Electrical Calibration

Electrical measuring instruments form the backbone of industrial facilities, energy distribution centers, and electronic services. Over time, these devices can undergo value shifts due to environmental factors and intensive use. Rezonans Calibration provides electrical calibration services in compliance with TS EN ISO/IEC 17025 standards for all your devices—from multimeters to oscilloscopes—using high-accuracy reference calibrators.

The accuracy of electrical parameters (Voltage, Current, Resistance, Capacitance, etc.) directly affects not only device performance but also your business’s occupational safety and energy efficiency.

What is Electrical Calibration and Why is it Necessary?

Electrical calibration is the process of determining the error margins of test and measurement instruments by comparing them against high-precision electrical sources that are traceable to national or international standards.

The primary benefits of regular electrical calibration include:

Device Reliability: Ensures your measurement results are always accurate and repeatable.
Occupational Safety: Prevents electrical accidents and equipment damage caused by faulty or incorrectly measuring devices.
Energy Efficiency: Minimizes energy losses through precise measurements.
Quality Standards Compliance: Meets legal requirements in audit processes such as IATF 16949, ISO 9001, and ISO 45001.

Technical Methodology of Rezonans Calibration

Error margins are unacceptable in electrical measurements. Therefore, we manage our processes with the utmost precision:

Stable Ambient Conditions: Electrical measurements are performed in a controlled laboratory environment unaffected by static electricity and temperature fluctuations.
High-Precision References: Every range of your device is tested individually using our Multi-product Calibrators.
Traceable Certification: Measurement results are converted into certificates with TURKAK traceability, including a measurement uncertainty budget.
Fast Turnaround: We operate with a dynamic appointment system to minimize the time your test and measurement tools are away from production.

Why Should You Work With Us?

Accredited Laboratory: Internationally valid reporting and certification.
On-Site Service: Availability of on-site calibration for panel-type devices and energy analyzers that are risky to dismantle.
Wide Scope: Competence in all electrical parameters from current to resistance, frequency to voltage.
Expert Engineering: Technical consultancy support in the calibration of complex devices.

Frequently Asked Questions

What should be the calibration period for electrical devices?

The general recommended period for electrical devices is 12 months. However, it is recommended to check devices used very frequently or operating in harsh field conditions (dust, humidity, impact) every 6 months.

Do you perform device repair as a result of calibration?

Calibration is a measurement process, not a repair. However, if a deviation beyond the limits is detected in your device, our technical team will inform you about the adjustment of the device or its referral to an authorized service.

Which values are checked in clamp meter calibration?

In clamp meters, a full electrical verification is performed by checking both the current measurement capacity (amperes) and, if available, the voltage, resistance, and continuity functions.

Are your certificates valid in audits?

Yes, certificates issued by Rezonans Calibration are documents that meet all the requirements of ISO 9001 and other international quality management systems and are fully accepted in audits.

Is on-site electrical calibration possible?

Yes, we provide on-site services with our mobile calibration teams, especially for measuring instruments connected to fixed panels in factories, energy analyzers, and devices that are difficult to dismantle.
