DI water for the zero step as soon as it is available. 2. Power on the SP-380 by pressing . Allow 5–10 seconds for the SP-380 to stabilize. 3. The unit is actively reading and displaying PTSA. The values will be very low if DI water is used; con- ductivity value is not critical but PTSA value should be near zero. -
Page 12: Fluorescein Calibration
7.2 Fluorescein Calibration The SP-380 is designed to provide a flexible calibration procedure. The user can start with the two-point (DI water and 50 ppb fluorescein) calibration and progressively add a three- and four-point calibration with 250 ppb and 500 ppb fluorescein, respectively. This allows the user to choose a procedure based on the need of measurement accuracy and the target fluorescein range. - Page 13 Success” message will appear (Figure 11). Otherwise, a warning message is displayed. 18. Calibration is now complete. Press Exit ( ) to return to Fluorescein measurement mode. Figure 7. Figure 8. Figure 9.
