In order to select the Custom Offset Mode, see Figure 25. If the room temperature differs
more than 2°C from 23°C (temperature of the factory calibration) or if you use a custom plate
adapter, non-included in the list reported in Table 1, Okolab recommends this working mode
recalibrating the chamber following the procedure reported in paragraph 12.
