Getting Started
Ensure the probe is properly connected and the sensor cap is maintained in a moist environment. Calibration is recommended before daily use for optimal accuracy. Refer to the manual for detailed calibration procedures for saturated oxygen and zero-oxygen points.
Measurement and Settings
The DO850 allows for various parameter settings, including dissolved oxygen units (mg/L or %), resolution, temperature units (°C or °F), auto-lock, auto-backlight, and auto power-off. Detailed instructions for accessing and modifying these settings are provided within the manual.
Probe Maintenance
Proper maintenance of the optical DO probe, particularly the sensor cap, is crucial for performance. Keep the sensor cap moist using the provided calibration sleeve and sponge. Avoid contamination and mechanical damage to the sensor cap.
Troubleshooting
The manual includes a troubleshooting section to address common issues such as calibration errors, inaccurate readings, and instrument power problems. Solutions are provided for each identified error.
