There used to be stark clamp meter vs multimeter differences, with a clamp primarily built to measure amperage and a multimeter for voltage, resistance and establishing continuity, with less focus on current. Measure electrical systems to a higher resolution.More measurement criteria, such as voltage, capacitance and frequency.Might struggle to open jaws in tightly-packed trunking.Generally lower accuracy and resolution.

Good for dual-purpose measuring, such as a machine speed as well as current drawn.

Ideal for troubleshooting current in-situ.

Lets you measure current without breaking the circuit.

Some also boast wireless connectivity or have a detachable display.īasic multimeter: Can measure voltage, resistance, continuity to varying degrees of accuracy.Īdvanced: More features & functionality (such as Min/Max recording), better reliability, higher accuracy and resolution, faster continuity checks / auto ranging, and safer (higher CAT ratings).

Includes temperature input and a micro-amps rangeīasic clamp meter: Measures higher AC amperage only and is without other measure criteria.Īdvanced: Also has other functions, or perhaps loop/inrush current features.

Good range of features for a cheap multimeter.

As with clamp meters, most are digital nowadays, but are typically available in many more brands. They consist of a dial and display and are either auto- or manual-ranging.

Also measures AC & DC voltage, resistance.

Also measures voltage, resistance, continuity, capacitance, frequency.

You can get past this if you have one that allows for a plug-in accessory, such as many of the Flukes do. They also only usually test to 10A – or up to 20A in short bursts – before fuses start to blow. This is both time-consuming and potentially dangerous.

Multimeters that can test current do so ‘in series’ within the circuit, such that you need to break it to allow current to flow directly through the meter. What They Look Like Clamp MeterĪrchitecturally, clamp meters are just that non-contact test tools that clamp around a cable to determine amperage inductively.

But with many electrical tasks, the former will be fine. With an amp clamp, you might get down to the hundredths of a unit, or tenths, as opposed to thousandths and millionths. If you’re into electronics, having a DMM is a no-brainer, since the higher resolution/accuracy in a good one allows you to see minute changes at the milliohms, millivolts and even micro-amps level. However, an amp clamp multimeter somewhat thwarts this generalization in that they may also come with pretty good accuracy specs on voltage and resistance. The main clamp meter vs multimeter difference is that they can measure high current, while multimeters have higher accuracy and better resolution. Nowadays, some clamps also include the measuring abilities of basic multimeters, and, likewise, some test meters allow for the attachment of an amp clamp (such as the Fluke iflex). A clamp meter is primarily built for measuring current (or amperage), while a multimeter typically measures voltage, resistance, continuity, and sometimes low current.
