Calibration
10.1 Why Invest in Calibration?
Properly calibrated equipment provides you with confidence that your products/services
meet their specifications.
Calibration is simply the comparison of instrument performance to a standard of known
accuracy. It may simply involve the determination of deviation from nominal, or include
correction (adjustment) to minimise the errors.
When you have your instruments calibrated regularly, you will have reliable measurement
data, you can compare data over time, and you can provide proof to customers, besides
fulfilling internal or external quality requirements.
As components age and equipment undergoes changes in temperature or sustains mechanical
stress, critical performance gradually degrades. This is called “drift”. When this happens,
your test results become unreliable and both design and production quality suffer. While
drift cannot be eliminated, it can be detected and contained through calibration.
10.2 PULSE Services at Brüel & Kjær
10.2.1 Service Agreement
With Brüel & Kjær your instrument can be calibrated and maintained at the same time. With
a Service Agreement you can save both time and money. The value of a Service Agreement
lies in a combination of:
• Assurance that the time your instrument is away for service is minimised
• Attractive total service price
With planned service your instrument is available at the time you set up for measurements
and you have proof of correct data.
If during calibration the technician finds a need for repair, this will be done while your
instrument is in our hands. You don’t have to be without your instrument several times.
