Get the Best hvac clamp multimeter
The clamp-on multimeter is a favorite for many home DIYers, electricians, and technicians. For such a simple device, there are a number of options to choose from when shopping. Here is a quick breakdown of the key features to look for when choosing the best multimeter for home use.
RV, marine, and industrial multimeters are designed to withstand harsher environments and more extreme conditions. They are built with waterproof housings and are more rugged than standard models. But they are also more expensive, and these extra features aren’t necessary for home use.
Unless you’re a professional, you probably don’t need the highest-amp range available. If you work on cars or other heavy-duty machinery, you may want a multimeter that goes as high as 20 amps. But for most home use, a multimeter with an amp range of at least 1 amp and up to 10 amps will suffice.
Higher-end clamp-on multimeters usually have more features and provide more accurate readings. Some include extra testing leads and probes, along with carrying cases and instruction manuals.
Clamp-on multimeters are rated for maximum voltage, or the highest voltage the multimeter can safely measure. Although this is a safety feature, it can also help you avoid accidentally damaging your multimeter.
Most multimeters have a maximum voltage of 600 volts, which is more than most homeowners will ever need. But if you are working in an industrial environment, you may need a multimeter that can measure up to 5,000 volts. Industrial multimeters also usually have a maximum current range of 50 amps or more.
Clamp-on multimeters come in two ranges: DC (direct current) and AC (alternating current). DC current is the type of current found in batteries, solar panels, and the electrical systems of automobiles. The range for measuring DC current is usually from 0 to 10 amps.
AC current is the type of current used by household power outlets. The range for measuring AC current is usually from 0 to 600 volts. Few homeowners need to measure AC current, so a multimeter with a DC current range of 0 to 600 amps is more than adequate.
The number of ranges a multimeter has is a good indication of its capabilities and overall usefulness. A multimeter with only a few ranges will be less versatile than one with 10 or more ranges.
A basic range is an AC volts range
