If you’re in the market for a new electrical meter, you may be wondering what the difference is between a multimeter and a clamp meter. Both of these meters are used to measure electrical current, but they have different applications. In this blog post, we will discuss the differences between multimeters and clamp meters, and help you decide which type of meter is best for your needs.
What Is A Multimeter
Analog Multimeter
Analog multimeters use a needle and calibrated scale to display readings, while digital multimeters show readings on a numeric display. Both types of meters have their own advantages and disadvantages, but digital multimeters tend to be more popular due to their ease of use and higher accuracy.
Digital Multimeter
Multimeters often have various settings and functions to specifically measure AC or DC voltages, as well as the ability to test for insulation resistance and transistor gain.
What Is A Clamp Meter?
This allows for safer measurement in situations where disconnecting the circuit or breaking the wire’s insulation may not be possible.
Clamp meters are typically designed only to measure current, although some models may also include features such as voltage measurement or non-contact voltage detection.
Difference Between Multimeter And Clamp Meter
Design
The main difference between a multimeter and a clamp meter is in their design. A multimeter is typically a handheld device with various probes and ports for measuring different types of electrical values, such as voltage, current, and resistance. Meanwhile, a clamp meter has a clamp-like jaw that allows it to measure the current flowing through a wire without the need for direct contact.
Functionality
While both devices can be used to measure current, a multimeter can also measure voltage, resistance, and other properties. A clamp meter, on the other hand, is limited to just measuring current. Additionally, some advanced models of clamp meters may also have the capability to measure voltage and resistance.
In certain situations, a clamp meter may be the more practical and efficient choice. For example, when measuring current in an enclosed wire or tight space, using a clamp meter eliminates the need to break the circuit and potentially disrupt the flow of electricity. On the other hand, a multimeter may be better suited for measuring multiple properties in one go or for more precise measurements.
Accuracy
In terms of accuracy, a clamp meter is typically more precise when measuring current, as it does not require breaking the circuit for measurement. However, a multimeter can still give accurate readings if used properly.
Need Of Breaking The Circuit
The fundamental difference between a multimeter and a clamp meter is that a multimeter measures the voltage, current, and resistance in a circuit by breaking it, while a clamp meter measures the same values without breaking the circuit. This makes clamp meters particularly useful for measuring live wires or in situations where interrupting the circuit could cause damage or danger.
Measurement Range Differences
Clamp meters also typically have a larger measurement range than multimeters. While most multimeters can measure up to 10 amps, clamp meters can often measure up to 1000 amps. Additionally, some clamp meters are able to measure other properties such as capacitor value, frequency, and temperature.
Safety
In addition to allowing for measurement in live circuits, clamp meters also have the added benefit of being safer to use. Since they do not require breaking the circuit, there is less risk of electric shock for the user.
Best Suited For Different Applications
Both multimeters and clamp meters have their own unique advantages, making them suitable for different applications. Multimeters are more versatile and can be used in a wider variety of situations. However, clamp meters are essential for measuring high currents in live wires and offer added safety benefits. Ultimately, it is important to consider the specific needs of your application before deciding which tool to use.
Cost
In general, clamp meters tend to be more expensive than multimeters. This is due to their specialized design and added features. However, for certain industries or situations where measuring live wires is necessary, the added cost may be worth the benefit of being able to safely and efficiently measure high currents.
Whether a multimeter or clamp meter is the better tool for a particular job comes down to the specific needs and circumstances of the task at hand. Consider all factors such as safety, measurement range, and cost before making a decision on which tool will best serve your purposes.
Overall, both multimeters and clamp meters have their own advantages and disadvantages, and it ultimately depends on the specific task at hand in determining which device to use. It may also be useful to have both tools in your toolbox for maximum versatility.

It does this by clamping onto the wire with its jaws and taking the measurement.
On the other hand, a regular multimeter can also measure current by directly touching or cutting into the wire with its probes. However, this may be dangerous and not always feasible in certain situations.
In terms of testing a battery with either instrument, both a clamp meter and a multimeter can be used to measure the electrical current flowing through it. However, a clamp meter would generally be preferred as it allows for easier and safer access to measure the current without having to disconnect or cut into the wires.
How do you measure DC amps with a multimeter?
To measure DC amps with a multimeter, you would set the multimeter to the “DC Amps” setting and then place the red probe on the positive terminal and the black probe on the negative terminal of the circuit. The reading on the display will indicate the current flowing through the circuit in amps.
How many amps can a multimeter handle?
A multimeter can typically only handle small amounts of current, usually up to 10 amps. On the other hand, a clamp meter is specifically designed for measuring larger currents and can handle up to 600 amps or more.
How do they measure current?
While both devices measure current, they do so in different ways. A multimeter measures current by placing its probes directly onto the circuit, while a clamp meter measures it by clamping around a wire or cable without interrupting the flow of electricity.
What do you use to measure current?
Typically, a clamp meter is used to measure current. This instrument uses a clamp-like device to directly measure the current flowing through a wire.
On the other hand, a multimeter can also measure current, but it requires the wires to be disconnected and the probes placed directly onto the circuit.
Additionally, a multimeter can also measure voltage, resistance, and often other values such as temperature and capacitance. A clamp meter typically only measures current.
How does a clamp meter measure leakage current?
A clamp meter measures leakage current by placing its clamp around a wire or cable to measure the current flowing through it without having to make contact with the actual wire. This allows for more accurate and non-invasive measurement of current. Alternatively, a multimeter measures current by being directly connected to the wire with its probes.
How do you measure a 3-phase current with a clamp meter?
With a clamp meter, you would place the clamp around one of the conductors in the circuit. The meter will then measure the current flowing through that specific conductor. To measure the total 3-phase current, you would need to repeat this process for each conductor and add up the individual readings.
On the other hand, a multimeter can directly measure the total 3-phase current by connecting its probes to all three conductors simultaneously.
Another key difference is that a clamp meter measures only AC or alternating current, while a multimeter can measure both AC and DC (direct current) electric currents. Additionally, multimeters often have more advanced features such as resistance and voltage measurement capabilities.
How do you measure current on a 240v circuit?
One option is to use a clamp meter, also known as a current clamp or amp probe. This tool measures current by clamping onto the wire, allowing for hands-free measurements without breaking the circuit.
Alternatively, a multimeter can also measure current by placing the probes directly onto the wire. However, this requires breaking the circuit and can be more time-consuming and potentially dangerous.
Can a clamp meter measure Watts?
