11.1 CAL mode (adjustment)

11.1.1 Adjustment
After a long period of usage or following the replacement of the dispensing unit, an adjustment may
be necessary to balance out differences in accuracy up to a maximum of ± 0.999 ml. The change from
the factory setting is shown in the display.
1. Calculating the adjustment value
The adjustment value is the deviation of the mean volume from the nominal volume (e.g., mean vol-
ume 50.024 ml, nominal volume 50 ml. Adjustment volume = 50.024 ml - 50.000 ml = 0.024 ml). For in-
formation on calculating the mean volume, see Checking the Volume (Calibration), p. 66.
