5. Operation

5.1 Basic Measurement

To perform a basic measurement:

1. Ensure the correct probe is connected and calibrated.
2. Turn on the meter.
3. Press the Mode button to select the desired measurement mode (pH, Conductivity, ORP, etc.).
4. Immerse the probe into the sample solution.
5. Wait for the reading to stabilize. The auto-read function will sense and lock the measurement endpoint.
6. Press MEAS to freeze or release the measured value.

5.2 Calibration

Regular calibration is crucial for accurate measurements. The Bante 902P supports 1 to 5 points calibration with automatic buffer recognition.

1. Prepare the required standard buffer solutions (USA, NIST, DIN for pH; specific standards for conductivity).
2. Press CAL to enter calibration mode.
3. Follow the on-screen prompts to immerse the electrode in the specified buffer solutions.
4. The meter will automatically recognize the buffer and calibrate.
5. Repeat for all desired calibration points.
6. Press ENTER to confirm and save the calibration.

5.3 Data Management

The meter can store up to 500 data sets and communicate with a PC.

• Press M+ to store the current reading.
• Press MR to retrieve stored data.
• Connect the meter to a PC using the USB cable.
• Use the provided communication software to transfer data, record measurements at predefined intervals, and export to Excel files.

6. Maintenance

• Electrode Care: Always rinse electrodes with distilled or deionized water after each use. Store pH electrodes in appropriate storage solution, not dry.
• Cleaning: Wipe the meter's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure continuous operation.
• Storage: When not in use for extended periods, remove batteries and store the meter and probes in the carrying case in a cool, dry place.
