4. Kalibrazioa

Regular calibration ensures the accuracy and reliability of your measurements. It is recommended to perform calibration at least once a day or if the instrument has been moved.

4.1. Weight Correction Procedure

1. Power on the instrument and allow it to preheat for at least 30 minutes to ensure thermal stability.
2. From the main menu on the touch screen, select the "Standard Weight CAL" (Calibration) option.
3. Ensure the display value is 0.0. If it is not, press the "Peel" button (often indicated by a '0' with an arrow) to tare the sensor.
4. Gently hang the provided calibration weight onto the scale hook using tweezers. Ensure the weight is stable and not shaking.
5. Wait for approximately 10-20 seconds for the reading to stabilize. The instrument will automatically prompt that the correction is complete.
6. Carefully remove the calibration weight. The display should return to 0.0, indicating successful calibration.

5.1. Preparing the Platinum Plate

The platinum plate must be thoroughly cleaned before each measurement to remove any contaminants that could affect accuracy. This process involves burning the plate in an alcohol flame.

1. Hold the platinum plate securely with tweezers.
2. Ignite the alcohol lamp.
3. Place the platinum plate in the flame of the alcohol lamp until it glows red. This process burns off any organic contaminants and moisture.
4. Allow the platinum plate to cool to room temperature (approximately 15 seconds) before use. Avoid touching the plate with bare hands after cleaning.

Video 3: This segment demonstrates the essential step of cleaning the platinum plate using an alcohol lamp, ensuring it is free from contaminants for accurate surface tension measurements.

5.2. Wilhelmy Plate Method Measurement

Follow these steps to perform a surface tension measurement using the Wilhelmy plate method:

1. Carefully place the cleaned platinum plate onto the instrument's hook.
2. Place your liquid sample in a clean petri dish or suitable container on the sampdutage. Ensure the sample volume is sufficient for the plate to immerse without touching the bottom.
3. Close the glass door of the instrument to prevent air currents and external disturbances from affecting the measurement.
4. Press the "Peel" button on the touch screen to tare the sensor, setting the initial reading to 0.0.
5. Press the "Start Test" button. The sampdutage will slowly rise, bringing the liquid surface into contact with the platinum plate.
6. The instrument will automatically detect contact between the platinum plate and the liquid surface. The machine sensor will then sense the surface tension in real-time.
7. The surface tension value will be displayed in real-time on the screen, often accompanied by a dynamic curve.
8. Once the data stabilizes, press the "Stop Test" button to conclude the measurement.
