9.6 Services at Brüel & Kjær for Types 2250 and 2270

9.6.1 Accredited Calibration

For Types 2250 and 2270, you can order accredited calibration and choose between DANAK,

A2LA, UKAS, Eichamt (Austria), RvA, ENAC, NATA and Inmetro.

For Spain, Primitiva is available.

The calibration will be performed in an ISO 17025 certified laboratory.

9.6.2 Initial Calibration

To start the measurement history from day one – if this is required, for example, for measurement

use in public, for customer audit or quality procedures – we recommend you order accredited

calibration together with the new analyzer.

9.6.3 Regular Recalibration

To fulfil requirements for public measurements and to minimise the cost of errors due to faulty

or inaccurate measurements, we can arrange for calibration every year in an ISO 17025

certified laboratory at Brüel & Kjær. With annual data, you will have an unbroken history to

use as reference, either for internal requirements, for audit required by authorities or at the

request of your customers. And not least, you can follow the history of sensitivity for your

analyzers over time.

9.6.4 Filter Calibration

• You can order calibration of filters. Please specify at the time of ordering

• Calibration of filter response for octave and 1/3-octave filters according to IEC 61260

9.6.5 Service and Repair

The hand-held analyzer is designed and constructed to provide many years of reliable

operation. However, if a fault occurs that impairs the analyzer’s correct function, then remove

the battery pack and disconnect any external power supply to prevent risk of further damage.

For more information about preventing faults or damage to your analyzer, see section 9.5.

9.6.6 Hardware Maintenance and Repair

You can minimise the risk of unexpected costs by purchasing the hardware maintenance with a

five years warranty. Minor repairs, such as those resulting from damage caused by unauthorised

use of the analyzer, can be performed at the same time as the analyzer is being calibrated at

Brüel & Kjær. This will save you time. If any other errors are detected by the technician during

calibration, repair will be performed before returning the analyzer to you.

Repair is available at a fixed price, which includes a Conformance Test Certificate upon the

return of your analyzer (no measurement data included).
