For example, if you took several measurements at the same combination or skipped a, adjust worksheet accordingly. Make sure the resistivity values correspond to the four-electrode combinations (electrode distances from the origin in meters) they were taken on in the next four columns. Download data to laptop and paste them into ERM-data_in worksheet in first three columns (separate data from cell number and K0 indicators using Excel Data function “Text to Columns”). Then move AB electrodes to #1 and #7 and MN electrodes to #19 and #25 (detail instructions below).Īfter completing all measurements listed in Excel file for levels 1, 2 and 3 you will have 980 data points stored in LandMapper’s memory and about to reach a limit of the memory. Continue in the same way as for Levels 1 and 2, moving MN electrodes at one meter steps to the right (eighteen diagonal measurements marked by red numbers, starting with “57”. Connect AB electrodes to #0 and #6 nails. Increase dipole size one more time to AB=MN=6 m. Then move AB electrodes to #1 and #4 (detail instructions below). Continue in the same way as for Level 1, moving MN electrodes at one meter steps to the rights (eleven diagonal measurements marked by green numbers, starting with “29”. Connect AB electrodes to #0 and #3 nails. In order to go deeper, we will increase the size of dipole to AB=MN=3 m. Level 1 measurements cover approximately 2.5 meter depth. Twenty eight sets of six measurements complete Level 1 set of measurements. Therefore, after completing six moves of MN dipole, move AB dipole to electrodes #1 and #2 and repeat six measurements moving MN electrodes in the similar manner (six measurements marked “2” on the picture above). You should not exceed total length in any combination (from A to N electrode) to more than 7*a in order to keep good signal-to-noise ratio of the system. you can flip-flop M and N electrodes in dipole, this will not affect measurements. Note, that you can just move one alligator clip, from electrode #2 to #4, i.e. For the next measurement (marked by “1” diagonally) move MN electrodes to #3 and #4. Take first measurement of electrical resistivity with LandMapper. In the same way connect electrodes #2 and #3 to MN terminals of LandMapper using black wires. For the first measurement connect electrodes #0 and #1 with alligator clips on the red wires and push banana plugs on the AB terminals of LandMapper. Level 3 - AB=MN= 6 m (skipping some electrodes)Įlectrodes are numbered from left to right starting with “0”. Level 2 - AB=MN= 3 m (skipping some electrodes) Level 1 - AB=MN= 1 m (measure at each electrode) In this setup there will be three levels of the measurements, for different sizes of dipoles: We refer to size of dipoles (distance between AB or MN electrodes) as “a” and during measurement protocol we will move dipole MN farther to the right from dipole AB “n” times.

You will be making series of measurements with AB (current) electrodes planted at the beginning of the line and moving MN farther apart to reach deeper. Hammer electrodes (nails) in a straight line one meter apart. metal objects) of rectangular shape, for example as on the figure below. The method can help to pinpoint areas of very low resistivity (i.e. This protocol was tested by several groups of archeologists and is most suitable for detecting relatively large burial places and shallow caves.

This protocol is designed that whole set can be saved into LandMapper’s memory (stores 1000 data points), downloaded to PC, recalculated in Excel workbook and re-formatted for Interpretation of data in RES2DINV software (see DIY for demo version of software ). Different depths and resolutions are possible by modification of this basic protocol, per request we can develop custom protocols for you ( ). The profile can continue indefinitely to the right, as shown in Excel file. The detail description below covers step-by-step protocol to conduct dense (~0.5 m resolution) measurements down to ~14 m depth and 50 m long.

RES2DINV TUTORIAL MANUAL
The complete scheme of dipole-dipole manual protocol is provided as Excel workbook on USB drive to all our customers. You can also watch instructional videos on our YouTube Channel - LandviserLLC Principle of measurements with both sets is the same for both cable sets and is illustrated by figure below. We supply wires with banana-plug connections to LandMapper terminals on one end and alligator clips on the other end to connect with electrodes. Electrodes are simple metal spikes/nails and is sourced locally (are NOT provided by Landviser, LLC). Stationary set (~ 14 m depth) where electrodes are hammered on the soil surface along the straight line at one meter distance.
