7.8.2. Settings Interface Clicking on "Settings Interface" tab opens a sub-menu for Alarm Parameters and Senser Parameters. Figure. 22 –Setting Interface Alarm Parameters Setting Users can set the upper and lower alarm limits. Click "Alarm Parameters" to enter the alarm parameter settings. When the measured sensor value is lower than the set lower limit (the XX lower limit alarm) or when the measured value is higher than the set upper limit (the XX upper limit alarm), the corresponding sensor alarm will be displayed on the real-time monitoring screen. - Page 21 Sensor Parameters - Smoothing Factor Description & Adjustment In "Sensor Parameters” within the “Settings Interface" field of the "Parameter" menu, users can set the smoothing coefficient for the sensor. Usually the oxidant concentration (e.g., free chlorine) is a very small signal, which is easily subject to external interference.
- Page 22 Pyxis Lab uses the term “T90” when the measured value of the sensor reaches 90% of the true value to describe the speed of the sensor response in seconds. The default smoothing factor of ST-765P-DCL Series sensor is 0.002 (T90≈4 minutes). The available setting range of the smoothing factor is 0.001 to 0.9. The following table outlines the comparison between the smoothing factor and T90 for the ST-765P-DCL Series sensor and should be used if considering an adjustment to the smoothing factor settings.
