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
M
is displayed at the left upper corner of the display and the beep is heard. Please do not
move the instrument when the
M
is 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.
