Below are general answers on how to operate, maintain, and calibrate an LCR meter from the list of GAO Tek’s LCR meters. To facilitate our customers to a selection of 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.

Operating an LCR Meter:

Power On:

  • Connect the LCR meter to a stable power source.
  • Turn on the power switch and allow the instrument to warm up for a few minutes.

Select Measurement Mode:

  • Most of our LCR meters have different measurement modes such as L (inductance), C (capacitance), R (resistance), and combinations like LC, RC, and LCR.
  • Use the mode selector to choose the appropriate measurement mode for your component.

Set Test Frequency:

  • GAO Tek’s LCR meters typically operate at specific frequencies for accurate measurements. Choose the desired test frequency based on your application.
  • Some meters allow you to set the frequency manually, while others may have preset values.

Connect Test Leads:

  • Connect the test leads to the appropriate terminals on the LCR meter. Ensure proper connection polarity for accurate readings.
  • Connect the other end of the test leads to the component under test.

Zero Adjustment (Optional):

  • Some of our LCR meters have a zero-adjust function to compensate for any stray capacitance or inductance in the test leads. Follow the instrument’s manual to perform zero adjustment if needed.

Initiate Measurement:

  • Press the measurement or test button to initiate the measurement. GAO Tek’s LCR meter will provide readings for the selected parameters.

 

Maintaining an LCR Meter:

Clean the Terminals:

  • Regularly clean the test terminals using a soft brush or compressed air to remove any dust, dirt, or oxidation that may affect measurements.

Handle with Care:

  • Treat the LCR meter gently and avoid dropping it or subjecting it to physical stress.
  • Store the instrument in a clean, dry environment when not in use.

Calibration Check:

  • Periodically check the calibration of the LCR meter to ensure accurate measurements. Calibration may drift over time or with environmental changes.

Update Firmware (if applicable):

  • If your LCR meter has firmware that can be updated, check for updates and apply them as needed to enhance performance and add features.

 

Calibrating an LCR Meter:

External Calibration Standards:

  • Use external calibration standards like precision resistors, capacitors, and inductors with known values to calibrate the LCR meter.
  • Follow the calibration procedure outlined in the instrument’s manual.

Internal Calibration (if available):

  • Some GAO’s LCR meters have internal calibration routines. Follow the manufacturer’s instructions to perform internal calibration if applicable.

Verify Accuracy:

  • After calibration, verify the accuracy of the LCR meter by measuring known components. Compare the readings to the expected values to ensure calibration success.

Document Calibration:

  • Keep detailed records of calibration procedures, dates, and results. This documentation is crucial for quality control and traceability.
