Temperature Compensation
The displayed conductivity value is automatically compensated to the nominal value at the reference tem-
perature 25 °C using the sample temperature measured. The commonly used linear correction equation is
used:
Conductivity at

=
Conductivity at T

where
T

is the sample temperature in °C.

High Color and Turbidity Warning
The SP-710B has extra channels to measure sample turbidity and color to automatically compensate sam-
ple color and turbidity interference. If sample turbidity and color values determined are too high, a PTSA
measurement warning will be displayed. In such a case, the user should filter the sample for PTSA mea-
surement.

Fluorescein Measurement
Follow the steps below to measure Fluorescein:
1. Rinse the main module sample cell three times with the sample. Fill the sample cell with the sample.
2. Power on the SP-710B by pressing
. Allow 5–10 seconds for the SP-710B to stabilize.
3. Press
Measure
(
) as needed to highlight
Fluorescein
in the selection menu.
4. Press
to launch the
FLUORESCEIN MEASUREMENT
screen (Figure 7).
