If you have a PAT Tester, you should think about having it calibrated at least every 12 months, to ensure it is giving accurate results. After all, you're using the machine to determine whether your appliances are safe - you need to be able to rely on your tester!
Yotari, in conjunction with PAT Testing Expert and First Stop Safety can offer a high quality calibration check - checking the accuracy of your machine against results traceable back to the National Physics Laboratory.
Getting your machine calibrated is a simple process - download the Calibration Form here
When you're ready, contact First Stop Safety by fax or phone - their details are on the form.
They will arrange to collect the tester from you, or you can arrange to send it to them. Once it's been calibrated, they will contact you to arrange to return it to you. The whole process takes a few days, but if you need your machine back in a hurry, they will give you an accurate timescale when you speak to them.
We have used various calibration services in the past (and heard many horror stories) but we recommend First Stop Safety without hesitation. If you use a cheaper service, be aware that the check may not be 100% reliable, and may even 'pass' your tester when it's not giving accurate results.
Current prices charged by First Stop Safety are listed on the form.
