III. Sensor Calibration

Accurate sensor calibration is crucial for ensuring reliable measurement data. The Partech 750w² Monitor supports calibration of suspended solids and dissolved oxygen sensors.

3.1 Suspended Solids Sensor Calibration

3.1.1 Zero Calibration

Zero calibration is the first step in the calibration process, used to eliminate baseline readings when no suspended solids are present.

  • Steps:
    1. Immerse the sensor in clean water, using a dark container to minimize ambient light interference.
    2. Enter the main menu, select Measurement Config, and then select Suspended Solids.
    3. Choose the Set Zero function, wait for the reading to stabilize, and press the OK key to complete zero calibration.

3.1.2 Set Measurement Range (Set Cal)

Setting the measurement range ensures accurate sensor measurements within the expected concentration range.

  • Steps:
    1. Determine the maximum expected concentration value for suspended solids based on your application.
    2. In the Measurement Config menu, select the Set Cal function.
    3. Use the arrow keys to adjust the measurement range to the maximum expected concentration value and press the OK key to confirm.

3.1.3 Take Sample for Calibration

When the exact value of the calibration solution is unknown, use the Take Sample function.

  • Steps:
    1. Immerse the sensor in a representative sample.
    2. In the Measurement Config menu, select the Take Sample function.
    3. Wait for calibration to complete; the instrument displays a calibration success message.

3.2 Dissolved Oxygen Sensor Calibration

3.2.1 100% Open Air Calibration

Dissolved oxygen sensor calibration is typically performed in open air to ensure accurate measurement of dissolved oxygen concentration in water.

  • Steps:
    1. Ensure the sensor is in a draft-free environment to avoid interference.
    2. Enter the main menu, select Measurement Config, and then select DO Saturation.
    3. Choose the Calibrate function, wait for the saturation percentage to reach approximately 90%, and press the OK key to complete calibration.

IV. Advanced Configuration and Features

In addition to basic measurement and calibration functions, the Partech 750w² Monitor offers numerous advanced configuration options and features to meet diverse user needs.
