Occasional negatives can occur in many conditions, and are more prevalent in dry soils. If both shallow and deep values are negative, that point is eliminated from the data file. If only one is negative, the point is recorded. Typically, if less than 5% of the values are negative or missing, there is an adequate amount of data remaining to generate an acceptable map.
- If dry soil is the issue, lower implement deeper into the soil; additional weight may be required.
- Lower speed if field is rough, allowing the implement to maintain better contact with soil
- Use test load and test box/ohmmeter to test electronics, continuity, and electrode isolation (see manual)
