Flow correction

Factor for correction of the difference between

displayed and actual flow rate of the high-

pressure pump.

Range:

0.9

...

1.09

The flow correction is determined by measure-

ment of the actual flow rate with the aid of a

measuring cylinder as follows:

Cell constant

Cell constant of the conductivity cell for correct

display of the absolute conductivity. Enter the

cell constant printed on the detector block into

this field.

Range:

0.1

...

1000 /cm

For a precise determination of the cell constant,

pump a calibration solution of known conduc-

tivity through the IC system, observe the dis-

played conductivity and change the cell con-

stant until the correct conductivity value is

displayed.

Possibility for changing the break times for in-

These values should only be changed after

consulting the Metrohm Service.
