Analyzer calibration

Brüel & Kjær can provide accredited calibration, traceable calibration, and instrument verification for all of our analyzers. Both accredited and traceable calibration for our PULSE analyzers are available. These keep your measurements accurate and verifiable.

Data acquisition / analyzer front-ends

We recommend that you calibrate your PULSE front-ends regularly. This will help you:

• Know if values have shifted in any of the channels
• See data indicating whether the instruments are drifting 
• Prove measurement traceability
• Prove calibration of the entire measurement chain

An accredited calibration ensures that the analyzer measures correctly in the specified measurement range.

Accredited calibration

Brüel & Kjær can provide these types of accreditation for PULSE:

• DANAK (English certificate)
• A2LA (English certificate)
• DAkkS (German certificate)
• CNAS (Chinese certificate)
• NATA (English certificate)

Initial calibration

We recommend that you order accredited calibration together with your new PULSE Analyzer, to start your calibration history from the very outset.

Re-calibration

With annual calibration data, you create and maintain an unbroken calibration history to use as a reference. This can be useful either for internal requirements, for auditing required by authorities, or at the request of your customers. The shorter the period between calibrations, the lower the risk of questionable measurements.

Measurements

For PULSE analyzers the calibration measurements and acceptance limits are selected in accordance with the manufacturer’s specifications. Measurements are traceable to institutions such as DPLA, NIST, NPL and PTB.

Add-on calibration products

• Calibration according to sound level meter standards - optionally, PULSE modules (LAN-XI and Types 3560-B, -C, -D, -E) will be default calibrated according to Sound Level Meter Standard IEC 61672, or on order to IEC 60651
• Filter calibration – calibration of filter response for 1/1-octave and 1/3-octave filters according to IEC 61260 for the range 6.3 Hz to 20 kHz. You specify the number of filters you need

Certificate

With our accredited certificate, you receive:

• Proof that calibration has been performed according to the quality requirements in ISO 17025
• Measured frequency response with associated uncertainties
• Internationally accepted certificate with the logo of the accreditation body
• Calibration conditions: air temperature, air pressure, and relative humidity

Traceable calibration

Measurements

For PULSE analyzers the calibration measurements and acceptance limits are selected in accordance with the manufacturer’s specifications for PULSE version 8.0 and later. Measurements are traceable to institutions such as DPLA, NIST, NPL and PTB.

Certificate

The certificate includes all measurement results.

Verification/conformance testing

A conformance test certifies that the instrument has been tested, has passed all production tests, and complies with the manufacturer's published specifications. You will receive an official Certificate of Conformance.

Please note that instrument verification does not contain measurement results.
