Calibration evaluation After the calibration, the measuring instrument automatically evaluates
the current status of the calibration. The evaluation appears on the dis-
play and in the calibration record.
Determining the
cell constant
For this calibration procedure, the Measuring cell setting must be set to
cal in the measuring menu. Proceed as follows to determine the cell
constant:
