What to do How to do it Keys to press Display readout
The continuously displayed CAL symbol indicates that the factory default setting has been changed.
By entering a new adjustment value, this will be added automatically to the already existing adjustment
value.
The already adjusted instrument shows a new deviation of the mean volume
from the nominal volume, for example, 0.017 ml.
(For calculating the mean volume, see page 46).
