Page 20: Calibration
Turbidity Calibration The LT-739 Series Ultra Low Turbidity Sensor is rigorously calibrated at the Pyxis Lab factory. If the sensor is kept clean, the user will not need to calibrate the sensor for one year of operation. However, the user may calibrate the sensor as desired. - Page 21 Figure. 17 Turbidity Calibration Screen When calibrating, click the corresponding "Low Cal""Mid Cal""High Cal", the standard solution value input box will pop up below, enter the standard solution value in the input box to start calibration Figure. 18 - Enter the standard solution value - 17 -...
- Page 22 Click "OK", if the calibration is successful, the dialog box will show "Calibration successful". *NOTE* Because there is no global standard for zero turbidity in the industry, Pyxis recommends 0.05 NTU as a target for Low-Point Calibration while using Bubble-Free DI Water.
- Page 23 High-Range Calibration using the FR-100 Flow Reservoir: If a high-range calibration is not required, the user does not need to perform a high-range calibration of the LT-739 series sensor. If a high calibration is required, proceed by rinsing the L-CAL vessel with deionized water and refill with known turbidity standard solution between 20NTU and 40NTU for high-range calibration (see page 21).
