6.1.2 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 25
°
C =
Conductivity at T
measured
1 + 0 . 02( T
measured
– 25)
(1)
where T
measured
is the sample temperature in °C.
6.1.3 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.
6.2 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).
