A Helpful Guide to the Best LCR Meters

Anyone who has worked with electronic appliances before will know how precious an LCR meter is. An LCR meter helps you determine what the inductance, capacitance, and resistance of a certain electronic device are.

The frequency of this meter can either be chosen by yourself or can be relied on by the device to do it for you.

Today, we will be providing you with a helpful guide to the best LCR meters in the market from which you can decide which one you want to get for yourself. Read on to find out what features the best LCR meters have!

Features of the Best LCR Meter

Before we take a look at some of the best LCR meters out there, it would be helpful for you to know what exactly you should be looking for in your meter when you go to the shop to purchase it.

The Interface of the Data

Even though almost all good LCR meters have some amount of storage capacity which will store your data, what matters is how much data the meter will be able to store.

As a quick example, an LCR where you will be able to review your data analysis on a later date is much better than one which will only be able to show you a small number of data.

Similarly, some LCR meters will allow you to transfer your information to a computer, but it all comes down to how well-matched the meter is with your computing software.

Accuracy

LCR Meters Accuracy

Having the most accurate and precise set of readings will go a long way in improving the quality of your work. LCR meters are generally of two types: digital and analog. While some people may incline more towards analog meters, digital ones will provide the user with a higher accuracy rate.

Technically, a meter with a high accuracy level is one whose variance remains lower than 1%. Needless to say, these meters will cost you more than those that have a variance of more than 1% and consequently are less accurate.

Construction of the Meter

The construction of your LCR meter will determine how long it will last you.  Purchasing a properly guarded electronic circuit component will save you from spending extra money in the future in case if the appliance comes in contact with a large amount of force.

The Device’s Throughput

One of the reasons why this factor is so important is that if you use your LCR meter every other day, going through every option on the display screen that your meter has to offer may become quite frustrating.

With that being said, you should opt for a meter that has offers a small number of features, all of which are necessary and you know you will use at one point.

A Helpful Guide to the Best LCR Meters

Now that you know what you should be looking for in an LCR meter- let us go ahead and see what some of the best LCR meters are that you could choose from.

1. DE-5000 Handheld LCR Meter

The DE-5000 Handheld LCR meter is perfect for you if you wish to determine what the resistance of a Direct Current circuit or the impedance of an Alternating Current circuit is.

Due to its ability to be able to operate various testing factors, you also do not have to worry about having to skim through an unending list of distinct functions.

Aside from dealing with the three basic factors that an LCR is built for, the DE-5000 will also allow you to take into account other strictures such as the phase angle, the resistance of a parallel connection, and many more.

This LCR meter has measurements of 3.7 X .4 X 2.1 inches and comes in at a weight of just around a pound or so, hence making the appliance very lightweight. To start using it, you will first have to insert a 9V battery inside the meter.

The analog meter mainly sports a dark gray color, except for the buttons at the front, which have been given a yellow color. This helps the user difference between multimeter and LCR meter.

Moreover, you also do not have to spend too much time fretting over which button serves what purpose since their functions are quite straight-forward. In case if you wish to take readings using a different frequency, you will be given the option to choose from any frequency from 100Hz- 100 kiloHertz.

You will also be able to do a quick review of all the information you have collected for a specific experiment by simply activating the ‘sorting mode‘ of this meter.

The only downside to this meter is that it does not come equipped with an adapter of its own, and you will have to purchase one by yourself.

Since the instructions manual of this meter was composed in a foreign language, you will also get an email with a copy of the English version of the instructions book attached when you confirm your purchase.

2. Proster LCR Meter

This LCR meter is great for those who are looking for a highly-sensitive device that will let them measure small changes in a certain factor easily. The Proster LCR was made specifically to let users extract data on even small changes in the capacitance of an electrical circuit.

When working with more significant changes in capacitance, even a small amount of interference will not mess the data up completely. However, since this is not the case when working with minute changes in a factor, a sensitive device should be used.

The Proster LCR meter will be able to determine the inductance of a circuit component if the value falls within the range of 200 micro-henries to 20 henries. Moreover, it will be able to calculate any value within this given range with an accuracy of up to 2.5%.

Similarly, this meter will also be able to take readings for the resistance of a component within a fairly big range of 200 ohms to 20 mega-ohms. For the resistance measurement, the Proster LCR meter has an accuracy of ±0.8%.

This meter is slightly bigger than the one we have mentioned before, and it also weighs more than the DE-5000. Despite its large size (8.7″ x 5.3″ x 2.5″) and heavyweight (of around 590g), this LCR meter is extremely easy to use.

All you have to do to change the functions is to rotate the front dial in whichever direction you want to.

Apart from the front dial, you will also find a zero adjustment dial and a power switch along with a button labeled ‘DH.’ This button, when used, will auto-save the information on the screen.

Taking readings from different positions would not be that much of a hassle since the console of the display screen can be manually adjusted.

The only other downside to this device is that the display does not have a good backlighting system, hence making this meter difficult to use in rooms that are not well-lit.

If you are taking readings for the capacitance of your electrical circuit with this meter, you should expect an accuracy of around 2.5% for a range of 200 Pico-farads to 2000 microfarads.

The best part about this instrument is that it also has a feature that will tell you when the battery of the appliance is running low. This will cause you to never lose another set of data all of a sudden.

Moreover, if you ever forget to turn your meter off, you need not worry about it staying powered on all night. This is because the device is also designed to automatically turn itself off when it has not been used for a while.

Conclusion

We hope you found this article to be a helpful guide to the best LCR meters.  Do remember that the list is not limited to the few meters that we have mentioned above. Do not forget to look into a few details on your own before you confirm your purchase.
