Below are general answers on typical components of a LCR meter from the list of GAO Tek’s LCR meters. To facilitate our customers to select our products, we have further classified our LCR meters by their features: auto shut-off, benchtop, data logging, handheld, high frequency, high precision, industrial, laboratory, and rugged.

We have products in stock and can ship overnight to most places in the U.S. and Canada.

Measurement Circuitry:

  • Inductance Measurement Circuit: GAO’s circuit typically uses an oscillator to generate an AC signal, which is then passed through the inductor under test. The resulting voltage and current waveforms are analyzed to determine the inductance.
  • Capacitance Measurement Circuit: Like the inductance measurement, our capacitance measurement circuit uses an AC signal. The behavior of the capacitor under the AC signal is analyzed to determine the capacitance.
  • Resistance Measurement Circuit: Our resistance measurement is usually done using a DC measurement technique. The meter sends a known DC voltage through the resistor and measures the resulting current to calculate the resistance.

Display Unit:

  • Our display unit shows the measured values of inductance, capacitance, and resistance. It may also display additional information such as test frequency, equivalent series resistance (ESR), and quality factor (Q).

Controls:

  • Function Selection: Our switches or buttons allow the user to select the type of measurement (inductance, capacitance, or resistance).
  • Range Selection: We allow the user to choose the appropriate measurement range for the component under test.
  • Frequency Selection: GAO Tek LCR meters allow the user to select the test frequency for the measurements. Different frequencies may be suitable for different types of components.

Connectors:

  • We test terminals or connectors for attaching the component under the test. These are typically banana jacks or specialized connectors.

Power Supply:

  • GAO Tek LCR meter requires a power supply to operate. This could be batteries for portable units or an external power source for benchtop models.

Microcontroller/Processor:

  • The microcontroller or processor is the brain of the LCR meter. It controls the measurement process, processes the data, and communicates with the display unit.

Software:

  • Our LCR meters may have firmware or software that allows for additional features, such as data logging, connectivity with a computer, and firmware updates.

Calibration Circuitry:

  • GAO’s LCR meters ensure accurate measurements. Calibration circuits and routines are implemented to compensate for any drift or inaccuracies in the measurement circuitry.

Mechanical Enclosure:

  • Our components are housed in a sturdy enclosure to protect them and provide a user-friendly interface. The enclosure may include a handle for portability in the case of handheld models.

Connectivity Options:

  • Some of our LCR meters may include USB, RS-232, or other interfaces for connecting to a computer for data logging or analysis.
