Slope

The display screen for Entering the conductivity/temp Slope is shown.
The default value is displayed in bold type. Refer to the toroidal
conductivity Programming flow diagram to complete this function.
Ref Temp
8.5.8
The display screen for manually Entering the Reference temperature is
shown. The default value is displayed in bold type. Refer to the toroidal
conductivity Programming flow diagram to complete this function.
8.5.9

Filter

The display screen for entering the input filter value in seconds is shown.
The default value is displayed in bold type. Refer to the toroidal
conductivity Programming flow diagram to complete this function.
using the highest range (90 mS to 1500 mS) in very low conductivity
processes below 100 µS (conductance) might generate a high noise
value relative to the actual process value. In these cases, it is
recommended to increase the input filter setting above the default
value of 2 sec. to suppress the effect of noise.
8.5.10

Custom Setup

The display screens for creating custom curves for converting
conductivity to concentration is shown. Refer to the toroidal
conductivity Programming flow diagram to complete this function.
When the custom curve data entry is complete, press ENTER. The
display will confirm the determination of a custom curve fit to the
entered data by displaying this screen:
If the custom curve fit is not completed or is unsuccessful, the display will
read as follows and the screen will return to the beginning custom curve
screen.
