Magnetic Susceptibility Device

Select File | Open Device Manager.

Select a Magnetic Susceptibility device from the list, or add a new device if one is not already configured.
New devices can be added by clicking on the Add button and selecting an option:

Devices can be removed by highlighting the device and clicking on the Trash Can.
Input the details of your Magnetic Susceptibility device:

Details

Display

Enter the name of the device as it will appear in the Device Manager window.

Communication

Geobank Mobile can connect to a KT-10 Magnetic Susceptibility device via a USB or a Bluetooth connection.

To setup a Bluetooth pairing with a chosen KT-10 device in Geobank Mobile:

Set the Communication Type to Bluetooth.
Set the Bluetooth Device to the {Paired Device Name}, for example KT-10-8157 in the example below.

If the Bluetooth pairing is broken while the device reading screen is open, Geobank Mobile will attempt to reconnect for 15 seconds. If a connection cannot be established, Geobank Mobile will then close the device reading screen and return any reading values in the data entry form.

If a Bluetooth connection has been configured in the Device Manager but for some reason the user connects to the device via USB, the Bluetooth connection will still be active. However, if the Bluetooth connection is not found, Geobank Mobile will fall back on the USB connection.

Logging

Select the check box if you want to log messages sent to and from the device.

Click on the ellipsis button to navigate to the location of the Log filename.

KT-10 V2 Settings

Ensure that you set this value to match the read value you have set on the KT-10 version 2 device itself. If there is a mismatch, a zero reading will be reported in the mobile application:

Read value	Description
Mag Sus	The degree to which a substance can be magnetized is termed Magnetic Susceptibility. An electrical current generates a magnetic field. Conversely, a magnetic field will have an influence on a moving electrical charge. A device which emits an oscillating electro magnetic field will therefore be influenced by the presence of a magnetically susceptible material. In mathematical terms, magnetic susceptibility, k, is defined as: kH = I where k is the ratio of the intensity of the magnetization I to the magnetic field H.
Conductivity	Electromagnetic conductivity is calculated from the difference in amplitude between a sample and free air measurements. When conductive material is moved near to the measurement coil, elementary electric circuits are created and the material has an influence on the magnetic flux through the coil. The greater the conductivity of the material, the lower the amplitude of the voltage signal. Resistivity is the reciprocal of Conductivity.

Conversely, a magnetic field will have an influence on a moving electrical charge.

where k is the ratio of the intensity of the magnetization I to the magnetic field H.

Conductivity

Electromagnetic conductivity is calculated from the difference in amplitude between a sample and free air measurements. When conductive material is moved near to the measurement coil, elementary electric circuits are created and the material has an influence on the magnetic flux through the coil. The greater the conductivity of the material, the lower the amplitude of the voltage signal.

Resistivity is the reciprocal of Conductivity.
