When choosing a multimeter for electrical work, it is important to consider measurement capabilities (e.g. voltage, current, resistance), auto-ranging or manual ranging functionality, input impedance, safety features (such as fuses), and brand reputation. A reliable multimeter should have a wide range of measurement capabilities, as well as safety features – such as automatic shut-off and overload protection.
Types of Multimeters (and the Difference between MMS & Clamp Meters)
Multimeters come in two main types: Analog Multimeters and Digital Multimeters.
Before I walk you through their main differences, let me clarify the key difference between MMS and Clamp Meters.
As multimeters measure electrical properties such as voltage, current and resistance (and sometimes capacitance and frequency), they require direct contact with the circuit. The key difference here is that Clamp Meters measure current without direct contact. You’d use a clamp meter mainly when you want to measure current without breaking the circuit – making it safer to measure high currents when compared to a multimeter.
So overall, which one would you use and for what?
If you need to measure voltage, resistance, and general circuit diagnostics, a multimeter is the better choice. Otherwise, when measuring current quickly and safely without disconnecting wires, a clamp meter is the way to go.
In this guide, I’m focusing on Multimeters and NOT on Clamp Meters! I’ll have another article on that coming out soon.
Analog Multimeters
Analog multimeters measure voltage, current, and resistance by using a needle that moves across a scale.
The needle is deflected by an internal coil that responds to the magnetic field created by the voltage or current being measured. This is similar to how a compass needle points north due to the Earth’s magnetic field. In an analog multimeter, however, the magnetic field created by the voltage or current being measured causes the needle to deflect in proportion to its strength.
Digital Multimeters
DMMs are currently the most widely used type of multimeter on the market. They provide accurate measurements with fast readings – combining digital and logic technology to measure and verify several electrical properties.
Both these types of multimeters have their own pros and cons, and depending on your needs, one type of multimeter may be more appropriate for you than the other.
Let’s first move on to analog multimeters and explore their pros and cons in more detail.
Pros & Cons of Analog Multimeters for Electricians
Suppose you’re working in a dimly lit work area where it’s hard to see the readings on a digital display. In such cases, an analog multimeter may be easier to read. Analog multimeters are generally less expensive than digital multimeters, and they don’t require batteries or external power sources to operate. They also tend to be more durable since they lack delicate electronic components such as integrated circuits (ICs) that can get damaged over time.
Analog multimeters measure AC voltage and DC voltage equally well but are less precise than digital multimeters. They typically have measurement resolutions of only one-tenth or one-hundredth of the range they’re measuring, which makes them unsuitable for precision work.
Their accuracy is influenced by temperature changes as well as external vibrations that can cause the needle to vibrate. Analog multimeters are also limited in their measurement range, generally up to 500V.
If you find yourself working in a relatively stable environment and don’t require precise readings, an analog multimeter might be a good choice for you. However, if you need precise readings or to measure very low or very high voltages, currents, or resistances, use a digital multimeter.
Now let’s explore their pros and cons in more detail.
Pros & Cons of Digital Multimeters for Electricians
One of the main advantages of DMMs is their ability to measure a variety of electrical properties, including current, voltage, and resistance. With auto-ranging capabilities, they can automatically select the appropriate range of values needed for a particular measurement, making their use much easier and more efficient than analog multimeters.
DMMs also offer greater accuracy than analog models due to their reliable digital displays. They are often designed with user-friendly interfaces and features such as backlit screens, hold buttons for capturing readings, and low battery indicators to help ensure that you always have an accurate reading.
One popular option among professionals is the Fluke 87V Industrial Multimeter, known for its superior durability and advanced diagnostics features. This model has been tested to survive falls up to four times greater than traditional designs thanks to added shock protection. It also includes advanced diagnostics features such as variable frequency drive (VFD) mode to test motors.
DMMs generally come in both manual- and auto-ranging versions. Auto-ranging models are recommended since they make it easier to switch between different ranges without having to manually set the multimeter. The Extech EX330 Autoranging Mini Multimeter is another popular choice for electronics projects and allows you to switch between ranges depending on your specific needs.
Another key advantage of DMMs is their ability to measure both AC voltage and DC voltage, as well as millivolts up to approximately 1000V with great precision.
For electrical work, DMMs can measure from about 200Ω up to a minimum of 20MΩ, and higher if possible for resistance. They can also measure in both the microAmp (µA) range as well as the milliAmp (mA) and Amp (A) ranges for both AC and DC currents.
Features to Consider in a Multimeter
There are several features to consider when selecting the best multimeter for electricians to carry out your work.
