Hi, it is recommended to calibrate the instrument once every 2-3 months. I hope this helps

Do you need to calibrate the instrument just after first opening ??

Thank you for your query, it shouldn’t need calibrating straight out of the box, however, when you have started using the unit it’s best to recalibrate on a regular basis, the more it’s recalibrated (depending on the amount of times it’s being used), the more accurate the results will be. Once a week or once a month etc. We hope that helps!

Hi, my reference oil stated on the label is 2.8% TPM, when I calibrate, the result is around 4.5%. The instrument is new. Could you please advise why the deviation the result and the reference is quite far?

Hello, when you get the 4.5% result on the oil tester, you should then adjust the 270 to the % of the reference oil by pressing the arrows on the 270. This link here shows how to calibrate the 270: www.testo.com/en-UK/services/video-trainings-testo-270 Hope that helps!
