13. ANNUAL RE-CALIBRATION
Whilst the sensors have an expected life of more than two years in normal use it is
recommended that the analyser is re-calibrated at least annually. This is so that long
term drift on the sensors and electronics can be eliminated. Local regulation may
require more frequent re-calibration and users should check with appropriate
authorities to ensure they comply with relevant guidelines.