The first thing to consider is the safety features. These will prevent damage from overloading, prolong the life of the device, and, above all, ensure that the multimeter is safe for the user. I discuss this in detail below.
Next, be sure to consider a multimeter’s measurement capabilities. As we have discussed, DMMs provide a wider range of options when it comes to measuring various electrical properties – such as current, voltage, and resistance. The best multimeters for electricians will be able to measure these properties with precision.
One model that stands out thanks to its advanced features is the Fluke 117 Electricians True RMS Multimeter. It includes a non-contact voltage detector that allows you to detect live wires without touching them. Additionally, this multimeter provides a low input impedance of up to 600 volt for voltage checking of precise readings.
Safety & Measurement Capabilities of the Best Professional Multimeters
Fuses
One crucial safety feature is the inclusion of fuses in the high amperage range. This prevents potential hazards by cutting off current when excessive levels are detected. The placement of this feature is important as well. Ideally, it should be located in the multimeter itself – so it can immediately respond to a fault instead of taking time for an external fuse to operate.
Voltage Spikes
Another important consideration is how the multimeter handles voltage spikes. Some models may have built-in surge protection or other features to keep users safe from any electrical surges during testing. Additionally, some models are rated for use in hazardous environments, including those with explosive gases or dust.
Measuring ohms accurately
Finally, it’s also worth considering the measurement capabilities of different multimeters. A good multimeter should have a wide range of measurement capabilities for various voltages and currents, as well as the ability to measure ohms accurately. To prevent damage to high-resistance components, input impedance should be at least 10MΩ.
For instance, imagine needing to test an unfamiliar power source that you suspect may exceed 1000V. With a multimeter that only goes up to 600V, you might risk damaging the multimeter and yourself if you tried to measure this voltage directly. However, with a model capable of measuring up to 2000V, you could confidently take this measurement while staying within your equipment’s safe operating range.
Ensure It Conforms with Regulations
It’s also worth checking that your chosen multimeter conforms with regulations like IEC61010-1 (safety requirement standards). For instance, meters that meet these standards will typically have a CAT rating indicating which kind of environment they’re suitable for (Category I is for low-energy circuits like electronics, while Category IV is for high-voltage equipment such as utility company transformers). Choosing a model that meets these standards helps ensure a safer testing experience.
Auto-Ranging…or Not
One potential area of debate when it comes to multimeter safety is the use of auto-ranging features. Although these are generally seen as convenient, some experts argue that they can be more error-prone or even dangerous in certain situations.
For example, if you’re working on a project with both DC and AC voltages present, an auto-ranging meter might not differentiate between them properly and could give false readings. Similarly, in some cases, manual range selection may be more appropriate. For instance, when dealing with small voltages, manually adjusting the range can help avoid fluctuating readings caused by ambient interference.
Auto-Ranging vs. Manual Ranging Electrical Testers
Auto-Ranging
This type of digital multimeters (DMMs) automatically select the correct range of measurement based on the input signal. This feature is ideal for electricians who frequently switch between measurements (e.g., testing various circuit voltages or resistances).
Advantages
- Convenience: Saves time by eliminating the need to manually adjust the range.
- Ease of Use: Reduces the chance of errors for less experienced electricians.
- Flexibility: Ideal for tasks like diagnosing home electrical systems or troubleshooting inconsistent circuit behavior.
When to Use
- When working on circuits with unknown values, such as checking a faulty appliance or outlet.
- During tasks requiring quick measurements without needing precision adjustments.
Manual Ranging
Manual-ranging multimeters require the user to set the range for a specific measurement. While this may seem less convenient, it provides greater control and precision, especially when working with known values.
Advantages of Manual Ranging
- Precision: Helps lock in a specific range, reducing fluctuations and providing a stable reading.
- Specific Use Cases: Better for measuring small values (e.g., millivolts or microamps) where auto-ranging might misinterpret ambient interference.
- Fewer Errors: Prevents the multimeter from switching ranges unintentionally, which can happen with auto-ranging models.
When to Use Manual Ranging
- Measuring small signals in sensitive circuits, such as electronics repair or testing low-voltage control systems.
- When troubleshooting high-voltage or high-resistance circuits where a specific range is known and stable readings are critical.
- In industrial environments with high electromagnetic interference, where auto-ranging might produce inconsistent results.
Example Scenarios
Manual Ranging: Measuring microvolt signals in control panels or troubleshooting precision equipment like motor control circuits.
Auto-Ranging: Testing an outlet for general functionality or checking continuity in household wiring.
