What Type of Features Should You Look For in a Multimeter?

If you ever encounter any type of electrical project or have an issue with an electrical component, then a multimeter will help you more than anything else in the world.  Every household and every tinkerer should have a multimeter to help get you out of tricky situations both safely and effectively!

Thankfully with modern day multimeters you don’t have to be an expert or a professional to get many of the uses out of a multimeter.  If you are looking to check AC or DC voltage on an appliance or electrical component, then you don’t have to be a professional electrician, you just need a multimeter.  By being able to check voltages, you will effectively be able to fix and repair any type of electrical appliance in your home!  Look at AccurateElectricity, you’ll find all the functions that you’ll actually use.

So, that being said, what are some of the best features you should look for in a multimeter?

Below we will highlight some extremely important features you should be sure to look for before you purchase!

1. Graphic Function:

Multimeter Graphing FunctionIf you are testing voltages and measurements then you will want to have the most up to date and accurate information possible.  That being said, if you purchase a multimeter with a Graphic Function, this function will show you the voltages of the appliance in real time on a graph on your multimeter.  This will become extremely useful when you are trying to test an appliance that might have a fault in it.  With this function you’ll be able to tell specifically when a stoppage of voltages occurs, which makes it much easier to find a problem area.

2. Data Logging Function:

Another great feature to have on your multimeter is to have a data logger.  If you re working for long periods of times, you’ll want a function that keeps track of all the data as you go along.  This software records the data you’ve collected over a long period as you work, and allows you to look back and analysis it as necessary.  This is an extremely important function if you are working on larger systems like air conditioners or ventilation systems.

3. Low Pass Filter Function:

If you are in need of the ability to troubleshoot and work on motor drives, then you are going to need a low pass filter function.  This is a higher level feature, and not all multimeters will be equipped with it.  But essentially what this function does is filters out and prevents voltages that are unwanted from appearing in your readings.  This gives you a higher level of accuracy when dealing with electronics like motor drives or inverters.

4. Low Impedance Function:

This feature helps to lead to more accuracy when measuring based on preventing induced voltages from being read and recorded in your measurements.  Low Impedance mode helps to block readings that might come from other wires when you are reading a bundle of closely tangled wires.  This prevents low voltages from disrupting your readings and can be incredibly effective to have on tight projects.

5. Smart Ohm Function:

For this function you will definitely need one of the better more advanced multimeters available on the market.  The Smart Ohm function helps to increase accuracy in measurements by detecting any offset voltages in the reading.

6. Voltage Tester Function:

One of the most common features on any modern multimeter is gonna be a voltage test.  The test begins by using the highest voltage test possible and it moves down the voltage range until it finds the most ideal voltage for the appliance you are testing.  This helps when you are testing multiple appliance in quick succession which might be at different voltage ranges.

Final Thoughts on Functions You Need on Your Multimeter

Overall, when you re looking for a multimeter for any projects you might face, it can help if you know which functions you’ll need.  Once you know which functions will be helpful to you and that you’ll need in your everyday life, then from there you can find a multimeter that has all of these functions!

Collection of Multimeter Tips and Tricks #1

Hello Everyone, I have been recently gathering together some tips and tricks for multimeters that I think will be beneficial to you guys!  I found this video online and it really covered some great tips.  I have added the video below for all of you guys to check out!  If you need help looking for some quality electronic testers then look at https://accurateelectricity.com

I hope you enjoy it, remember to always be safe with your multimeter!  These tips will make your job measuring a whole lot easier, and it might even teach you a few functions of a multimeter that you didn’t know you could do!

Tip 1: Top 9 Must-Have Functions For Your Multimeter:

  1. Auto-Off Function: An auto-off function is an extremely simple but also extremely handy.  This function automatically turns off your multimeter when there has been a lack of input by the user for a certain amount of time.  This is extremely handy on a job site so you don’t run out of battery during the middle of your job.
  2. Auto-Ranging:  Auto-ranging helps to eliminate confusion when you are testing two different and separate circuits which might be confusing.
  3. Min/Max/Average Features: This helps to capture the minimum, maximum and average inputs of nearly any current or circuit that you are testing.  Incredibly useful when you are looking for specific data points when testing.
  4. Hold Button:  A hold button is a button you can press that freezes your screen and “holds” the data on your screen for you to look at or record which is incredibly useful.
  5. Frequency & Duty: This records the percentage of time a digital signal is on over a specific period of time.
  6. Bar Graphs and Tables: Multimeters that feature graphs and tables are incredibly useful and allow the multimeter to display data from your tests in an easy to use and easy to read format.
  7. Diode Testing Capabilities: Not all multimeters can test diodes.  If you know you are dealing with diodes and need the ability to test their capabilities, then make sure your tester can accomplish this!
  8. Safety Rating: If you are dealing with high powered currents, then you need to double check your safety rating.  If you are dealing with volts over 1000, then you will need a CAT III rated tester.
  9. True RMS: True RMS testers or Clamp Multimeters is a type of tester that can accurately measure both sinusoidal and non-sinsusodial AC waveforms.  If you need to be able to test these type of AC waveforms, then make sure you have a true RMS tester!

I definitely suggest you take some of these multimeter tips to heart, they will help you save some time and even keep safe!

How To Use a Multimeter!

How to use a multimeter

Here is the layout of the general multimeter.

Multimeters can be incredibly useful and a vital tool to many people.  But they won’t do you any good if you don’t know how to use them!  I have been in the contracting and construction field for nearly my entire working career.  I have used quite a few different types of multimeters and electric testers in general.  Because of this, I have learned the ropes, and I am here to explain how to use a multimeter as easily and as safely as possible!

A multimeter does three simple functions; it measures electric currents called amperes,  it measures resistance measured in ohmmeters, and voltages measures in volts.  Although these all may sound pretty similar, each of these functions have their own specific settings that need to be used to measure accurately.


Before jumping into using your multimeter, you need to be extremely careful.  You are dealing with live electricity and it can be extremely dangerous.  So be sure to make sure to check your multimeters conduct measurements and make sure you don’t exceed these measurements when you are dealing with live currents.


Resistance is measured in Ohms which is represented by the symbol Ω.  Before you try to measure the resistance of any electronic, you will need to disconnect the wiring and power of what you are measuring.  This will keep you safe from any live currents that could otherwise harm you.

From there will you have to change your multimeter settings to the Ohms or Resistance setting.  Generally this is done with a dial, or maybe a button if you don’t have a dial on your multimeter.  From there you will have to take your red lead and connect it to the port symboled VΩ, and the black lead to the common port. Now all you have to do is connect the red and black leads to the circuit you are trying to measure.  From there you should be displayed with your measurements on the screen.


Current can be extremely dangerous when you are measuring it, because you are exposed to an open circuit.  Generally the standard safety rating for a current is at 300mA.

To measure current, you will have to set the multimeter to the ammeter function or current function depending how it is labeled on your multimeter.  Then you will set up the terminal leads similar to how you set them up with measuring resistance.  From there you will attach the lead to the circuit and the other to the open points in the circuit.  You will then be displayed with the results in the form of amps.

The great thing about multimeters is there functionality.  They are really combination of tools, and if you own one you don’t have to carry all these different tools with you.  Although they are great tools, I suggest you be careful with them, and make sure you take all the safety precautions available.  Overall, if you learn how to use these multimeters effectively, it will make a lot of home repairs and on the job repairs a whole lot easier!
