Y505-A Maintenance
1.Maintenance Schedule
Unlike traditional electrical chemical sensors, optical DO sensors require low maintenance.
There are no need for frequent solution filling and calibrations.
www.yosemitech.com
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
）
Calibration based on required schedule
Note
：
above schedule is only for reference, customers should make on their own judgment
based on their applications. Yosemite Technologies’ sensor cap may be used longer than
one year, we recommend to replace the sensor cap per year to ensure performance.
2.Routine Maintenance
DO Probe:
•
Inspect all sensor connectors for corrosion and replace sensors if necessary.
•
Inspect sensor o-rings and replace if necessary
•
After prolonged storage, calibration of the sensor is required.
•
After use, rinse the sensor body with tap water, dry it, and put on storage cap. Keep DO
sensor storage cap wet to moisturize DO membrane surface.
•
DO NOT DRYOUT DO SENSOR CAP!
•
Inspect the sensor for scratches or cracks, if any are present , replacement of sensor cap
may be needed.
Cable:
Cable’s minimum bending radius is 15mm. The wires inside the cable may break if it is under
long term stressed condition.
3.Sensor Cap care and Storage
Sensor cap storage
：
if the senor do not in use, store the sensor in its storage cup. Store the
sensor cap in water saturated air. If sensor cap has been dried out, please submerge the
sensor cap in warm (about 40 -50
⁰ C) water for 48 hours
。
Do not expose sensor cap under direct sunlight, keep surface clean, dirty or scratch will
cause inaccurate reading.
If DO membrane surface is dirty, try to rinse the surface with tap water first. If necessary,
please gently wipe the surface with lens cleaning tissues that has been moistened with clean
water. Do not use organic solvents to clean the sensor cap.
