Preface Dear customer Thank you for your Yosemite Technologies’ instrumen. Reading the entire manual before use is highly recommended for operation and maintenance the instrument and out of unnecessary trouble. Please observe the operating procedures and precautions in this manual.
Overview Yosemitech Optical dissolved oxygen sensor measures dissolved oxygen using the principle of oxygen dynamic luminescence quenching technique. When blue light excites sensor film, the sensing film emits red light. The phase difference between the blue excitation and returned red emission is measured, and the result is used to calculate DO concentration. :...
Installation Part List Item Number Note Y504-A Sensor Cable protective cover Rubber protective Cap Before use 1) Take off the protect cap: Please take off the protect cap of Optical dissolved oxygen sensor , before installation and keep them properly for future use.Meanwhile, tighten the protective cover.
Calibration PC tool name: SmartPC(DO).exe. (Please scan the QR code on the right to download the application software). Note: If custom development is needed, please contact Yosemitech Customer Service. Calibration Solution Preparation Preparation for zero oxygen environment: take 200mL distilled water and pour it into the prepared beaker, then add anhydrous sodium sulfite, add and stir at the same time, until anhydrous sodium sulfite is insoluble and solid crystallization occurs, then the standard solution can be regarded as close to 0 oxygen.
(See modBus documentation) Yosemitech Sensor has also developed pc-based calibration software for Y504 dissolved oxygen sensor. You only need to connect the probe to the calibration software through the computer interface, and you can easily complete the calibration of the sensor according to the software prompts.
Maintenance Maintenance Schedule Unlike traditional electrical chemical sensors, optical DO sensors require low maintenance. There are no need for frequent solution filling and calibrations. Maintenance task Frequency Sensor cleaning Every 30 days Sensor and sensor cap inspection Every 30 days Sensor cap replacement Every one year Calibration(if required of agency)...
head is dry for a long time, the measurement results will drift, and it needs to be soaked in water for 48 hours before continuing to work. Attention Protect the inner surface of the fluorescent cap from sun exposure. Do not touch the fluorescent film with your hands. Avoid applying any mechanical stress (pressure, scratch, etc.) directly to the fluorescent film during use.
Trouble Shooting Table 5-1 lists the symptoms, possible causes, and recommended solutions for common problems encountered with the Y560-A sensor. If your symptom is not listed, or if none of the solutions solves your problem, please contact us. Table 5-1 Troubleshooting ERROR POSSIBLE CAUSE SOLUTION...
