LCR Meters

An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. Typically, handheld LCR meters have various test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz for top end meters. The LCR meter is controlled by a high-speed microcontroller with an embedded logic that controls the display and keypad, along with setting measurement conditions and performing calculations.

GAOTek has worked diligently to developed advanced LCR meters that are high in quality, affordable in comparison to the current market, and accurate. They are very versatile instruments for the measurement of the inductance, capacitance, and resistance of passive components. We have a wide variety of LCR meters with the simplest operation. With accurate measurements, we ensure that you will be satisfied when using our products.

GAOTek LCR meters are top notch when it comes to quality and high accuracy readings. The process can be done in an effective and efficient way with GAOTek various types of LCR meters.

Technologies

In today’s technology, there are various types of LCR meters. The two most prominent are handheld and benchtop LCR meters, which are significantly different from each other; one is more portable than the other, but in most cases the latter is more powerful than the former.

·         Handheld LCR Meters, unlike its counterpart, have the advantage of lightweight portability as well as being battery operated. These devices are designed for general applications, especially in field maintenance and various service applications. Dedicated handheld LCR meters use an AC type signal and offer more impedance parameters, such as AC resistance and inductance, than a typical handheld DMM with a capacitance feature.

·         Benchtop LCR Meters generally offer more features than the handheld version, such as programmable frequencies, more precise measurement accuracy, computer control, and data collection for automated applications. Advanced features, such as DC bias voltage, DC bias current, and sweep capability are more common. LCR meters in this category are typically used for AC calibration of inductance, capacitance and resistance standards, dielectric constant measurements with a variety of dielectric cells, and production testing of components and sensors.

An LCR meter has two DUT (Device Under Test) jacks, which is the positive and negative. These jacks are used to connect the tweezers that are being attached to the electronic components being measured. An IR port is also part of the LCR meter which allows data to be transferred between another IR-equipped device. One of the most important components of an LCR meter is also the calibration button port. It effectively eliminates a significant number of minor errors that could potentially affect the device’s measurement accuracy. The LCR meter is a useful instrument to have on hand both in the field and in the lab.

Features

GAOTek LCR Meters offer a lot of key features that are helpful in operating the device easily and for an accurate reading. Below is a list of key features that the GAOTek LCR Meter offers:

·         Frequency up to 100 kHz: The test frequency now extends as high as 100 kHz, providing more flexibility to test a wider range of components. A higher test frequency, for example, 100 kHz, is useful for applications such as aluminum electrolytic capacitors testing used in switching power supply circuits

·         Automated identification: with Ai, the testing and measuring experience has been simplified; error time and unnecessary trials are eliminated with a single push of a button. This modern feature automatically specifies L, C, or R with parallel and series mode. The user no longer requires to manually change buttons.

·         Detailed component analysis: The Handheld LCR Meters allows you to test various types of components, including secondary components of Dissipation Factor (D), Quality Factor (Q), and Angle Indication of Impedance (θ)

·         Test Fixtures: the LCR Meters have a Kelvin fixture that utilizes two wires to carry the two independent wires, and then tests the current to sense the voltage across the instrument under test. This prevents the voltage drop in the current carrying wires from affecting the voltage measurement

·         Battery life of 16 hours/AC-powered 

·         IR-to-USB connectivity for data logging to P

·         Back light function to ease viewing in subdued lighting

·         Low Battery Indication

·         Auto Power Off

In addition to all these features, our products have a high precision of measurement capabilities, high resolution, and quick sampling speed. More importantly, our products are also affordable when it comes to tight budgets. Users can have different options to choose from with all the various kinds of LCR Meters manufactured by our company.

Applications

LCR meters are commonly used in research, development, and testing of electronic equipment including power supplies, transformers, and electrical motors. Sometimes referred to as an impedance analyzer, an LCR meter comes in benchtop models for use in the lab and handheld models for use in the field or manufacturing floor. LCR meters commonly have an LCD screen to display readings and measurement settings. The LCR meter is a device that is simple to operate to different applications. The GAOTek LCR Meter measures passive components with as little as 0.05 % errors and is quick to setup, adjust and calibrate. In addition, they are also ideal for applications such as incoming inspection, quality control, automated test, and general bench top use.
