5. Funtzionamendu-prozedura
5.1 Measuring Water Activity
- Sakatu Boterea key to switch on the meter. The gauge will enter auto mode, automatically initiating the water activity test.
- Jarri zure sample s garbi batean sartuample plate. Ensure the sample is representative and fills the plate adequately without overflowing.
- Carefully cover the sensor of the meter onto the sample plate, ensuring a good seal.
- Allow approximately 5 minutes for the reading to stabilize. Once stable, the water activity value will be displayed on the LCD.
- After testing, press and hold the Boterea key for approximately 3 seconds to turn off the meter.
- Garbitu sample plate thoroughly after each use to prevent cross-contamination and ensure accurate future readings.

6. Reading Correction (Calibration)
If it becomes necessary to correct the reading value, follow these steps:
- Eduki sakatuta Boterea tekla gutxi gorabehera 7 segundoz.
- Release the key when the signal 'Cor' appears on the display. A decimal number with two places, representing the current correction value, will be shown.
- Open the battery cover on the back of the meter. Below the battery slot, you will find two small holes.
- Using a small, hard, non-conductive tool (e.g., a small screwdriver or toothpick), gently touch the key inside the left hole to increase the correction value.
- Gently touch the key inside the right hole to decrease the correction value. Adjust the value as needed.
- Sakatu Boterea key again to confirm the new correction value. The measured reading will update, and the calibration is complete.

7. Mantentzea
7.1 Garbiketa
- Garbitu beti sample plate immediately after each use to prevent residue buildup, which can affect measurement accuracy.
- Erabili biguna, damp cloth to wipe the exterior of the meter. Do not use abrasive cleaners or solvents.
- Ensure no liquids enter the sensor area or battery compartment.
7.2 Biltegiratzea
- When not in use, store the meter in its carrying case to protect it from dust and physical damage.
- Gorde leku fresko eta lehor batean, eguzki-argitik eta muturreko tenperaturatik urrun.
- Kendu bateriak gailua denbora luzez erabiliko ez bada, isuriak saihesteko.
8. Arazoak
If you encounter issues with your VTS-160A Water Activity Meter, consider the following:
- Potentziarik gabe: Egiaztatu bateriak behar bezala instalatuta dauden eta nahikoa karga duten. Beharrezkoa bada, ordezkatu bateriak.
- Irakurketa okerrak: Ziurtatu sample plate is clean and the sensor is properly seated on the sample. Perform a reading correction as described in Section 6. Verify that the operating conditions (temperature, humidity) are within the specified range.
- Slow Readings: Ziurtatu sample is properly prepared and the environment is stable.
