7.5. Calibrating/adjusting the instrument
You can check the accuracy of your instrument by carrying out a
comparative measurement with the Testo reference oil (calibrating).
If there is too great a difference between the reading and the
reference value, future instrument readings can be adjusted to the
reference value (adjusting).
