Action
ACTION operation is a function that allows you execute the following operations by using the
buttons on the LCD.
ACTION
AUTO WASHING
CHECK ALARM
MEAS.(ZERO)
MEAS.(SPAN)
DRAIN
SAMPLING
CHECKING
AUTO DRAIN
Use wiper of the turbidity/color cells to wash the turbidity/color cells.
Check automatically that the turbidity, color and the residual-chlorine sensor
display zero when measuring the zero-solution and that the conductivity sensor
(optional) drains the water in the cell and displays zero (zero opening). When
zeros are not shown, the analyzer-abnormality alarm is activated.
This function is used to check the cause of alarm (sensor or sample water)
when the alarm for abnormal concentration is activated when measuring sample
water.
Measures the zero calibration solution that filtered sample water and checks the
measured value of each sensor.
Measures the span calibration solution in the calibration solution tank and
checks the measured value of each sensor. You need to connect the calibration
solution tank to the calibration inlet of device.
Drains the water from the cell. Perform this when doing maintenance such as a
sensor exchange, or when stopping operation.
Obtains sample water from abnormal sample inlet. One a water sampling has
been performed, it can not be performed again the function is reset.
（See "5.6.3 Perform the SAMPLING RESET" (page 93).)
It is necessary to connect the container to obtain a water sampling to the inlet.
Repeat the drain sequence as specified in "AUTO DRAIN SETTING".
