Start by connecting:
1. Ground electrode
2. Electrodes to channel E1(Ex) (N+, S-) and
channel E2(Ey) (E+, W-)
3. Magnetic sensors to channels H1(Hx), H2(Hy)
and H3(Hz)
4. GPS antenna
5. 12V DC Power Source

Review and Process the recorded information
1. Review the Electrode Resistance values and
make the necessary corrections
○ Electrode Distance (m) to GND
○ E-Azimuth
○ External Filter
2. Ensure that the magnetic sensors were
detected and make the necessary corrections
○ Serial #
○ Polarity
○ H1-H-3 Azimuth
3. View Recording Details (see page 14)
4. Process the recorded data after the reviewed
the information (see next page)

1. Click the Process button
○ Verify that the channels and references
selected are the desired ones
2. Define the time period by entering a start
and end date/time
3. Enable the electric power grid filter
that corresponds to the frequency carried
by the power lines in the survey region
(50Hz, 60Hz or None)
4. Click the Process button
5. A live display of the resistivity curve will
appear after a few seconds
*This resistivity curve is not saved. It is purely

Review that the following levels are
within valid limits for quality
control:
1. Battery Voltage
2. Internal Temperature
3. Number of Satellites
4. Saturated Frames
○If saturation is not close to
~0%, review the channel
configuration (see pages 4 - 6),
the channel gain might be too
high and/or there is artificial
noise on your site
5. Time Series Level
