Aspect MKC-A03 Operation

Placing the MKC-A03 on the docking station will automatically power on the instrument, perform a self-test, and calibrate the instrument.

If the instrument does not power on automatically, press and hold the center button to manually power on.

Green LED shows the docking station is supplying power to the instrument.

Instrument operation involves use of five buttons whose functions change with the mode.

Background collection starts automatically.

When background is complete, the unit will automatically enter “Search/dose rate” mode; graphs of gamma and neutron levels are displayed.

Place a marker (tape, pencil, etc.) on points exhibiting elevated radiation. There may be more than one point of interest.

The Identification display screen provides useful information while measurement is conducted.

Optimal identification measurements are obtained when the screen displays the message “Ok!”.

For high activity isotopes, the MKC-A03 screen will display the message “move away.” In this case, move the instrument farther away from the radioactive material until “Ok!” is displayed.

For relatively weak radioactive sources, the MKC A03 will display the message “move closer.” In this case, keep the instrument as close as possible to the location of interest and, if possible, continue the measurement for a longer time (see next step). Longer identification measurements result in a higher probability and accuracy of isotope identification.

When set identification time is complete (120 seconds) the display shows the isotopes found and each isotope category. The four possible isotope categories are: industrial, medical, naturally occurring radioactive material, and special.

If the message “Nuclides are not found…” is displayed, press button “C” to continue measurement.

Returning the instrument to the docking station will automatically recharge the batteries

Press and hold the central button for 2 to 3 seconds if necessary to power off instrument for storage or transport.
