Maintenance

Cleaning the Electrode

After each use, rinse the electrode with distilled water to remove any residue. Do not use tap water or other cleaning agents, as this may affect accuracy.

Storage

Always replace the protective cap after use. Store the meter in a cool, dry place away from direct sunlight and extreme temperatures. If the device will not be used for an extended period, it is recommended to remove the battery.

Troubleshooting

• No Display/Device Not Turning On: Check if the battery is installed correctly and has sufficient charge. Replace the battery if necessary.
• Inaccurate Readings: Ensure the electrode is clean. Recalibrate the device if readings are consistently off (refer to calibration section if applicable, though no specific calibration steps are provided in product data).
• Reading Fluctuates: Ensure the electrode is fully immersed and there are no air bubbles. Allow sufficient time for the reading to stabilize.
