10 Second Survey Results: How often should you have your test meter calibrated?

Posted by Elaine Hammond on 22nd June 2017

The results are in!

We recently ran a 10 Second Survey to find out how often you think your test meter equipment should be calibrated. To ensure traceability to national standards, all testing equipment needs to be tested on a regular basis, but we wanted to see just how often you think that should be.

So, here are the results:


We were also interested to find out how long it has been since you last had your test meter calibrated: 



As you can see from the results above the majority (82.19%) agree that meter equipment calibration should be completed yearly. However, the frequency of testing can depend on a number of factors, for instance, your scheme provider may require you to have a certificate to prove your meter equipment readings are accurate, plus it could be a requirement of a contract you are working on.


For those who are concerned about the accuracy of their test meters, investing in a CalCard, which is approved by the NICEIC and NAPIT, is a great way help regularly check the accuracy of multi-functional test instruments. This is useful if you are working on electrical equipment and installations where inspecting and testing is performed on a regular basis.

It is recommended that you should use your CalCard weekly, with the results being recorded to ensure you have continuing accurate results. However, even though the Calcard has been highly recommended by electrical bodies, it will only confirm resistances in respect of low ohms reading testing and insulation resistance testing, therefore, full calibration tests will still need to be conducted annually.

Prize Draw Winner

Many thanks to everyone who took time to complete the survey. All participants were automatically entered into a free prize draw to win a CalCard worth £30 and one lucky winner was picked at random and has today been presented with his prize.
