Introduction
1.1 General Information
The KT-10 v2 is an advanced hand-held magnetic susceptibility meter. The KT-10 v2
was developed as a joint venture between Terraplus Inc., a geophysical instrument
supplier located in Richmond Hill, Ontario (Canada), and Georadis S.R.O., a Czech
Republic based design and manufacturing company.
The KT-10 v2 is best utilized for obtaining accurate and precise measurements from
outcrops, drill cores and rock samples. The KT-10 v2 is capable of measuring uneven
rock surfaces and is well suited for automated drill-core logging with a digitally recorded
scanning mode.
With its leading edge technology, the KT-10 v2 offers high sensitivity, higher operational
comfort and excellent communication capabilities.
IMPORTANT: Your KT-10 v2 meter is calibrated at the factory and a periodic
calibration is not required.
1.2 Operating Principle and Theory
1.2.1 Theory
Magnetic susceptibility is defined as the degree to which a substance can be magnetized.
In mathematical terms, it is the ratio kof the intensity of the magnetization Ito the
magnetic field Hthat is responsible for the magnetization, i.e.
kH = I
7

From Ampere’s law, it is known that a current (i.e. a moving electrical charge) generates
a magnetic field. The inverse corollary to this is that a magnetic field can also influence a
moving electrical charge. Thus, an oscillating EM field will be influenced to varying
degrees by a magnetically susceptible material.
Conductivity is an intrinsic property of a microscopic volume of material. Apparent
conductivity is a volume average of a heterogeneous half-space except that the averaging is
not mathematical but dependent on each instrument. Only when the earth is a homogenous
half-space is the apparent conductivity the same as the true conductivity. The main advantage
of the electromagnetic conductivity method is that contact with the sample is not required. If
the conductive material is moved near to the measurement coil, new elementary electric
circuits are created. The sample will then behave like small secondary coils and influence the
magnetic flux through the measurement coil caused by mutual inductance. Naturally, this
leads to a change in the frequency. In general, the amplitude of the voltage signal decreases if
the conductivity increases and vice versa. Our method is based on the analysis of this change.
1.2.2 Operating principle
The KT-10 v2 utilizes a 10 kHz LC oscillator with an inductive coil to measure the magnetic
susceptibility and conductivity. Magnetic susceptibility is calculated from the frequency
difference between the sample and free air measurements, while conductivity is calculated
from the difference in amplitude between the two. It also takes into account geometric
corrections to determine the true susceptibility. The frequency of the oscillator is extremely
sensitive to temperature deviations. Any temperature instability is propagated in frequency
deviations and has a direct impact on maximum sensitivity. To minimize these effects, the
KT-10 v2 takes multiple measurements in free air before measuring the sample, and then
multiple free air measurements are taken afterwards. Then using a sophisticated algorithm,
the negative impact of temperature shift is minimized.
The sequence required to obtain a measurement is:
Step 1: The frequency and amplitude of the oscillator is determined in free
air.
Step 2: The oscillator frequency and amplitude is then measured when the
coil is placed on a rock sample, drill core, or outcrop.
Step 3: The frequency and amplitude of the oscillator is then measured
again, in free air, and then the results are displayed.

2.2 Features
The KT-10 v2 has many features that make it stand out in the crowd of available hand
held magnetic susceptibility & conductivity meters, and they are as follows:
Multiple Configuration Capability (optional)*
The KT-10 v2 can be upgraded to include conductivity measurements. With this upgrade
it can be configured as a simultaneous magnetic susceptibility/conductivity meter, a
magnetic susceptibility meter, or a conductivity meter.
Android Application for Real Time Profiling (optional)*
The optional GeoVision software can be used to display real time scanner profile on
Android platform operated smart phones. The large display of the smart phone will show
real time graphical output while scanning and can be used as a data browser to display
field measurements/records in the KT-10 v2 memory. The keypad of the smart phone can
be used to enter additional text notes to the current data or any previously stored data on
the KT-10 v2.
True Susceptibility and Conductivity
The KT-10 v2 uses automated correcting routines to display true susceptibility and
volume conductivity.
Uneven Samples
The KT-10 v2 is offered with a PIN for rough surface measurements. When measuring
field samples or outcrops with the PIN, and when the meter is kept parallel to the surface,
it provides a reading with increased accuracy. It also automatically corrects and displays
the true magnetic susceptibility and conductivity.
Fast Scanning
The KT-10 v2 scans up to 20 readings per second; increasing the amount of information
that user can obtain per location or sample.
Please note: 4 readings per second are stored on the KT-10 v2; 5 readings are averaged
together for each of the 4 readings per second.
10

