3.10 FlashRES collects 62k data/hr, is all of this data useful?
A partial amount of the 62k data may not be useful, but it is difficult to deduce which part of the collected data isn't useful. As the diagram below shows, all three curves are important. Any underground anomaly will affect the shape of these curves. Thus, before assessing the geological data, it is difficult to deduce which part is unimportant.
This is the reason FlashRES resistivity meter records the whole three curves for each current pair, not just a few data points. Users can choose the right data after data collection. For the flat parts of these three curves, the user may not need too many data points. Very low voltage data is normally represented by these 'flat' parts of the curve. For these parts, a user only needs a few control data points; this is one of our considerations when removing some data.
