This section is also used
to input additional field
information if desired
Review and Process the recorded information
1. Review the Electrode Resistance and make the
necessary corrections to the Electrode distance with
respect to the ground distance
2. Ensure that the magnetic sensor were detected and if
necessary, make corrections to the Magnetic Sensor
types and serial numbers
3. View Recording Details, see the next page
4. Process the recorded data after review of information,

Review that the following levels are
within valid limits for quality control:
1. Battery
2. Temperature
3. GPS Timing Card Verify
4. Channels Details
If saturation is not close to 0%,
review the channel configuration
(see pages 4,5), the gain might
be too high and/or there is
artificial noise on your site

Verify that there was not warning display

Process Data
Setting up the processing parameters:
Click Process Button
1. Verify that the channels and references selected are the desired
2. Select the desired length of the recording to be processed by
decreasing the time at the beginning and ending of the recording
3. Enable the electric power grid filter that corresponds to the site (50Hz,
60Hz or None)
4. Click the Process button
5. A live display of the resistivity curve will appear after a few seconds
