Turtle Tough: Total Suspend Solids Sensor Manual 3.2 | Multi-Point Calibration In situations where increased levels of accuracy are needed, a multi-point calibration can be performed. The method to perform this calibration is: 1) Connect the sensor to a PC and set up Modbus Poll (as explained above) 2) Enter 2-point calibration mode by writing 2 to address 27 OR enter 4-point calibration mode by writing 3 to address 27.
Turtle Tough: Total Suspend Solids Sensor Manual Chapter 4. Maintenance To get the most accurate measurement results the sensor must undergo regular maintenance including sensor cleaning and inspection for damage. 4.1 | Sensor Cleaning Two lenses on the sensor need to be cleaned. Please perform regular cleaning and maintenance according to the actual use to ensure the accuracy of the measurement.

Turtle Tough: Total Suspend Solids Sensor Manual when powered incorrectly or improperly installed. Sensors containing internal electronic boards undergo additional quality checks prior to shipment to ensure that components are 100% operational upon delivery. Ground loop and 3rd party hardware problems (including but not limited to power supplies) may also cause blown electronics or damage to the sensor components and as such faulty installations are not covered by warranty.
5.3 | Shelf-Life Warranty The standard shelf life for a Turtle Tough sensor is one year from the date of shipment. Sensors stored longer than this period may still be functional but are no longer under warranty. Sensors should be stored in a cool, dry location with the sensor tip (where the pH/ORP element is located) oriented toward the ground.
