    There are different versions of the Model 3007i - the Model 3007i and the Model 3007Bi. The difference is the detector’s boron moderation. The Model 3007Bi has more boron modera- tion, which helps with the over-response of the 5 keV region.
  • Page 20 It is located to the left of the detector connector. If a headphone jack is not in use, the Model 3007i may optionally be provided with an RS232 serial output for connection to PC or other electronic device.

    2.4. INSTRUMENT DIAGNOSTICS Time and date are necessary when the instrument is configured for datalogging as each log record is time/date stamped. Additionally, time and date are crucial when the instrument is configured to report that a new calibration is due. 2.4.2 Definitions If the instrument displays the definitions reset message, this indicates that the memory which maintains the detector definitions has been reset.

To connect an instrument to the computer, please connect one end of the USB cable to the instrument first, and then the other end to the computer.

  • Page 79: Advanced Features

    DVANCED EATURES 7.1 Dead Time Correction All pulse counting detectors have a “dead time” in which the detector is unable to register another event. In relatively low fields this is not an issue. However, as the field strength approaches the high end of the detector’s range, dead time causes the pulse rate to become non-linear with respect to the real radiation field.
