LCR Meters

An LCR meter is used to measure the inductance (L), capacitance (C) and, resistance (R) of an electronic component. In general versions of an LCR meter, these measurements are derived by measurement of impedence. The necessary calculations are, however, incorporated in the instrument’s circuitry, so the meter reads L, C and R directly with no human calculation required.

GAOTek’s advanced LCR meters 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 positive and one negative DUT (Device Under Test) jacks. These jacks help to connect the tweezers that are being attached to the electronic components for taking measurements. An IR port in the LCR meter allows data to be transferred between another IR-equipped device. There is a calibration button part which forms an important component of an LCR meter. It helps in improving the accuracy by eliminating a significant number of minor errors. 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

GAOTek's LCR Meters measures passive components with as little as 0.05 % errors and are 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. The LCR meters are very useful in the research and development, testing of electronic equipment including power supplies, transformers and electrical motors. An LCR meter is also used to measure the capacitance in air and with the material or liquid in the cell.
