  • Page 24: Selecting Mode Of Operation

    The KT-9 has four modes of operation: – In this mode, measurements are activated by the special pin located at the top of the KT-9. This permits easier operation and achieves much higher accuracy when used for samples with irregular surfaces. This unique simple mode of operation auto- matically finds the zero-reference level after the reading has been taken.
  • Page 25 – In this special sub-mode of the N or C modes, the KT-9 continuously samples at a rate of 3 times per second. The unit also emits an audio tone that is directly proportional to the measured susceptibility. This mode may also be used for core logging with optional digital recording, as required.
  • Page 26 You will pass through the C: menu in this step. To select Scan mode The scan mode can only be activated when the KT-9 is set to the or C modes, i.e. the display should show either of the...

  • Page 27: Taking Measurements

    Taking measurements The KT-9 remembers the last mode of operation that was set. Therefore, for everyday use when the unit is turned on, it is ready to go. Depending upon what mode you have selected for opera- tion, there are slight variations in the procedures to obtain pre- cise and accurate true susceptibility readings.
  • Page 28 Taking measurements in Figure 4 on p. 14 Figure 5 KT-9 measuring modes Data Units – The KT-9 unit of measurement is in SI Units rang- ing from 0.01x10 to 999x10 , with a sensitivity of 0.01x10 Units.
