This section is used for inputting
the parameters and instrument
details that will be used for the
recording Additional information
1. Check that the Receiver type is MTU-5C
2. Select the Schedule
1.1. Manual or Automatic Start
1.2. Or for a specific schedule use, Single Shot,
Daily or Weekly and click Add Schedule to
define the time and date
3. Channels Settings
4. Define the Receiver Settings
○ Sampling Mode
○ Sampling Rate
5. Live tool (see the Networking Settings manual)
6. Configuration Layout
To use the magnetic sensor data from a different recording or
use a remote reference, all recordings must have a matching
Sampling Mode and Sampling Rates. Otherwise, EMpower will
not allow to process data using borrowed channels or remote
reference

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
6. Network connector
In the field, it is often most efficient to connect the
components to the receiver following the order on the right

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. After reviewing the information, Process the data
(see next page)
Field QC
The warning icon indicates that something might be wrong with
the recording, review the recording information and make
necessary changes
This section can also be used to input
additional field information if desired

Process Data
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 for QC purposes

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
