Stability time and level for automatic zero calibration

When calibrating the zero point of turbidity, it is necessary to determine the zero point at the
lowest value of turbidity, while supplying water for which fine particles have been removed to
the extreme through the sensor. Even when the inside of the cell is adequately cleaned and
zero water is replaced frequently, there is still the influence of contamination and bubbles
when the sensor is filled with zero water. As the best way to perform calibration, first clean the
cell and piping adequately, then check that the measured value has decreased by gently
supplying water, which has been filtered through an ultra filter, to the cell. Then, perform zero
calibration when the measured value has reached the lowest value. At this point, in order to
prevent air bubbles from forming, adjust the flow rate by closing the valve on the outlet side,
instead of adjusting it on the inlet side of the sample water.
Although it is not difficult for us to determine the zero point, it is not possible for computers to
make the same judgment as we do. The following describes the judgment method for zero
calibration programmed in this equipment. Read through the description and specify the
optimum parameters in accordance with the on-site conditions.

Parameters for judgment of zero calibration

Stability level: A value used for comparison with the difference between the instantaneous
value of turbidity and average value (resolution: 0.01)

Stability time: Stability level duration time for which the zero calibration conditions are met

Software concept for automatic zero calibration

When the system enters the automatic zero calibration mode, the valve is switched and zero
water is supplied through the sensor. When the time allowed for the water line switching has
elapsed, the instantaneous value of turbidity and moving average value are calculated, and
the difference between these values is obtained. If the difference is continuously below the
value specified for the stability level during the stability time, zero calibration is performed at
this point. If the difference between the instantaneous value and average value exceeds the
stability level, the stability time will be reset.
If the zero calibration conditions are not met within 20 minutes, which is the maximum time for
automatic calibration, an E-43 error will be output. Even when this error occurs, the
measurement continues from the latest calibration operation.

Parameter

Tendency

Increasing the stability level

Less strict criteria are set and zero calibration is performed with a high turbidity.

Shortening the stability time
Decreasing the stability level

Stricter criteria are set and zero calibration may not be performed within the time.

Lengthening the stability time
