MODEL 1057
6.4.9 Slope
The display screen for Entering the conductivity/temp
Slope is shown. The default value is displayed in bold
type. Refer to the contacting conductivity Programming
flow diagram to complete this function.
6.4.10 Reference Temp
The display screen for manually entering the Reference
temperature is shown. The default value is displayed in
bold type. Refer to the contacting conductivity
Programming flow diagram to complete this function.
6.4.11 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 contacting conductivity
Programming flow diagram to complete this function.
6.4.12 Custom Setup
The display screens for creating a custom curve for
converting conductivity to concentration is shown.
Refer to the contacting 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.
6.4.13 Cal Factor
Upon initial installation and power up, if 4-electrode
was selected for the sensor type in the Quick Start
menus, the user enters a Cell Constant and a "Cal
Factor" using the instrument keypad. The cell constant
is needed to convert measured conductance to
conductivity as displayed on the analyzer screen. The
"Cal Factor" entry is needed increase the accuracy of
the live conductivity readings, especially at low conduc-
tivity readings below 20uS/cm. Both the Cell Constant
and the "Cal Factor" are printed on the tag attached to
the 4-electrode sensor/cable.
