One of the most frequently asked questions we get is about calibration certificates.
People get confused when our website offers a free calibration certificate with a tester, but also the option to add a calibration certificate for a price.
Well i am here today to explain the difference and benefits of both.
First off, the free calibration certificate. This is also known as a statement of calibration and many brand new testers come with one of these free certificates.
This is a standard certificate that states that your tester was working to specification when it left the manufacture’s factory most carry full test results.
In Fluke’s words “Fluke guarantees that at the time of test your instrument met its published specifications”
As the customer you validate the calibration by completing the commissioning date box using the date of purchase.
Again, in the words of Fluke “Because we use different delivery channels, you may have received a meter with a test certificate that is several weeks old. Our experience indicates the calibration of this product is not affected by storage prior to its initial receipt by the customer. Therefore, the recalibration of this unit should be based on when the product is put into service”.
This means that a free calibration certificate is valid for 12 months from receipt of purchase, not from when the manufacture initially tested it.
A calibration certificate that you pay for when buying a new tester is completely different. This service gives you a much more in-depth certificate.
The tester is booked into our system using the serial number, tested by instruments calibrated to national traceable standards, reference stickers are added and then the meter is shipped to you. You end up with a traceable calibration certificate with full printed test results, along with the serial number and company details. The paid certificate also shows your own company details, who tested your meter, what conditions the calibration was performed under, the equipment used and any additional results found. A lot of people need this sort of detailed certificate for their inspections, mainly due to the fact that the serial number and company can be tied in together to the tester. The reference sticker on the tester will also show the date calibrated and what date the calibration runs out, so you never get caught short just before inspection day.
So there we have it, a free calibration certificate is a perfectly legal calibration certificate which is valid from the date of purchase. A paid calibration certificate is a detailed inspection and calibration service with in-depth results and information.
