Memory Function; Saving Measurements Into Memory - AEMC 6470-b User Manual

The instrument has a total of 512 memory locations. Each of these locations is
defined by an object number (OBJ) from 01 to 99 and by a TEST number from 01
to 99.
For 3- and 4-pole earth measurements, the sweep mode (SWEEP) can record
several measurement results at the same memory location, with the frequency as
third addressing criterion.
During soil potential or resistivity measurements (Wenner or Schlumberger meth-
ods), several measurement results are recorded at the same memory location,
with the distance between electrodes as the third addressing criterion.
For earth coupling measurements (EARTH COUPLING 1, 2, 3, 4), the four mea-
surements provide the third addressing criterion for the same memory location.
None of the other measurements has an additional addressing criterion, so each
occupies only one memory address.
Since each measurement is dated, you must set the date and time of the device
before any storage in memory (see § 4.2).

7.1 Saving Measurements into Memory

Measurement results can be saved by performing the following:
Press the MEM button. The tester will automatically suggest the next free
•
memory location (
Press the MEM button a second time to save to the OBJ/TEST location.
•
• If you decide not to save your results, press DISPLAY to exit MEM mode.
• To change the OBJ and TEST location, use the ► and ▲▼ buttons.
NOTE: If a memory location is already occupied, the message
played. Pressing the MEM button will overwrite the measurement record.
For soil resistivity and potential measurements, if several measurements are made
with different distances (d), you can store them under the same OBJ:TEST num-
ber, with the distance being the third criterion.
It will be possible to overwrite values already stored with new ones having the
same distance d, or even to add new results having other values for the distance d
provided that all of the other measurement parameters are identical.
