5.3 Calibration
The MAC 080 has a self-optimizing calibration algorithm able to handle several calibration
points in order to give maximum measuring precision in difficult applications. However, a single
point calibration is usually preferred.
After a calibration has been carried out, make it a habit to look at the calibration curve in the
sensor information screen to make sure it represents a smooth line without any sharp bends.
• Leave the instrument turned on for about 30 minutes prior to calibration so that the sensor
and electronics can stabilize.
• Please check that the correct unit is selected for the application. In the sensor menu, select
Settings > Unit
