5. Buying Guides
Are you not knowledgeable about electricity but still want to own a device to help check the current in your home? No need to understand too much about complicated parameters. Refer to the instructions below, and you will find the best clamp meter for HVAC.
Types
Based on the type of currency you want to measure: The AC DC, there are two most basic options:
AC Clamp Meter: This device can only measure alternating current. The principle of operation of the device is based on the electromagnetic induction of a secondary current.
DC Clamp Meter: If you work with electronic circuits, AC Meter will not meet your needs. Instead, you need to choose a DC Clamp Meter to measure DC.
If you want a device that can measure both AC DC currents, the Hall Effect Meter will be the better choice.
Safety
All activities related to electricity have potential risks of electrical failure. Therefore, it would be a mistake to disregard the safety factor when choosing a clamp meter.
If you are not knowledgeable about insulation materials or insulation design, consult the numbers related to safety ratings. Generally, the higher the metric regarding the product’s resistance, the greater the electrical safety.
Or you can also use CAT electrical safety ratings for multimeters to assess product safety. Best advice for you: choose a product with electrical safety certification between two devices with the same parameters.
Clamp Size
The clamp of a device that functions as a support to help hold the conductors. You can also use the clamp to test the circuit safely.
The clamping part of the meter is usually between 17mm and 45mm in size. Depending on the purpose of use as well as the use environment, you have your own choice.
Some best clamp meters also can adjust the size.
Accuracy
The main function of the meter is measurement. And it’s useless if the device can’t give accurate results.
In terms of the accuracy of a clamp meter, you need to pay attention to the smallest error. Today, most devices have an error of less than 5% for conventional measurements and less than 3% for voltage measurements.
You can determine the accuracy of the device by measuring a parameter yourself on the same constant current. A high-accuracy meter will give results that are consistent or at least not too misleading.
In addition, the accuracy of a meter can also be assessed by the time it takes to update the results. A device capable of updating results 3 times per second will certainly give the most current results compared to a device with less update frequency.
However, you should not worry too much about the accuracy of the device. Choosing the best clamp meters from big brands will solve your obsession with too many different results after each measurement.
Maximum Resistance Limit
Simply put, resistance is a measure of how well it prevents current from flowing through a conductor.
Normally, the Maximum Resistance Limit of the current digital multimeter is 4kΩ. In particular, there are products with a Maximum Resistance Limit of 10kΩ.
Not that the Higher the Maximum Resistance Limit, the better the clamp meter. The maximum Resistance Limit should depend on the type of currency you need to test.
If you are an electrician and your job is to test large electrical equipment, owning a meter with a Maximum Resistance Limit of up to 10kΩ is natural.
However, if you’re only testing residential current in your own home, there’s no reason why you should pay extra for a high-resistance meter.
Backlit Screen
The screen is where the measurement results are displayed. And it will be annoying when you can’t see the measurement results clearly because of the poor screen quality. Many manufacturers have equipped their devices with clear LCD screens, capable of displaying up to 3,999 characters.
However, the above improvements are probably not as necessary as the screen’s backlight.
There is a problem with the current lighting system does not work. And to check the current, you may have to use a clamp meter in low light.
Or conversely, if you are an electrician and do regular electrical repairs outside, the strong light from the sun can make it difficult to read the results.
A screen with a backlight will be very useful in the above cases. The backlight will not affect the power of the device too much. Therefore, do not miss this great feature.
Crest Factor
Crest Factor helps you to evaluate the waveform, check the overload of the circuit.
The Crest Factor is calculated by subtracting the base mean square (RMS) from the peak value.
If you choose to buy a product that features a direct display of Crest Factor, you will save a lot of time on calculations.
Smart Phone compatibility
Best clamp meters 2021- the age of technology, innovation- it is impossible not to have the ability to connect to smartphones.
Firstly, you can see the results through the phone screen instead of standing near the power source. This will make it safer for you to accurate measurements.
Second, with mobile applications, you can adjust the meter remotely, experiencing many conveniences.
And finally, you can receive notifications, alerts via mail and store the data each time with cloud storage.
Because of the above benefits, you should prefer a digital multimeter that can connect to smartphones via Bluetooth or IR.
Additional Accessories
Additional features will make your experience more perfect.
Some additional features you should consider such as work lights to illuminate in low light conditions. Or the cover helps prevent dust as well as preserves the tool well. Or an accompanying box will also be the competitive point of the product when compared to other products.
Design
Design is also an issue that cannot be taken lightly when choosing a clamp meter.
You should consider the design of a meter in the following order:
First, pay attention to the size and portability of the product.
A meter is a hand tool, so a compact, easy-to-handle design is the first requirement. Besides, you will probably take the clamp meter anywhere. So make sure the device fits your tool kit.
Second, you should pay attention to the screen design. The size of the screen should be large enough. And as mentioned, a good LCD with backlighting is a priority.
Third, you need to pay attention to the control buttons. Whether you can easily use a meter or not depends greatly on the sensitivity of the buttons.
And finally, since the impact is inevitable because digital multimeter is a tool used in labor, consider the product’s durability.
Measurement Parameters
A meter must, of course, be able to measure alternating current.
But in addition to measuring AC, many devices also integrate the ability to measure the AC DC voltage and many other parameters.
Some of the measurement parameters you should have in a meter are resistance, capacitance, and diode.
The more parameters you have, the more precise you can get the state of the current.
Warranty
Warranty will help protect your rights. Some brands will have a one-year warranty against non-manufacturer defects. Some of the more quality brands offer three-year contracts.
Of course, the products of the big brands will be more expensive than the products with no name. But in terms of time to use and your benefits, you will have your own choice.

Electricians are people who often use multimeters. If you simply want to measure the speed of the current, a meter will surely satisfy you.
What are the safety precautions when using a clamp meter?
A device with electrical safety certifications can only give you peace of mind, but it can’t distract you from electrical exposure. To ensure safety when using a clamp meter, follow the guidelines below:
- Check the tool, especially the insulation around the connector. If cracks are found on the device, discontinue use.
- Do not use a meter without a fully assembled back cover and housing.
- Use only batteries that are compatible with the device. Install the battery properly. Replace the battery as soon as there is a low battery warning.
- If the probe is damaged, replace it before using the device.
- Use caution when removing and mounting the probe.
- Do not use the device in an explosive or humid environment.
- Observe electrical safety rules.
Can you measure the voltage with a clamp meter?
Of course, you can measure voltage with a clamp meter. The steps to measure voltage are as follows:
- On the screen, there will be two options AC Volt and DC Volt. Choose one of the two.
- Adjust the probe section so that the black end is in the COM jack.
- Similarly, plug the red probe into the V jack.
- Power the circuit to start measuring.
- Get the results displayed on the screen.
- When reading the results, depending on the device type, you have the option of Hold to compare data or check the maximum and minimum value.
- It should be noted that when you perform voltage measurements, the signal frequency may affect the final result. Some clamp meters typically have a frequency range of 500 Hz. Meanwhile, some multimeters have a frequency range of up to 100 kHz.
- Therefore, two instruments with the same current can give different results.
How do you measure power using a clamp meter?
- Step 1: Check before measuring: make sure to disconnect the probe. Check the device once, stop using it if there are abnormal signs.
- Step 2, select AC or DC measurement function depending on the purpose.
- Step 3: Close the jaw.
- Step 4: Select Zero to remove the offset.
- Step 5: Release the jaw, put the wire inside the jaw.
- Step 6: Close the function. Align the jaws to align the conductor to the center position.
- Step 7: Read the result.
