How often should I calibrate my instruments?

There is no legally defined time frame. In fact, the ideal timeframe depends on many factors: the use of the equipment, its method of storage, the internal processes within each company that determine maintenance, and the timeframes dictated by procedures linked to quality systems, such as ISO 9001. It is generally good practice to calibrate instruments annually.

Can I obtain the calibration on the same day?

Calibrating an instrument is a process made up of a number of mandatory steps, one of which is thermal conditioning: a 24-hour time interval that must precede calibration. This is why it is not possible to proceed with operations immediately after the arrival of the instrument.

Which documentation is required to calibrate the instrument?

The documents that must be provided are the delivery note and the order form with the details of the recipient of the certificate. Only in this way will we be able to immediately identify the instrument and start calibration according to the schedule.

Can I also calibrate instruments not manufactured by Senseca/Senseca?

Yes, our Centre is authorised to calibrate any instruments, whatever their brand is, according to our accredited quantities.

Do I have to send the accessories with the instrument?

Yes, the instrument shipped should work properly and it has to be correctly packed, complete with accessories and user manual.

What is the difference between Calibration and Adjustment?

The Calibration is an operation that defines the metrological characteristics of an instrument in order to establish its accuracy.
The Adjustment is a process which aims to make the measuring instrument more accurate by often improving its precision.

What benefits do I get by accrediting my instruments?

Demonstrating that you have accredited your instruments is undoubtedly a choice of transparency towards your customers. Not to mention that demonstrating accreditation is often a prerequisite for meeting the standards of potential customers.
Accreditation also puts companies in a position to be recognized internationally. In fact, customers can rely on the data reported in the ACCREDIA calibration certificate, which is also valid and recognized internationally.

What happens if I don't calibrate my instruments regularly?

The normal use of a measuring instrument exposes it to a natural ageing process which can lead to changes in the measured values. Through the calibration process, it is possible to detect these changes in time in order to avoid possible process interruptions or, depending on the type of instrument, possible safety risks.

Can I receive a copy of the calibration certificates for your primary samples?

It is not necessary for our Calibration Centre to produce this type of document to the customer, because the traceability of the metrological chain to national/international samples is given by the references of the sample, as well as those of its own calibration certificate.

Belonging to the ACCREDIA circuit guarantees that the centre's procedures and the equipment used for calibrations always correspond to the standards and are regularly checked by inspection visits. For further information: https://www.accredia.it/en/accredited-services/calibrations/

I have lost the calibration certificate/report of my instrument, what should I do?

In case of loss of the ACCREDIA Calibration Certificate, it is necessary to send an e-mail to calibration.padua@senseca.com and provide a loss declaration, quoting the certificate number or the serial number of the instrument. Our Calibration Centre will then issue a Copy Conforms to the Original of the Certificate. In case of loss of the calibration report, proceed as above. Our Calibration Centre will then reprint the report.

What are Accuracy and Precision?

The Accuracy of measure is not a quantity and it is not assigned a numerical value. A measurement is more accurate the less measurement errors there are. The Accuracy of measure is expressed numerically by measures of imprecision, such as standard deviation, variance or coefficient of variation under specified measurement conditions.
