Thermostat

Operating temperature of the conductivity

measuring cell.
Selection:

25, 30, 35, 40, 45 °C, off

The Thermostat function operates only if the ambient tem-

perature is at least 5 °C lower than the operating tempera-

ture. Normally, it takes approx. 30 to 60 minutes for the op-

erating temperature to be reached with a temperature sta-

bility of

±

0.01 °C.

Flow

correction

Correction factor for allowing for the de-
viation between the displayed flow rate

and the actual flow rate of the high-
pressure pump.
Range:

0.9 ... 1.09

The

correction factor is determined by

measuring the actual flow rate using a

measuring cylinder as follows:

Cell

constant

Cell constant of the conductivity measur-

ing cell for correct display of the absolute
conductivity. Enter the value printed on
the detector block in this field.

Range

:

0.1 ... 99.9 /cm

In order to determine the c

ell constant

yourself, you must pump a calibration so-
