    The DETECTOR button is used to select the active detector. The Model 3003i version has all the features of the Model 3003 plus the addition of an internal detector for tracking user exposure rate or dose, but both instruments will hereafter be referred to as “Model 3003”.
  • Page 16 It is located to the left of the detector connector. If a headphone jack is not in use, the Model 3003 may optionally be provided with a RS232 serial output for connection to PC or other electronic device.

  • Page 17: Getting Started

    Check individual item serial numbers and ensure calibration certificates match between instruments and de- tectors (if applicable). The Model 3003 serial number is located on a label on the front side of the unit.

    The instrument then displays the current revision level of each board installed in the system: main board, internal detector high-voltage board, and auxiliary communications board. Figure 2.2: Hardware Revision Levels A revision level of 0 indicates that the board is not installed or detected. Next, the instrument displays the firmware version. Ludlum Measurements, Inc.

TURNING THE INSTRUMENT ON Figure 2.3: Firmware Version Display The first character defines the firmware type, the second character defines the major version level, and the third character defines the revision level. The build version is not displayed. The instrument then displays the battery voltage. The low-battery indicator is only displayed to indicate that the value displayed is related to the battery voltage and not that the battery voltage is low.

    2.4. INSTRUMENT DIAGNOSTICS Time and date are necessary when the instrument is configured for data logging 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.

    2.7 Detector Failure Diagnostic Note that the Model 3003 has its own diagnostic tests to ensure that the detector is function- ing correctly. The Model 3003 can detect when the radiation detector is malfunctioning and will flash the display to indicate a fault.

    Figure 2.11: Detector Over Range (Display Will Flash) 2.7.4 Detector Overload As another diagnostic test, the Model 3003 monitors the HV supply’s detector current. A current overload threshold can be set via Setup Mode. (A setting of 0 disables this alarm.) In general, this alarm setting can be used to detect when there is some detector failure, a cable failure, or a possible high level of radiation.

    OFTWARE 6.1 Connecting to Software The Model 3003 software is sent with a standard two-meter cable. (A five-meter cable can be provided if requested. However, any cable longer than two meters may have issues with some USB hubs and computers, typically laptops.) 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 85: 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.
