are equipped to deal with it. Capacitance is the amount of electrical charge stored in a capacitor. Capacitors are prevalent in electronics, so a multimeter without capacitance measuring ability could be limiting.

AC/DC Voltage

As we have detailed earlier, the ability to switch between AC and DC could be very useful to an electrician. This is not only true for measuring current, you can also find yourself in a similar situation while measuring voltage. If you see this happening, then buy a multimeter that can measure both AC and DC voltage.

Non-Contact Voltage Detection

A non-contact voltage indicator is a neat piece of equipment that every electrician should have in his/her toolbox. It is a tool that can detect the existence of electricity in a wire via induction. The no-touch principle of these devices makes them the safest way to check for voltage. Therefore, it would be a useful feature to have in your multimeter.

True RMS Digital Multimeter

RMS stands for Root Mean Square. A true RMS multimeter can measure AC voltage accurately. But, what makes it better than an average responding digital multimeter? Average responding multimeters can also measure AC voltage, but only when it comes in the form of sinusoidal waves. RMS can do so for both sinusoidal and non-sinusoidal AC voltage waves.

Safety Rating

Check for appropriate security ratings before buying a multimeter. CAT I and CAT III rated multimeters are only good for small circuits and home appliances. For distribution circuits, you would have to buy a CAT III cleared multimeter. CAT IV multimeters are more sophisticated and made for working on primary power sources.

Frequently Asked Questions

Can I Get Shocked Using A Multimeter? 

Yes, it is possible to sustain electrical shocks while using a multimeter. Without proper maintenance, the lead and meter might cause shock. You could also get shocked if you use the meter to measure voltage beyond its capacity. Refrain from using old, faulty multimeters and know about the voltage and safety ratings before picking up a multimeter.

What Is The Easiest Multimeter To Use?

The Fluke 323 is the most user-friendly multimeter we have come across while researching for this article. It has simplistic features, which makes it a great beginner’s model.

Which Is Better-Clamp Meter Or Multimeter?

Clamp meters have a clamp, as the name implies, which you can put on the wire to avoid direct contact with it and determine the voltage. This makes it particularly suitable for dealing with heavy-duty projects. Conventional multimeters, on the other hand, offer more preciseness, but they are not as safe as clamp models.

So, the choice comes down to personal preference. If you want more security and need to work with higher voltages regularly, then a clamp model would be fine for you. But, if you work with moderate voltage and prioritize accuracy over safety-then a multimeter would be a sensible pick. Most professionals carry both of these with themselves.

What Is A Good Cheap Multimeter?

The Ideal 61-746 is a very good multimeter to select if you are extremely tight on the budget. It has auto-ranging, TMRS, and even a built-in non-contact voltage indicator. The LCD display is excellent too. Overall, it is a very enticing package for anyone who is in the market for a meter that goes very easy on the pocket.

What Should You Not Do While Using A Multimeter? 

Never take voltage readings when your test probes are still attached to the current terminals. It would shock you, but the fuse should offer some sort of protection. However, the fuse is not a 100% effective safeguard measure.

How Do You Check If A Multimeter Is Working?

Measure a known value to see if your multimeter gives out the same reading. For instance, take a 9V battery and take its reading. If the multimeter does not read 9V, then it is flawed. You can switch between multiple batteries, to confirm that it is the multimeter that is faulty, not the battery.

How Do You Check 240V With A Multimeter?

A 240V wall socket has two power slots and an earthing slot. The power slots carry 120V each, while the other one only connects to the ground. Set your multimeter range to 240 volts, insert leads, and then attach them to the outlet power slots. The reading should show 240V, if not, the circuits or, one of the circuits is/are malfunctioning.

Which Is The BEST Clamp Amp For HVAC?

Klein Tools CL800 is the most appropriate clamp meter to choose for HVAC (Heating, Ventilation, and Air Conditioning). It is not oversized, so the clamp can go into tricky places. The reverse contrast LCD display makes the display readings perceivable despite low lights, which is also a plus side or HVAC application.
