Automatic NIR sensor calibration
Fig. 184
The NIR sensor performs automatic calibration if the following conditions are fulfilled:
• At least 10 hours of sensor operation have elapsed since the last calibration of the NIR
sensor.
• The maintenance release switch is switched on or the field mode release switch is switched
off, see page 134.
• The setpoint engine rotational speed is 800 rpm or higher (fixed value, cannot be changed).
The calibration is cancelled once the "NIR sensor active" condition is met again.
Possible status displays
An impermissible measured value or a measured value outside the
measuring range was determined.
The NIR sensor is not active, or one/several conditions are not fulfilled.