Depth Correlation
Before starting the measurement routine, the user can now enter information such as
borehole ID, box ID and the number of rows in a box, along with the start depth, end
depth and depth interval. The user will have the option to choose between imperial or
metric as their desired unit of measurement. In the Scanner mode, depth intervals can be
recorded with the push of a button while scanning a core. All readings between depth
intervals are interpolated.
Variable Audio
When used in the Scanner Mode, the KT-10 v2 meter’s loudspeaker allows the operator
to monitor the variation in the Magnetic Susceptibility and Conductivity measurements
with a variable audio tone, which reflects the relative intensity of the reading. In the
combined mode, Susceptibility & Conductivity, the variable audio is active for the
primary reading. For example, in Cond+Sucs mode the audio will reflect the intensity of
the Conductivity measurements. The voice recorder allows the recording and replaying
of voice messages through the loudspeaker as well.
Data Storage
The KT-10 v2 can store up to 4000 measurements with two minutes of comments per
reading, to its internal non-volatile memory. Average readings and standard deviation are
also stored. The operator can record comments associated to specific readings through the
KT-10 v2 digital voice recorder.
Data Averaging
Stored results of the measurement are automatically added in an averaging buffer. The
average value is displayed on the LCD along with standard deviation. The operator can
erase the buffer and control how many results will be averaged together.
USB Data Transfer
The KT-10 v2 uses USB communication standards as the default mode of
communication. It allows fast data transfer of measured values and digital voice streams
from the unit to any Windows PC. The USB connection can be also used for firmware
upgrades and device parameter settings.
11

Bluetooth Connectivity
The KT-10 v2 comes standard with Bluetooth capabilities. When the KT-10 v2 is paired
to an external Bluetooth enabled GPS, the user can store the GPS coordinates in the KT-
10 v2’s memory along with the readings. Bluetooth can also be used to download
readings from the unit along with the voice streams to a computer. Alternately, one can
also pair the KT-10 v2 to an Android running smart phone to obtain Real Time Scanner
Profile.
Rain and Dust Proof
The KT-10 v2 meets IP65 standards; therefore it is protected against dust and provides
additional protection in rainy or high humidity conditions.
Large LCD Display
A high contrast LCD is utilized for the display of both the magnetic susceptibility and
conductivity readings and serves as the interface for operating the instrument. Together
with two buttons and graphical menus, operators can interactively navigate between the
different functions. On screen notification icons allows the operator to monitor the
battery status, Bluetooth connectivity, GPS support and more.
Power
Power saving techniques and use of low consumption components allow for the use of
high speed communication standards (USB, Bluetooth) and supports the large LCD
display. The meter is powered by 2 AA type batteries. The user can use any brand of
rechargeable or non-rechargeable battery. The unit does not contain an internal battery
charger. Therefore, rechargeable batteries must be charged outside the KT-10 v2 in a
suitable battery charger provided or similar.
Storage / Transportation
The KT-10 v2 is delivered in small pouch/case with a foam insert. The pouch can be
mounted on a belt and comfortably carried on the waist. A set of spare batteries and PINs
can be also placed in the pouch for storage. Even though the KT-10 v2 has been
designed to be a rugged instrument, it still can be damaged by severe impacts. Also,
please note that the KT-10 v2 is only water resistant, not water proof. Consequently, total
immersion in water or long exposure in heavy rain is not advisable for this instrument.
