15 A TYPICAL SURVEY (USING GRID BATCH MEMORY)
This section leads you step-by-step through taking measurements, saving cover and half-cell
readings in batches and producing a report. The instructions are for a model TH; users of a model
SH will be limited to linear batches only.
1. Mark out your survey area (in this example a 14 x 14 grid).
2. Fit the search head to your Covermeter, switch on and set
Instrument Mode to Cover.
3. Create a new 14 x 14 grid batch for cover and name it
'001'.
4. Measure the depth of cover over the entire survey area
and record the cover measurements in the batch created
at step 3 (press Enter [ ] to store a reading in the batch).
5. Fit the half-cell probe and cables and then set Instrument
Mode to Halfcell.
6. Create another 14 x 14 grid batch, this time for half-cell.
Give the batch the same name as the cover batch (in this
example, '001').
7. Measure the half-cell potential over the entire survey area and record the measurements in the
batch created at step 6 (again, press Enter [ ] to store a reading in the batch).
You now have two batches in your Covermeter, each of the same name ('001') - one containing
cover measurements, the other containing half-cell potential measurements.
8. Connect your Covermeter to a PC and download the two batches using CoverMaster software
- see "Transferring readings to a computer" on page 52.
9. You can now produce a 'Topographic combined' or 'Topographic overlay' report which shows
cover and half-cell potential on one easy-to-read report.
