Electrical Calibration
Rezonans Kalibrasyon — Electrical Calibration Laboratuvarı

Our electrical calibration services are performed to cover AC/DC voltage, current, resistance, frequency, and capacitance measurements across various ranges. Calibration processes are carried out using the comparison method according to instructions prepared in line with the Euramet CG-15 guide and relevant international standards.

Measurements in our laboratory are conducted by connecting to high-voltage reference devices up to levels of AC 28 kV and DC 40 kV. An accredited calibration certificate is issued for all measuring instruments once the calibration process is completed.

To ensure measurement accuracy and traceability, our company utilizes reference calibrators that are calibrated to be traceable to SI units. All our services are conducted within the framework of the ISO/IEC 17025 standard.

Frequently Asked Questions

What is electrical calibration?

Electrical calibration is a verification process performed by comparing measuring instruments with reference devices to determine if they are measuring accurately. This process guarantees the measurement accuracy of the device.

Why is a calibration certificate necessary?

A calibration certificate shows that the device’s measurement results comply with international standards and are verified in a way that is traceable to reference instruments. It is mandatory, especially in quality management systems.

How often should calibration be performed?

Generally, measuring instruments are calibrated once a year. However, this period may change depending on usage intensity, the operating environment, and quality standards.

Can high-voltage test equipment be calibrated?

Yes. In our laboratory, calibration of high-voltage measuring instruments up to AC 28 kV and DC 40 kV can be performed.

How long does the calibration process take?

Depending on the type of device and the scope of the tests, the calibration process is generally completed within 1–3 business days.
