buttons, adjust the
setpoint
Confirm with "enter"
Wait until the device detects a stable
value
Then the device returns to normal measurement mode or, if applicable, returns an error
message. The resulting cell constant can be viewed in the menu under "CELL rAng" and in
the calibration history.
Error messages of the automatic calibration:

11 Automatic calibration of the cell constant
In addition to the direct input of the cell constant (see below) through the menu ("CELL
FACt"), the cell constant can also be automatically determined (please define CELL rAnG in
the menu first):
