3. Setup (Sensor Installation)

Follow these steps to properly install your new PCTS 50 replacement sensor:

1. Ensure the Oakton Waterproof PCTSTestr 50 is turned off.
2. Carefully unscrew the old sensor from the meter body by turning it counter-clockwise.
3. Remove the protective cap from the new PCTS 50 sensor.
4. Screw the new PCTS 50 sensor firmly onto the meter body by turning it clockwise until it is hand-tight. Do not overtighten.
5. Rinse the sensor tip with distilled water before initial use.
6. Proceed to calibration before taking any measurements.

4. Operating Instructions

4.1. Calibration

• Regular calibration is crucial for accurate readings. Refer to your Oakton Waterproof PCTSTestr 50 manual for detailed calibration procedures for pH, conductivity, TDS, and salinity.
• Always use fresh, appropriate calibration solutions.
• Rinse the sensor with distilled water between calibration points and before taking measurements.

4.2. Taking Measurements

1. Turn on your Oakton Waterproof PCTSTestr 50.
2. Immerse the sensor tip fully into the sample solution. Ensure there are no air bubbles trapped around the sensor.
3. Allow sufficient time for the reading to stabilize on the meter display.
4. Record the measurement once stable.
5. Rinse the sensor with distilled water after each measurement.

5. Maintenance

5.1. Cleaning

• After each use, rinse the sensor thoroughly with distilled or deionized water.
• If deposits are visible, gently clean the sensor tip with a soft brush or cotton swab. For stubborn deposits, consult the Oakton Waterproof PCTSTestr 50 manual for specific cleaning solutions.
• Avoid abrasive materials that could damage the sensor membrane.

5.2. Storage

• Always store the sensor with its protective cap filled with appropriate storage solution (e.g., pH 4 buffer or electrode storage solution). Never store dry.
• Ensure the protective cap is securely fastened to prevent the sensor from drying out.
• Store the meter and sensor in a cool, dry place, away from direct sunlight and extreme temperatures.

6. Troubleshooting

If you encounter issues with your sensor, review the following common problems and solutions:

• Unstable Readings:
  • Ensure the sensor is fully immersed and free of air bubbles.
  • Check for proper calibration. Recalibrate if necessary.
  • Clean the sensor tip thoroughly.
  • Verify the sample temperature is within the sensor's operating range.
• No Reading or Error Message:
  • Check the connection between the sensor and the meter. Ensure it is secure.
  • Verify the sensor is not visibly damaged.
  • Ensure the meter's batteries are charged.
• Inaccurate Readings:
  • Recalibrate the sensor using fresh, unexpired calibration solutions.
  • Clean the sensor thoroughly to remove any contaminants.
  • Consider the age of the sensor; electrodes have a finite lifespan and may need replacement if they no longer hold calibration reliably.
