Installation Detector installation method Use the supplied U-bolts to attach the 2-inch (50 A) pipes. If the turbidity detector is installed at a height of approx. 1 m, it will make it much easier to operate. A special stand (optional) is used to temporarily hold a removed cleaner.
Installation Flow A through 20 A are suitable for the piping to the turbidity detector. In the turbidity detector, be sure to run samples upward from below. Install a valve (V-2) for flow rate adjustment at the outlet of the turbidity detector. If samples are supplied in-line and this valve is throttled, measurements can be made while pressure is maintained.
Page 30
Installation Method of using the overflow tank If an overflow tank is used for the SS measurement of drain water, lead a flow of samples to the overflow tank installed above the turbidity detector, and then lead a flow of the samples filtered with a rough mesh to the turbidity detector.
Page 31
Installation In-line measuring method For measurement of tap water, etc., measuring inline can prevent the formation of air bubbles, and obtain even lower turbidity. To maintain sample pressure, throttle the valve on the outlet side. The flow rate decreases, but water pressure increases, thus suppressing the formation of air bubbles.
Installation Sampling method Type of sampling pumps For a sampling pump, be sure to select a centrifugal pump that can reduce the formation of rust. A pump in which exhalation pressure rises rapidly when the outlet of the pump is shut for maintenance purposes is not suitable for use.
Operation Operation Preparation for operation When this equipment is used for the first time, perform the following. Wiring check Check the installation status of sensors. Initial settings (the selection of working curve, settings for transmission signals, and settings for operating conditions of relay contacts) Calibration (zero calibration and span calibration) (Calibration after resetting is not needed required because calibration information is stored on the sensor side and is called up to the screen under energized conditions.

Information for accurate measurements Information for accurate measurements This chapter provides information on maintenance aimed at ensuring accuracy, such as calibration methods. Zero calibration Cal mode Zero calibration is an operation adjusting the value of clean water to zero. The following calibration method is recommended, depending on the degree of turbidity. If low turbidity water (such as tap water or swimming pool water) is being measured, the turbidity resulting from air bubbles and matter adhering to the wall surfaces may make it difficult to accumulate zero water and calibrate it.
Information for accurate measurements 6. After zero calibration is completed, return to the Meas. mode. 7. Press the ESC key to return to the Meas. mode. Blinking Numeric value In the Zero Calibration mode, a negative measured value is also displayed. Selecting turbidity standard substances Select turbidity standard substances from among Kaolin, Formazin, and Polystyrene Latex.
Information for accurate measurements Checking the zero calibration data On the Calibration Data Check screen, checks can be made of the amount of transmitted light for zero calibration and the number of days elapsed since the date of the last zero calibration. A check of the amount of transmitted light makes a comparison with the initial amount of transmitted light.
Moreover, an optional span calibration bottle for span calibration is also available from HORIBA Advanced Techno. If a span calibration bottle is used, signals as a substitute for a standard solution can be obtained simply by shaking and mixing the span calibration bottle strongly.
Page 61
Information for accurate measurements Span calibration procedure Pouring a standard liquid 1. Close the sample valve, and open the drain valve to discharge samples from the turbidity detector. 2. Detach the cleaner and wash the cell. 3. Wash the inside of the cell of the turbidity detector adequately. 4.
Information for accurate measurements Maintenance Cleaning the detector Remove the cleaner, and clean the cell section of the detector with a soft brush, etc. When the detector becomes soiled, errors caused by flaking dirt become larger at the time of zero calibration.
Information for accurate measurements Replacing the wiper rubber of the cleaner. The wiper of the cleaner is made of silicone rubber. If the number of times of cleaning operations increases, a wiper will gradually change shape. Replace the wiper. As a rule, wipers should be replaced once a year for an automatic cleaner. WARNING Unexpected operation of the unit may result in damage to the unit or an injury.
Information for accurate measurements Replacing the motor of the cleaner As a rule, replace the drive motor of an automatic cleaner once every three years. WARNING Unexpected operation of the unit may result in damage to the unit or an injury. Be sure to turn OFF the power when replacing consumables.
