Calibrating a Fluke multimeter involves a series of steps to ensure its accuracy and performance meet the required specifications.
Here’s a general guide on how to calibrate a Fluke multimeter:
Table of Contents
Preparation
- Ensure you have a suitable calibrator, such as the Fluke 5522A Multi-Product Calibrator, which should have specifications at least four times more precise than the multimeter being tested.
- Gather the necessary equipment, including compatible test leads and any other accessories.

Safety Precautions
- Only qualified personnel should perform calibration to avoid electric shock or injury.
- Ensure the multimeter is turned off and disconnected from any power source before starting the calibration process.
Calibration Procedure
- Direct Voltage Calibration:
- Connect the V and COM terminals of the multimeter to the NORMAL outputs of the calibrator.
- Set the multimeter to direct voltage mode.
- Select a known voltage output from the calibrator (e.g., 10 V) and adjust the calibrator to match this output. Verify the multimeter reading against the calibrator’s output.
- Resistance Calibration:
- Connect the multimeter to the calibrator using the appropriate settings for resistance measurement.
- Set the calibrator to a known resistance value (e.g., 100 ohms) and adjust the multimeter to read this value accurately.
- Other Measurements:
- Repeat similar steps for other functions like alternating voltage, capacitance, and current, ensuring each function is tested across its range[1].
Verification and Adjustment
- If the multimeter fails any performance tests, perform calibration adjustments as needed. This may involve recalibrating specific functions or ranges to bring them within specification.

Documentation
- Record the calibration results and any adjustments made. This documentation is essential for maintaining a calibration history and ensuring compliance with any regulatory or quality standards.
Final Checks
- After calibration, perform a final check to ensure all functions are operating correctly and the multimeter is ready for use.
Regular calibration, typically on an annual basis, is recommended to maintain the accuracy and reliability of the multimeter.
Frequently Asked Questions
Why should you calibrate a multimeter?
Calibration is essential for maintaining the accuracy and reliability of measurements, especially in critical applications. It involves comparing the multimeter’s measurements against a known standard to verify its accuracy. Factors such as the frequency of use, environmental conditions, and specific industry standards may influence the calibration interval. For instance, instruments used in high-precision or regulatory environments might require more frequent calibration.
How often do you need to calibrate Fluke Multimeters?
Fluke multimeters typically require calibration once a year to ensure they continue to perform within their specified accuracy limits. This annual calibration interval is a general guideline provided by Fluke and is based on the typical drift and wear of electronic components over time.
While some users may extend the calibration interval based on their specific needs and past performance of the instrument, adhering to the manufacturer’s recommended schedule helps ensure the multimeter remains reliable and accurate for professional use.
