Buyers Guide

As mentioned above, buying clamp meters is an investment that you chose to make. Hence, doing so means that you have to be smart with your decisions.

To facilitate that, we’ve compiled a list of things you should keep in mind when going to buy a clamp meter.

Define a Purpose

Defining a purpose or having a plan when buying technical tools is of utmost importance. This is because your end goals will help you specify exactly what type of accessories and features you require in your clamp meter.

Additionally, defining a purpose would enable you to plan a budget which you can adhere to. In that budget, you can choose the best clamp meter that suits your needs well.

Work Environmental Friendly

This suggests that the clamp meter that you’ll be buying works in the conditions where you see yourself using it the most.

This means that if you’re working in hot areas, there should be minimal chances that your clamp meter can’t function in that condition. Vice versa for colder regions and climates.

Additionally, this also extends to indoor and outdoor usages.

Accuracy and Reliability

The accuracy levels of different clamp meters vary. Most of them do have a lower threshold, but it’s best to get one which suits your needs best and gives a reliable reading.

For example, if you’re looking for the best clamp meters for HVAC, you’ll need a tool that is extremely reliable and has a minimal error.


You’ll be dealing in high-risk situations. Remember, a clamp meter is a tool for assistance, and assistance only. Never compromise on your safety.

Since you’ll be dealing with circuitry and high voltages, ensure that your equipment is adequately insulated at the holding points.

Quality Over Quantity, Always

If you’re looking to invest wisely for the long run, it’s best to get a clamp meter that gives the best bang for its buck. Don’t buy a clamp meter with features that you won’t need.

Remember, buy the tool that you require, not what the company wants to sell you.

Frequently Asked Questions

How accurate are clamp meters?

The accuracy in a clamp meter is accounted for as a percentage of the official reading of the device. The accuracy is denoted as an error that might be unaccounted for in the official reading.

For example, an error of 2% would mean that a 100A reading is definitely between 98A and 102A.

The general accuracy levels are below 5%, but it’s optimal to only consider with >3% error.

What is a clamp meter good for?

A clamp meter is used for measuring currents within a circuit without having to disconnect it.

This is done via the usage of hinged jaw mechanism which literally ‘clamps’ the object which is being tested.

A clamp meter is mostly useful for circuit analysis without any external influence on the present circuit.

What is the difference between a multi-meter and a clamp meter?

Both objects are used frequently by electricians yet harbor great differences.

The former compiles the measuring abilities for several different quantities, such as voltage, current, and resistance.

Clamp meters, however, only measure currents and are designed to do with optimal ease and reliability.

What is the true RMS clamp meter?

A true RMS clamp meter is used in the industry for measuring alternating currents.

These currents are characterized by polarized periodic flow, which is why measuring them with standard equipment can get tricky.

To overcome the difficulties, a true RMS clamp meter is used.

What does true RMS meter mean?

A true RMS meter, as mentioned above, measures the magnitude of the alternating current in a circuit. RMS is an abbreviation for Root mean square.

This necessarily implies the equivalent value of the current if it were in a DC (direct current) setting as opposed to AC.

Do I need a true RMS meter?

Concluding whether you need a true RMS meter or not depends on the type of environment and conditions you’ll be working under.

To put things in perspective, it’s best first to clarify your immediate working conditions.

If you feel that you need the additional benefit and will be interacting with AC sources, then a true RMS meter is the right choice for you.

What is a digital clamp meter?

A digital clamp meter has the functions available to all clamp meters.

However, this version accentuates and makes the tool more versatile and safe than its predecessor models.

The digital clamp meter will also help you calculate voltage and resistance, making it into an all-in-one tool that is essential for compatibility.

Can a clamp meter measure voltage?

For the majority of the product on the market, clamp meters work well in measuring currents.

However, some models are built specifically to have this additional feature in it which is why they’re able to measure voltages as well.

Can a clamp meter measure DC?

A clamp meter’s main job is to measure the current going through the wire without causing any obtrusion or having to turn the system off.

Current generally flows in two ways, which is widely termed as direct current (DC) or Alternating current (AC).

Clamp meters can measure DC with relative ease.

How do you use a clamp meter to measure frequency?

Clamp meters can be used to measure frequencies, especially when encountered with AC circuitry.

Generally speaking, all models include a manual that can run the user through the process.

However, the basic crux of it is to turn the knob towards the Hz option and then clamp the jaw shut around the conductor.

What is the clamp on a handheld electric meter used for?

The clamp in a handheld electric meter is used as the medium used for interacting with another surface that can give as quantitative data and information.

This clamp is usually hinged around objects of interest to extract more information about them.

In this case, this implies the current flowing in them, etc.


In the end, it’s your call which clamp meter you want to go with.

Remember, it’s always better to invest smartly and think long-term. Hence, when choosing a clamp meter, make sure you get something that lives up to the expectation you hold for it.
