CALIBRATION
Every meter that reaches us is important to us and we treat each one with the utmost care.
The calibration process consists in comparing the indication of the calibrated instrument with the indication of the reference instrument. The reference instrument is much more accurate than the calibrated instrument. However, the calibration results along with their uncertainties are presented in the calibration certificate.
Let's summarize. The whole process looks like this.
1.
Send order form on website
2.
Deliver the instrument using available methods
3.
Confirm the terms of the order sent by e-mail (optional)
4.
Make a payment for the order
5.
We return the device by courier
When to calibrate?
SONEL S.A. recommends performing calibrations at least every 12 months for its instruments.
Why regular calibration?
See examples
ReadFor brand new instruments put into service, the next performance confirmation is recommended to be carried out within 12 months from the date of entry into service (date of purchase), but no later than 24 months from the date of the first check. The next inspection is carried out by the Testing and Calibration Laboratory of Sonel S.A., and the issued document is called Calibration Certificate (instruments having the character of a standard) or Declaration of Verification (indicators, testers without the character of a standard).
The meters are calibrated at SONEL S.A. headquarters, at str. Wokulskiego 11, 58-100 Świdnica, Poland.
Only an actual calibration certificate certifies the metrological properties of a calibrated measuring meter!!
In the case of meters used for testing relating to protection against electric shock, the person carrying out the measurements shall have all confidence in the performance of the device used.Measurements made with an inoperative meter may contribute to an incorrect assessment of the effectiveness of protection health and even human life.
CALIBRATION CERTIFICATES
with PCA accreditation are recognized worldwide
This document defines the relationship between a standard and an indication of a meter and states the uncertainty of measurement.
The competence of the Testing and Calibration Laboratory of SONEL S. A. has been confirmed by an independent third party. Calibrations are performed according to standard procedures or based on individual customer requirements. The laboratory shall use methods of direct or indirect comparison to a standard, which are described in internal instructions.
