0 to 150 FNU (or 0 to 150 NTU); SC1000 Controller or other programmable
controller calculates turbidity compensation based on the PAH reading and
turbidity reading.
Note: The user must manually enter the turbidity compensation formula into the controller.
Refer to Figure 8 on page 15 for the formula.
Calibration standard measured
Factory calibration with Phenanthrene equivalent standards
Optional: 1-point or 2-point user calibration with the Phenanthrene equivalent
standards in the Calibration Kit.
As an alternative, the calibration slope and offset values can be changed
manually.
