Calibration and servicing of your noise measurement equipment is vital to ensuring that it continues to meet the specifications it did when it was new. Many factors can affect the performance of noise measurement instruments and so an annual check-up is the best way to ensure that your equipment is still operating as it was intended to do.

If you are working any standards that requires the use of noise measurement equipment, the standards to which the equipment must comply will be clearly stated. Your instrument may also need to be repaired if it has been damaged or is not working correctly.

It is recommended that recalibration of noise measurement instruments is carried out annually because your instruments and calibrators are sensitive precision equipment. Over time, due to movement and use, they require adjustment to ensure that the measurements you are taking remain accurate, helping you to avoid potential errors in your noise measurements.

Annual servicing is like an annual check up for your equipment. This will involve a thorough check of the performance of the instrument, may allow for software updates and improvements to be installed as well as prolonging the life of your investment.
