1 INTRODUCTION
The pocket susceptibility meter KM-7 is designed for quick field measurements of
magnetic susceptibility of outcropping rocks, drill cores and larger pieces of rocks. The use of
KM-7 is especially advantageous for selecting of suitable specimens for further precise
laboratory studies of magnetic properties.
The KM-7 is designed for one-hand operation. A leather case can be worn on a waist-
belt.
1.1 Operation principles
The fundamental part of the instrument is an LC oscillator of 10 kHz, the inductivity of
which is embodied by a measuring coil situated at the active face of the instrument, the black
head. The susceptibility measurement is performed in three steps.
The frequency of the oscillator is measured with the coil at a distance at least 30cm
from the rock (initial measurement, AIR1), then with the coil applied to the rock surface
(SAMPLE) and again with the coils at a distance at least 30cm to achieve good sensitivity.
From the difference of the frequencies the susceptibility is computed and then displayed.

2 OPERATION
2.1 Power Supply
KM-7 is powered by two batteries (alcaline) or accumulators, type AAA. The battery
compartment is located at the bottom part of the instrument, the polarity of batteries is shown
at the picture at the back side.
2.2 Turning On/Off
Press the Enter button to turn the KM-7 on. The KM-7 introduction screen is displayed,
see chapter 2.6.1.
Press the Escape button for approximately 3 seconds to turn the KM-7 off. The
instrument is automatically turned off after ca 40 seconds of inactivity. If the KM-7 is
connected to a PC via USB/Bluetooth, or connection to Bluetooth GPS is active, the
automatic turn off is disabled.
2.3 Control buttons
The KM-7 magnetic susceptibility meter is controlled by four buttons, Enter, Escape,
Up and Down.
Figure 2-1 KM-7
The Enter button is used for entering a sub menu, enabling editable items and activating
action items. The Escape button located at the opposite side terminates an action on editable
items without change or returns to the upper menu when pressed in a sub menu. The Up and
Down buttons are used to browse among menu items and select values from predefined
editable items, e.g. enable or disable backlight.

5
To see which item in the KM-7 menu is selected, arrow at the left side of the display is
used. The position of the arrow points to the selected menu item.
2.4 Items setting
The KM-7 setting items are of two types: items to select one of predefined choices and
items to set a numerical value. All items with choices display their actual values. After Enter
button is pressed for the selected item, the original value is inverted and with the Up and
Down buttons the desired value can be selected. In case of the numerical values, the value is
incremented or decremented respectively. After the Enter button is pressed, the selected value
is stored to the KM-7 memory and a respective action is taken, e.g. Bluetooth is turned on. If
Escape button is pressed, the value of the item is not changed and the control is returned back
to the menu.
The arrow located at the left side of a menu shows which item is selected.
2.5 Status icons
The KM-7 uses several status icons. They can be seen on the right side of the display in
any of the KM-7 menus and sub-menus.
The battery icon displays battery status.
Figure 2-2 KM-7 battery status icon
The other icons that can be seen on the KM-7 screen show a connection status. If the
KM-7 is connected to PC via USB cable, the USB icon appears.
Figure 2-3 USB connection icon
If the Bluetooth is enabled, the Bluetooth icon appears, see Figure 2-4. Note only one
connection icon can be visible at a time, because only one type of connection can be
established at a time. The USB connection has the higher priority than the Bluetooth
connection. When the Bluetooth connection is active and the USB cable is connected, the
connection type is changed to the USB connection.
Figure 2-4 Bluetooth connection icon
If the KM-7 connection to the PC is established (via USB or Bluetooth) and is active
(program KMdata), the PC icon appears.

In the case that Bluetooth GPS is enabled in Setup>BT ON and connection type is set to
GPS in Setup>BT menu>BT GPS, the GPS satellite icon appears when valid GPS data are
received, see Figure 2-6. In the case of single mode measurement with GPS enabled, this icon
appears after measurement, indicating that the actual measurement can be saved with the
actual and valid GPS data. Otherwise valid and actual GPS data has not been received from
GPS and measurement can not be saved with GPS data.

