Are you an electrical professional? Then you know how important a clamp meter can be in your day to day job or activities in order for you to be able to troubleshoot and resolve electrical issues. Or you are a passionate person that enjoy electrical DIY (do it yourself) projects or simply a homeowner. Then you need the importance of a reliable clamp meter that suits your needs.
Either if you are a professional or not, these days you will find really hard choosing a clamp meter that suits you with all these offers available on the market. Any multimeters are able of measuring current, voltage and resistance. Even if these measurements are secured and it will be out of the ordinary to cause you any harm, the current is a big exception, that is why every professional is using a clamp meter. As all current emits magnetic radiations, clamp meters surely profits of this matter as the current is measured based on the magnetic radiations emitted.
With a good clamp meter, you can be accurately determining the amount of current that travels through a cable and you can also check if a circuit is either live or not. Before you go ahead and buy a clamp meter you should do a bit of research and make sure that you will get a good quality product that will satisfy and suits your needs.

Bellow you cand find a list with features that might be worth checking before going ahead with your purchase.
This is the primary offering of a voltmeter with further measuring functions. The manner in which multimeters calculate voltage, current and resistance vary per model, however. Even so, all multimeters are constructed to measure the current.
The first thing an electrician tests if an appliance encounters mechanical difficulties is the supply voltage. AC and DC voltage can be tested by several clamp voltmeters. AC voltage is emitted and distributed from a produced current, while DC is calculated by battery volts.
This refers to the complexity of an entity going through a current. The tool used for resistance calculation is Ohms.
The protection standard it offers is the first and foremost thing that you need to remember in a clamp meter. This can be easily understood when looking at the building material and the device’s build efficiency. The higher the device’s average voltage current and resistance rate, the better it is. Safe systems often come with a wide variety of regulatory certifications and yell for protection with these guarantees.
You do not have to spend a lot of money in order to buy a reliable clamp meter. A lot of companies offers products suitable for all pockets but usually is based on the brand and the included highlights. Higher priced clamp meters tend to be more solid and more precise than the lower-priced ones.
In the laboratory, it is one thing for the clamp meter to work and another to work in the field. The degree of precision you enjoy in the lab can not be preserved in the field. Check if they will work in the setting that you want them to while searching for a clamp meter. For eg. do not purchase one that is listed for indoor usage only or one which has a minimum operating temperature range of 15 Fahrenheit when searching for a meter for outdoor measurements.
A clamp meter can give you true readings of RMS. It puts you in a tough situation when the readings are incorrect and you don’t know if it is the clamp or the motor that is wrong. The meter you purchase is meant to work for you and not against you.
The scale of the clamp corresponds to the machine’s opening ends, which are the real holders you will use to hang on to the conductor. These openings often vary from a mere 17 mm to nearly 45 mm. They are open-ended and can be stretched or expanded so that the conductor blends in and is often hands-free (to ensure that the conductor does not have to be physically touched, In comparison, clamp meters much of the time come with non-contact voltage detectors that can first measure the conduction wire by wrapping the clamp around it.
Are clamp meters accurate?
Yes to some extent. However, to within 1 % of the range, some clamp metres are accurate. Although 1 % error tends to be more accurate than 2 %, 4 amps could be out of a metre that can accommodate 400 amps. The smaller your measurements are with this metre, the lower your error is. There will be a 1 amp reading of 0.98 amps and 1.02 amps.
Clamp meters or multimeters which are better?
In essence, a digital multimeter is a voltage-measuring instrument with some current skill. Basically, a clamp metre is a current-measuring device with certain voltage capabilities. They are distinctly different tools, each with its own benefits. In general, a clamp metre tests to the nearest tenth or hundredth of a unit.
Are clamp meters safe?
Yes, if you properly follow the guidelines you don’t have to worry. Clamp meters are equipped with safety instructions to help users prevent electrical shocks or personal injuries. Always follow the manual requirements and use the meter as defined in the manual only, otherwise, it can compromise the safety given by the meter.
