Calibration means comparison with a known standard quantity. This quantity is represented by a national standard which, in turn, is traceable to the so-called SI units – the physical quantities of the international system of units.

Regular calibration is important for maintaining high measurement accuracy in the long term. This is important, since incorrect measurements could lead to claims for damages in the worst cases.

Narda Safety Test Solutions GmbH has three of the most up to date calibration laboratories located in different parts of the world:

• in Pfullingen, Germany
• in Hauppauge, New York, USA
• in Cisano sul Neva, Italy

These laboratories are equipped to perform calibration over an extremely wide frequency range, from 5 Hz to 60,000,000,000 Hz (60 GHz). The calibration is an integral part of an ISO 9001-certified management system. The test equipment management for the metrological certification system conforms to ISO 10012-1.

Factory calibration

Factory calibration does not simply mean checking the specifications. A comprehensive function test and minor preventive maintenance are also performed, improving the reliability of the test equipment and preventing failures. At the same time as a calibration, you can also request a firmware update to make sure your instrument has all the latest features.

All factory calibrations are performed in our own laboratories.

Scope of factory calibration

• Test of major instrument functions
• Hardware modifications for product improvement
• Preventive test for the effects of wear and tear
• Small repairs
• Checking and replacement of buffer battery
• Exchange of main battery (depending on instrument type)
• Backup of customer’s measurement data and setups (depending on instrument type)
• Firmware update
• Calibration of all major parameters to manufacturer’s specifications
• Documentation of measured values before and after calibration
• Documentation of traceability to SI units
• Alignment and adjustment if tolerance values are exceeded
• Indication of exceeded tolerance values entered in calibration report
• Instrument cleaning
• Calibration certificate with measurement results and measurement uncertaintydata
• Calibration stamp

If your instrument needs repairing, we will send you an estimate of the cost. The suggested repairs will not be performed until you have agreed to the estimate.

We recommend that you should have our instruments and probes factory calibrated every 24 months. Details about this are given in the instrument data sheets.

Calibration by an accredited laboratory:

Our calibration laboratory in Cisano sul Neva, Italy, is accredited by the Italian national authority SIT (Servizio di Taratura in Italia).

You can find more information at www.narda-sts.it

Or, e-mail us at support@narda-sts.it

Preparation is in progress for accreditation of our laboratory in Pfullingen, Germany, by the DKD (Deutscher Kalibrierdienst).

Our calibration laboratory in Hauppauge, New York, USA provides calibration to NIST or ANSI standards.

NIST calibrations are traceable to the standards of the National Institute of Standards and Technology

ANSI calibrations conform to Regulation Z540-1-1994 of the American National Standards Institute and are comparable with the earlier MIL-STD-45662A.
