1. Millivolt Measurement Range

For millivolt measurements, select a multimeter with a wide and precise millivolt measurement range. To be able to measure a variety of voltages, choose a meter that can read from a few millivolts to several volts.

2. Accuracy

When dealing with millivolts, precision is crucial. A high-accuracy multimeter is the best choice. Typically, multimeters display accuracy as a percentage of the reading, so a lower percentage indicates better accuracy. Make sure your meter has an accuracy of at least 0.5%.

3. Resolution

The resolution of a multimeter is the smallest change in voltage it can display. It is crucial to have a higher resolution when measuring millivolts. To capture even the slightest fluctuations, you should have a meter with at least 0.01 mV resolution.

4. Auto-ranging vs. Manual-ranging

 Auto-ranging vs. Manual-ranging multimeter

User-friendly auto-ranging multimeters automatically select the appropriate range for your measurement. A manual-ranging meter requires you to select the range yourself. Beginners may prefer auto-ranging, while professionals may prefer manual-ranging for more control.

5. True RMS

A multimeter with True RMS capability is essential for accurate measurements of non-sinusoidal waveforms. When waveforms are less than ideal, it ensures precise readings, making it indispensable for troubleshooting.

6. Safety Features

Electricity requires a high level of safety. It is important to choose a multimeter with safety features such as overload protection, fuse protection, and a sturdy, shock-resistant casing so that you are protected while using it.

FAQs

Can a multimeter measure millivolts?

A multimeter is a versatile tool that can measure current, resistance and other electrical properties in a device or system. One of the questions people often ask is – can a multimeter measure millivolts? The answer to this question is yes! Multimeters can typically measure up to 200mV of direct current or up to 500V of alternating current. This makes them ideal for low-voltage applications such as industrial control or signal processing circuits.

How do you test millivolts on a meter?

Testing millivolts on a meter is relatively straightforward, though it requires some understanding. First, ensure that you are using the correct meter and settings. For example, most digital multimeters can measure millivolts accurately; but an analog version may be required to measure lower voltage levels. To test millivolts on a meter, you must use the proper probes to connect the device and set the meter to measure mV (millivolts). 

Does Fluke 117 read millivolts?

The Fluke 117 is the perfect tool for precise current measurements, particularly in AC currents ranging from 0.1A to 10A – a range suitable for most household applications!
