Calibration method

Refer to Table 1

Automatic zero calibration

(Turbidity, color, free residual chlorine)
Calibration method: Filtered water sample
Calibration Start method: Calibration starts with an internal timer and Modbus^®communication
Calibration period: 1 to 9999 hours (arbitrary setting)
Calibration time: 20 minutes

Automatic drainage

Start method: Drainage starts with an internal timer and Modbus^®communication
Drainage period: 1 to 9999 hours (arbitrary setting)
Drain count: 1 to 9 times (arbitrary setting)
Drain time: 9 to 45 minutes

Cleaning method

Turbidity, color: Continuous cleaning of cell window with wiper
Free residual chlorine: Continuous cleaning with beads

Sample water conditions

Temperature: 0 to 40℃ (should not be frozen)
Pressure: 0.1 to 0.75 MPa
Conductivity: 100 μS/cm or more
Amount introduced into the analysis section (flow rate): 80 to 100 mL/min
・When test-running, be sure to flush the instruments thoroughly before passing water through them.
・Be sure to provide a bypass for the piping leading to the instrument.
・If there is a risk of the sample water freezing, take measures by using insulation and heat retention device.
・Water samples measured with this device cannot be used for distribution.
・To keep the flow rate stable, avoid sudden fluctuations in water pressure.