The second item in main menu is a link to the Memory menu, see chapter 2.6.4.
The third item is a link to the Setup menu, see chapter 2.6.5.
2.6.3 Measuring
The first item is Measure. On the right side of this item, an actually selected
measurement sensor is indicated (FLAT, PIN, CORE). This can be changed in the Setup
menu.
If Enter button is pressed when Measure selected, the user is requested to set one of
three modes of measurement:
1. Single –one measurement.
2. Scan –data are continually measured and results are displayed on the display only.
3. Scan remote –continual measurement, where the measured data are transferred to
the PC via USB or Bluetooth and processed by the program KMdata.
After the mode of measurement is set, the initial measurement can be done (at least
30cm distance from a sample or other materials). This is indicated on the display by “AIR1”
notice. In the case the Escape button is pressed, the main menu is displayed. If button Enter is
pressed, the initial measurement is taken and “SAMPLE”is displayed to indicate that the
initial measurement is done, and the KM-7 can be put to the sample to measure its
susceptibility. In the case the Escape button is pressed, the “AIR1”notice is displayed again.
The selected sensor is indicated at the bottom line.
SAMPLE
Sensor: PIN
Figure 2-9 Ready for measuring
If the “SAMPLE”indicator is displayed and Enter button is pressed, the susceptibility
of the sample is measured. During the time of collecting signal, which takes ca 0.5s, the icon
Mis displayed at the left upper corner of the display and the beep is heard. Please do not
move the instrument when the Mis on. To complete the measurement, the third step is
required, again the measurement at least 30cm far from solid materials, see the notice
“AIR2”. The timeout between the steps is 10s. If the measurement is not completed by the
time, the notice “AIR1” is displayed and the kappameter is ready to start anew. If the set of
the three measurements are completed properly, the value of susceptibility is displayed, see
Figure 2-10. Mem indicator (left side) specifies location in the Memory menu, Loc indicator
(middle bottom) shows the user predefined location number. This can be set in the Memory
menu. Now, if the Enter button is pressed, the measured value is stored to the KM-7 memory,
if the Escape button is pressed, the measurement is lost. A new measurement can be taken.

Sensor setting2.6.5.1
The first item of the Setup menu allows to select a sensor (PIN, FLAT, CORE), for
editing see the chapter 2.4Chyba! Nenalezen zdroj odkazů..
The value measured with the KM-7 depends on the size and shape of the sample.
The instrument KM-7 is calibrated for the idealized case in which the pick-up coil is
attached to an absolutely smooth plane confining a half-space filled with magnetically
homogeneous and isotropic medium. Then the displayed value of the susceptibility is the true
value. (The true value of susceptibility is computed in the microprocessor from the measured,
so called apparent, susceptibility.) If the sample is smooth enough and large enough, the
sensor FLAT may be used. It is not recommended to measure samples less than 50 mm thick,
with a surface smaller than the KM-7 face (60 mm).
However, often only rough surfaces of rocks are available for measuring. In that case, it
is recommended to use PIN option. The small (0.5cm long) pin screwed to the head of the
KM-7 defines the position of the pick-up coil –the distance from the surface, which may give
more precise results. The surface of the rock should be paralel to the surface at the head of the
instrument. The instrument is calibrated for the option. The measured value does not require
any corrections. Sensitivity of the measurement is limited to 1x10-5 SI units.
In measuring on outcrops it is necessary to consider the degree of weathering of the
surface which affects the results considerably. The weathering effect can hardly be evaluated;
therefore measuring on unweathered though less smooth surface is preferred.
In measuring drill cores, it is recommended to attach the pick-up coil to the side rather
than to the head of the core, since the core side is an almost perfectly smooth cylindrical
surface, while the head is uneven and usually of a small diameter. It is essential that the
cylinder measured be longer than 100 mm. The values measured on a cylindrical surface are
again the true values because the instrument is calibrated for the various diameters. When
selecting CORE, the user is requested to set the diameter of the core.
System menu2.6.5.2
Various settings of KM-7 are available:
BACKLIGHT ON
TIME/DATE
INFO
Figure 2-14 System menu
The first item allows to disable or enable the backlight of the display. If the backlight is
enabled, it is automatically turned off after ca 10 seconds of user’s inactivity. It is turned on
by pressing a button. The backlight ON increases the power consumption ca three times.
Setting the current time and date in the instrument can be done here (time/date) or by
a PC in the KMdata program (Synchronize time). The values of hours and minutes are
incremented and decremented by pressing Up and Down buttons. Enter button moves the
control to the next item. To set the date, similar way of editing is used. To exit the time and
date setting without changes, pres Escape button. Seconds are set to zero after all time and
date values are set and confirmed by the last Enter.
Info displays manufacturer, device name, serial number and firmware version.

GPS DATA
Figure 2-15 BT MENU
The first item allows searching for Bluetooth devices. All devices in the range are
searched, and the user must select the Bluetooth GPS (most likely the GPS will be in its
name) from a list of found devices. The search process displays maximum four devices. If
SEARCH is selected and Enter button is pressed, the KM-7 begins searching for devices in the
range, and the progress is indicated by dots. This action takes ca 40 seconds and can not be
canceled.
If no device is found, BT device not found is displayed and Escape button must be
pressed to get back to the BT menu. Otherwise, list of found devices and their names is
displayed. The user can select the desired Bluetooth GPS by Up and Down buttons and press
the Enter button to use the selected device as the default GPS data source or press the Escape
button to end without changes.
The second item of the BT menu allows selection of the connection:
1. PC connection –the PC connection to the KM-7 and communication with KMdata
is established
2. GPS –the KM-7 connection to the default Bluetooth GPS
The third item displays current GPS data, see Figure 2-12. KM-7 must be set up for
connection to a Bluetooth GPS, and the Bluetooth GPS must be turned on.
