We focused our testing on a network cable tester that measures total data because these give the most accurate picture of your output.


While single-sided power meters are typically cheaper, they also assume your power balance (the percentage of total power each leg is producing) is perfectly even at all times. Our experience using dual-sided power meters (which measure power output from each leg independently) shows this isn’t the case, though.

The professional team’s testing took into account ease of installation, how each network cable tester performed, and whether it’s likely to stand up to long-term use.

What to Consider Before Choosing the Best network cable tester

Whether you are a pro or a DIYer, it is wise to consider the style, features, accessories and leads when choosing a network cable tester. There are many options out there. Consider these features before purchasing one of these tools to help speed up the process.

Basic and Advanced Functions

If you want the greatest versatility from your network cable tester, make sure it can test both types of current: alternating current (AC) — electricity flowing through outlets in your home — and direct current (DC), the electricity stored in batteries. Moreover, a network cable tester must perform at least two of the following three electrical tests in order to qualify as a network cable tester:

  • Current: How fast electricity circulates
  • Voltage: The difference between the electric current flowing between two points
  • Resistance: The amount by which the material carrying the energy resists electrical flow, such as wires

In addition to testing voltage, resistance, and current, advanced digital network cable tester can often perform the following tests:

  • Capacitance: Storage of ectricrical charge
  • Temperature: The degree of heat generated within the circuit (frequently in both Fahrenheit and Celsius).
  • Frequency: Electrical occurrence rate (measured in hertz)

Analog Versus Dial Display

network cable tester with analog dials that have needles (like an old-time speedometer on a car). In bright sunlight, it can be challenging to read a digital readout, especially when numbers are hard to read. The number of analog meters has dropped, but they are still inexpensive, ranging from $10 to $70, and they can perform the three basic circuit tests; they cannot perform more advanced tests.

In today’s market, most network cable testers is electronic, and they’re more expensive, ranging from $20 to $500, or even more, depending on quality and precision. In addition, some digital network cable testers feature backlit screens to make them easier to see in bright light; others have auto-shutoff features that turn them off after a few minutes of inactivity.

Auto-Range Function

With a manual range network cable tester, it can be difficult to determine the approximate range of electrical current you’re testing. Having set the network cable tester to a specific ohms range, you need to keep clicking until the network cable tester provides a reading. network cable tester with an auto-range function (available on digital models only) will save you time since you only need to choose the type of test to perform (voltage, resistance, and current). A readout will appear immediately after the meter matches the right range to the circuit by scanning through all the range options.

Choosing a Network Cable Tester – What to Look for

There are many different types of network cable testers available on the market. Here are some examples. Each device has its own set of distinguishing characteristics that distinguish it from the others. Choosing the most appropriate one for your requirements, on the other hand, can be difficult.

This is where the information in this buying guide will come in handy. Allow us to educate you of the characteristics that will assist you in selecting the most suited gadget from the available network cable testers.

You only need to go over the elements we’ve described below and decide which ones are the most effective for you, as well as which brands we’re about to recommend to you. But first, let’s have a look at some of the considerations to bear in mind before purchasing one; this will be especially useful if you’re purchasing one for the first time:

Compatibility with cable

Only a few of the network cable testers would be suitable for your needs; in fact, several might not even fit the parameters of your requirements when used remotely. For this reason, you should carefully verify whether or not the cable tester you are about to purchase is compatible with the cable types you will be testing.

Consider the following scenario: you work in the electronics business and are frequently dealing with cables and powerline connections. If this is the case, we recommend that you invest in a multi-purpose cable tester that is practically compatible with all cable varieties. Remember that certain testers can connect to a range of different cable types. Some, on the other hand, may necessitate the use of an adaptor for this reason.

Ease of use

When selecting a network cable tester, you should first consider its practicality and versatility, and then consider its price. Due to the possibility of having to measure large wires, the tester should be extremely efficient. The tester assists you in comprehending everything without the need to switch between several panels. Choose a tester with a lightweight and simple design that is straightforward to use.

LED/LCD Display for the On-Tester

The majority of network cable testers have a display screen that shows the results of the tests. But be aware that some testing does not have a display screen and instead only delivers results by sound or light indicators, so make your selection carefully!

We strongly advise you to choose a tester that includes some form of display screen—you already know why! If you’re in a noisy location, you might miss the sound, or the LED indicator might not blink at the appropriate time. Although it is rare that you will forget about the readings if you are using a display (LED or LCD) indicator, it is nevertheless possible.

It goes without saying that if you are a professional technician who needs to measure the voltage of a cable line, a display-type tester is a must-have tool in your toolbox. In contrast, non-display testers are substantially less expensive than display testers, which is a big advantage. So, the bottom line is to choose the one that you believe will be the most beneficial.

Fourth, the testing method Network cable testers may perform a wide range of cable tests, including voltage and continuity tests as well as resistance and cable length tests. They can also perform pin testing and cord connection evaluations, among other things.

You must first determine exactly what you intend to use the cable tester for. This is critical since only a few network cable testers are capable of performing a single test type, while others are capable of doing many tests. Consider the kind of tests that will be performed before making your selection from the list of the best network cable testers provided below.

The ability to do Length Testing

It is vital to understand the maximum length that a cable tester is capable of testing. Due to the fact that network cable testers have a limited range of operation when it comes to assessing and inspecting the quality of cord connections,

Inaccurate readings or results from network testing may be obtained if the maximum cable length recommended by the device is not adhered to.

Limited Warranty Period

Purchasing a warranty for your product ensures that you will not need to worry about anything for a specified length of time. All you have to do now is tell the firm, and your problem will be remedied immediately. You are covered as long as your tester is within the warranty period.

Because network testers are electronic equipment, they are certain to malfunction if they are subjected to extremes of heat and cold, as is the case with most electronic devices. For this reason, you should always keep track of how long your tester’s warranty is still valid. Although it is possible to extend your warranty for a few dollars more, this is not always recommended.


With a bigger price tag comes more features and longer useful life for your goods and services. Because a longer-lasting tester will save you money in the long term, it is good to spend a bit extra money upfront on it. Spending money on “additional features” that you do not require, on the other hand, is still a waste of your money in this case.

The types of tests that can be performed by your tester affect the price of your tester, as well as the types of cables that it can support, the construction quality, and so on. The issue can be complicated, which is why we are here to assist you in selecting the most appropriate option for your requirements.
