ES adjust (empty sensor adjust)
Press this control to confirm that the sensor is presently empty.
You will be asked whether you want to perform a hard or soft empty sensor
adjustment.
Soft adjustment:
You simply inform the device that the sensor is empty or that there is an empty
measuring cup in the sensor.
Hard adjustment:
A hard adjustment is recommended if measuring results seem inaccurate or
distorted after relatively long periods of measuring. Again, you inform the de-
vice that the sensor is empty. At the same time, however, some internal pa-
rameters are adjusted so that material wear on the sensor or measuring cup
is taken into account. A new absolute empty reference point is set.
To perform an empty sensor adjustment, you need to be logged on with appro-
priate rights.
Reference standard
This function is designed to carry out a technical check of the device on the basis
of a reference body which can be acquired as an optional extra.
For more information, see page 57.
To execute this function, you must be logged onto the software with the appro-
priate rights.
