4. Орнотуу жана Батареяны орнотуу
The HI98331 meter comes with batteries pre-installed. If replacement is necessary:
- Батарея уясынын капкагын эсептегичтин арткы жагында табыңыз.
- Twist the cover counter-clockwise to remove it.
- Remove the old CR2 battery and insert a new one, observing polarity.
- Батарея уясынын капкагын ордуна коюңуз жана аны бекитүү үчүн саат жебеси боюнча буруңуз.
Ensure the battery compartment is sealed tightly to prevent moisture ingress.
5. Иштөө нускамалары
Follow these steps for accurate bulk EC measurement using your HI98331 Direct Soil EC Meter:
- Prepare the Testing Location: Select the specific area in the soil where you wish to take a measurement.
- Пробду тазалоо: Rinse the testing probe thoroughly with deionized water. Gently wipe it dry with a clean, soft cloth.
- Moisten the Soil: Ensure the soil in the testing area is adequately moist. Dry soil will not yield accurate readings.
- Create an Insertion Hole: Use a ruler or an auger to create a pilot hole in the soil. This helps maintain consistent testing depth and prevents damage to the probe.
- Insert the Tester: Carefully insert the HI98331 soil conductivity tester directly into the prepared hole in the soil. Ensure good contact between the probe and the soil.
- Өлчөө алуу: Wait for the reading on the digital display to stabilize. Record the displayed EC value.

6. Калибрлөө
For optimal accuracy, regular calibration of your HI98331 is recommended. Refer to the specific calibration instructions provided in the full product manual or on the manufacturer's website. Typically, calibration involves using standard EC solutions.
7. Техникалык тейлөө жана сактоо
- Зонд тазалоо: After each use, rinse the probe with deionized water to remove any soil residue. Do not use abrasive materials.
- Сактагыч: Store the meter in a clean, dry environment. Ensure the probe is clean and dry before storage.
- Батареянын иштөө мөөнөтү: Дисплейде батарейка аз индикатору пайда болгондо батарейкаларды алмаштырыңыз.
8. Кыйынчылыктарды
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| No display/Meter does not turn on | Өлгөн батареялар же туура эмес орнотуу. | Батареянын полярдуулугун текшерүү; батареяларды алмаштыруу. |
| Так эмес окуулар | Dirty probe, dry soil, or meter out of calibration. | Clean probe, moisten soil, perform calibration. |
| Туруксуз окуулар | Poor contact with soil, air bubbles, or damaged probe. | Re-insert probe firmly, ensure soil is moist, inspect probe for damage. |
