The probe to ensure full contact with the soil, and compaction, to ensure the accuracy of data.2. Soil meter only tests soil, not suitable for dry flour, small stones, organic wood chips, liquid particles and so on.3. In order to improve the accuracy of the test results, please take the average value of multi point test during the test.4. When using, pay attention to the test point do not touch the stone, do not exert too much force, otherwise it will easily hurt the electrode. Not suitable for long time in the soil, easy to oxidize.5. After measurement, clean the soil particles on the surface of the probe with gauze in time to keep the probe dry.
