How to Achieve the Best from Your LCR Meter


Practitioner engineers know that they shouldn’t measure inductance, capacitance, and resistance using different devices. There is one instrument which can measure them at the same time; it is called LCR meter. Now times have changed and with new tools, professionals can obtain even more precise results than ever. Do you know how to get the most from your measurement device without spending hours on playing with him? Then, there are some hints from experienced users which anyone can use from this day on.

Special Hints and Techniques of Using an LCR meter

Before people start using their first measurement device, they should take into account these estimation techniques:

  1. Use your test frequency as close to the operational frequency as possible. This way an effect of any stray changes of frequency will not impact your results;
  2. Your amplitude should be adjusted the same way: if someone uses an amplitude which differs, this variation might make his results imprecise;
  3. Adjust a lead length: your lead length may affect your results if its frequencies are around 1 MHz so you should be very attentive to it;
  4. After any measurement, you should discharge your capacitors because some of them may have a residual charge which can make your results higher than necessary.

If you have already bought one of the powerful LCR meters on Toolboom, you should know what to do before making your first measurement. If that is the case, the first thing you should do before making any estimations is to discover a direct current of a measured component. Then you should consider which level of precision do you need. Also consider frequencies of your components (typically, the smaller is your device, the higher is required level of frequency) because you will get imprecise results by making improper adjustments. After all, adjust your coil to both positive and negative terminals and start using your device.

Does the Form Matter?

One of the most frequent questions most beginner engineers ask is whether it is enough to use a handheld device or we need to spend money buying large benchtop instruments. Powered by a battery and being portable, handheld devices become more useful. Engineers who use more compact devices can bring them in any place without even having a car. However, when it comes to benchtop they have the highest level of capacity and make measurements with higher precision. Some ask a question: do we need to sacrifice precision in order to make our device easier to handle?

Professionals cannot tell you the exact solution because it all depends on your needs. If you appear not a professional engineer, then you will not need such a high level of precision and a handheld tool powered by the battery will seem enough. If you need to measure something really complicated, even an LCR meter will not be enough. You will anyway need a car to keep that entire staff so transporting additional  tools will not cause a trouble.

Anyway, you have a lot of online stores where you can buy these tools cheaper, try and check for that.
