6.1.3.3. Recalibration/adjustment
The CO sensor can be recalibrated and adjusted.
For recalibration/adjustment, Testo recommends using calibration
adapter 0554 1205 or sending the instrument off to Testo Customer
Service.
If obviously unrealistic measured values are displayed, the
sensors should be checked (calibrated) and, if required,
adjusted.
Adjustments made with low gas concentrations can lead to
accuracy deviations in the upper measuring ranges.
