5. Operating Instructions

Follow these steps for accurate bulk EC measurement using your HI98331 Direct Soil EC Meter:

1. Prepare the Testing Location: Select the specific area in the soil where you wish to take a measurement.
2. Clean the Probe: Rinse the testing probe thoroughly with deionized water. Gently wipe it dry with a clean, soft cloth.
3. Moisten the Soil: Ensure the soil in the testing area is adequately moist. Dry soil will not yield accurate readings.
4. 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.
5. 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.
6. Take Measurement: Wait for the reading on the digital display to stabilize. Record the displayed EC value.
