Best Clamp on Meter Buying Guide
Can’t make up your mind on what clamp meter to buy? The first thing you need to look at the ranges that are used to measure. This is very easy to use that does not require you to make a direct connection to any live wire and measuring the current flow.
In this buying guide, we are going to list down some of the most important crest factor.
Current
This is the main offer more measurement functions of a voltmeter. However, the way multimeters measure voltage, current, and resistance varies per model. Even so, current measurement is built in all multimeters.
Voltage
The supply voltage is the first thing an electrician checks if an appliance experiences technical problems. Many clamp voltmeters can check AC and DC voltage. AC voltage is emanated from a generated current and distributed, while DC is measured via battery volts.
Resistance
This refers to to the difficulty a current goes through to pass an element. Ohms is the method used for measuring resistance.
Continuity
This determines whether an electrical circuit is closed or open. The majority of multimeters come with a continuity beeper. The device makes a beeping sound if the circuit is closed and halts if the circuit is open.
Crest Factor
This refers to waveform current measurement. This is obtained by checking its peak value against the RMS value. This is important in assessing if a circuit is overloaded.
Other characteristics to Consider
- True RMS current measurement
- Minimum and maximum currents
- AC/DC current or AC only- A DC current continuously flows in one direction and has a fixed magnetic field
- Jaw size needs to be large enough for conductor size and access
- Auto-ranging
- Backlight
- Thumbwheel or dial for choosing functions
- Accuracy
- Clear resolution display to precisely measure the current level of peak value
- Make sure that the clamp meter has the highest of the safety ratings
Types of Clamp Meters
There are two main types of clamp meters available in the market today,
- Current-Transformer Clamp Meter:
- Hall Effect Clamp Meter
There are also many kinds of clamp meters, but they can be broken down into the following categories.
- The basic clamp meters with current measuring capability. These are the simplest versions used by electricians.
- The high performance, pocket-sized clamp meters. These are either AC or DC with a large current range and very accurate measurements. These are made for installers, maintenance teams, and contractors who do work in residential, commercial and industrial projects.
- Clamp meters with large jaws for high current applications. These are usually CAT IV rated and used in utility applications and bus bars.
- Lightweight and money saver multimeters designed for use in hard to reach areas. This is used in cases where ordinary clamp meters can’t handle it.
- Iron vane clamp meter: this clamp meter has a moving iron vane used for measurement. These are true RMS devices used to measure AC and DC current. This is used mainly in industrial facilities.
- Rogowski Coil: this clamp meter has a flexible coil used for measuring AC. A Rogowski Coil is most suitable for use in tight locations such as a building’s phase unit.
- Hall Effect Clamp AC/DC Meter: this clamp meter used to measure DC and AC voltage, and many clamp meters today are designed in this manner.
- Hall effect clamp meters also utilize two ferrite iron clamps
- Current Transformer Clamp Meter: this can only measure AC current
Apart from these, there are also there kinds of multimeters available today. Some are packed with a lot of features that they are more like digital voltmeter in terms of functionality. Others can measure all types of ranges and have a lot of power.
Basic multimeters have limited specificities but also have some digital multimeter function built in. These are also called open jaw meters and are equipped with current forks.
Low-quality multimeters are only capable of AC measurement and don’t always measure to produce a current reading.
More versatile multimeters measure DC and AC current. These clamp meters can do this without needing to interrupt the circuit or break it. Many also have capacitance and temperature measurements included. There are also non-contact voltage multimeters now available.
Clamp meters with closed jaws are also available, and they provide higher resolution and more precise measurements. There are also a wide range of easy to use, compact multimeters with varied current ranges from 600 A to 30 amps.
The biggest benefit of using clamp meters is that they’re compact, simple to operate and fit in tight spaces where ordinary multimeters cannot. Look for clamp meters with good resolutions (10mA is nice) and the ability to measure low and high amps.
You should also look into other specificities like auto range and one hand use so you’ll be at ease when using it.
For instance, there are multimeters capable of measuring as high as category iii to 600A and as low as as 25A. You may have specific needs so take that into consideration as well.
In addition, you should consider the following
Make sure you choose a multimeter that gives you following features.
- For general all purpose current and voltage metering, a regular voltmeter will do fine.
- If you need more specialized multimeters, there are some designed to access hard to reach conductors and wiring.
- The most feature packed clamp meter is not always the best. It really comes down to the features you need.
- Another key factor that you would be considering is the clamp size- The larger the clamp size can you measure the conductor
- Some multimeters do not measure DC current. Read the product description before you buy.
- Power consumption
- Brand: just like with any other product, you should only buy from a trusted, reputable source. Buying from a well known brand also reduces the possibility of you getting a poorly made clamp meter.
True RMS
True RMS is becoming more important because it provides accurate readings that can measure both linear and non-linear loads, regardless of waveforms even if the waveforms are distorted. It is most effective when used for low energy lighting devices. It is also used for power sources that produce harmonics.
If a clamp meter does not have true RMS, it is calibrated for sine waves measurements. Without proper calibration, the results will be prone to errors and render readings up to 50 percent lower.
Given a choice between a true RMS and one that does not have it, always go with true RMS as it is more accurate.
FAQ
Picking the Best Clamp Multimeter for hvac for You
All right now, we have reviewed the top 10 best clamp meters for HVAC technicians. We have gone over the pro, cons, features, and all the essential traits. So now the question is, which of the ten is the best?
To make the decision I used a specific set of criteria including ease of use, qualities, durability, warranty, and how well the clamp meter works in real-life situations. While all the multimeters did good, the Fluke 323 True-RMS Clamp Meter outdid the rest when it came to performance, capabilities, and the criteria I set.
I will not go over the same stuff I already did in my review, but I want to say this high quality clamp is the most accurate I’ve seen in a long time. The response time is also quick so it’s the best budget clamp meter for electricians and hvac technicians who won’t settle for anything less than the best.
The Fluke 323 is also better than the other true RMS meters, combining ease of use with plenty of functionality. You get all the standard components needed in a clamp meter plus a few more. Fluke did an excellent job of implementing these features without ignoring the safety rating.
The bottom line, the Fluke 323 is the best clamp on meter around.
We hope you’ve got enough information from this buying guide, and can make a better purchase decision.
