This section describes how to calibrate the turbidity sensor against a user-prepared
standard as a two-point calibration with deionized water, against a 20 NTU user-prepared
standard as a single point calibration, and against a grab sample using a reference
turbidmeter.
To calibrate the turbidity sensor:
1. Press ENTER/MENU from the main screen to access the Calibration screen.
2. Select S1 Measurement or S2 Measurement and press ENTER/MENU.
3. Press INFO at any time to learn more about this procedure. When you press INFO, a
