4. Konfigurazzjoni u Installazzjoni tal-Batterija
The HI98331 meter comes with batteries pre-installed. If replacement is necessary:
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-miter.
- Twist the cover counter-clockwise to remove it.
- Remove the old CR2 battery and insert a new one, observing polarity.
- Replace the battery compartment cover and twist clockwise to secure it.
Ensure the battery compartment is sealed tightly to prevent moisture ingress.
5. Istruzzjonijiet Operattivi
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.
- Naddaf is-Sonda: 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.
- Ħu Kejl: Wait for the reading on the digital display to stabilize. Record the displayed EC value.

6. Kalibrazzjoni
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. Manutenzjoni u Ħażna
- Tindif tas-Sonda: After each use, rinse the probe with deionized water to remove any soil residue. Do not use abrasive materials.
- Ħażna: Store the meter in a clean, dry environment. Ensure the probe is clean and dry before storage.
- Ħajja tal-batterija: Ibdel il-batteriji meta jidher l-indikatur ta' batterija baxxa fuq id-displej.
8 Issolvi l-problemi
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| No display/Meter does not turn on | Batteriji mejta jew installazzjoni ħażina tal-batterija. | Iċċekkja l-polarità tal-batterija; ibdel il-batteriji. |
| Qari mhux eżatt | Dirty probe, dry soil, or meter out of calibration. | Clean probe, moisten soil, perform calibration. |
| Qari żbaljat | Poor contact with soil, air bubbles, or damaged probe. | Re-insert probe firmly, ensure soil is moist, inspect probe for damage. |
