1、 接線錯誤，會導致傳感器工作不正常！ Wrong wiring may cause abnormal sensor running!
2、螺紋口及以上部位，必須與被測溶液完全隔離。 Thread mouth and the parts above must be completely isolated with the tested solutions.
3、為確保儀器測量準確，建議傳感器周圍保留20mm空間，傳感器圓環要浸入溶液中，避免其他物質靠近感應區域。 In order to guarantee accurate instrument measurement, 20mm space is suggested to keep near the sensor. The sensor ring shall be immersed into the solution avoiding other materials near the induction area.
4、安裝時感應區域圓孔朝上或傾斜朝上,可以避免偶爾的空氣氣泡。將傳感器懸浮在溶液中防止接觸容器（如僅簡單地隨意將它放入容器中會導致測量誤差），且測量過程中應保持探頭的靜止；The round hole at induction area shall be laid upwards or leaned upwards during installation, which may avoid casual air bubble. Suspend the sensor in the solution to prevent touching the container (measuring error may appear if put it into the container at will), and keep the probe still during the measuring process.
5、 測試鹽度最好工作溫度-2-35℃。The most proper working temperature to test salinity is -2-35℃.
6、因溫度補償內置，所以測試鹽度和溫度時，需要靜止一段時間待溫度穩定后，再讀取數值。 Values of salinity and temperature shall be read after keeping still for a while and temperature becomes stable due to built-in temperature compensation.
7、安裝時，不要通過旋轉扭動傳感器的“環型”末端來緊固連接，這會導致傳感器殼體破碎。Do not rotate or twist the sensor ring end to fasten connection during the installation process, which may cause the sensor shell to break.
8、不要將探頭穿過任何帶有交流或直流電的管道。電信號可能會干擾傳感器信號。Do not pass the probe through any pipe with AC or DC power supply. Electric signal may possibly interfere sensor signal.
