Annual Calibration

● We will contact you 4 weeks prior to when your tester is due for calibration  
● We will issue you with an RMA number  
● You need to securely package your tester and include the RMA number  
● We will arrange collection of your tester  
● The tester will be calibrated within 5 working days and returned directly to you.  
Note – if required we can provide a loan unit, however we aim to turn the testing round so  
quickly, usually within a couple of days, so you shouldn’t need one.  
Please note as part of the calibration service we will also ensure that your tester is updated with  
the latest firmware – should you not want to update the firmware at this point, please make our  
technical team aware of this when booking in your calibration update.
