    DMC 3000 User's Guide 2.1 Use and Functionality The DMC 3000 is the compact, rugged and reliable dosimeter designed to detect a wide range of X-ray and gamma radiations. The large-format, backlit, high-contrast 8-digit LCD display provides clear dose and dose rate readings for deep dose equivalent Hp(10).

  • Page 6: Compatibility With Mirion Technologies Products

    DMC 3000 User's Guide 2.2 Compatibility with Mirion Technologies Products The DMC 3000 features two protocols, G3 and G2, that use the same communication medium, with an omni- directional, low-frequency (125 kHz) transceiver. The enhanced "G3" communication protocol to support additional features and attached measurement „...
  • Page 7 Future release: Added PRD module support. „ The DMC 3000 must be calibrated for Hp(0,07) gamma at the factory prior to initial use with the Hp(0,07) Module. Check the verification certificate to see the calibration in Hp(0,07) of your DMC 3000.

  • Page 11 An additional module, such as a telemetry device, Hp(0,07) beta, Hp(10) Neutron or PRD module can be atta- ched at the bottom of the DMC 3000 simply by removing the battery cover. All these add-on modules have their own parameters saved on non-volatile memory and modify the display configuration of the DMC 3000 when attached to it.

  • Page 12: Historical Data Function

    ‰ In order to date accurately all the data, the DMC 3000 is equipped with a Real Time Clock to keep the clock time. In satellite mode, this RTC could be set during configuration with a reader during entry.

  • Page 13: Handling Recommendations

    Warning: For the DMC 3000 vibrator alarm to be effective, the unit must be in contact with the body for the user to feel it. As the energy range of the DMC 3000 starts at 15 keV, the detection area of the dosimeter should not be covered with any heavy material, like metal, in order to ensure the most accurate dose measurement.

  • Page 14: 3- Operation

    - In fast entry, as soon as the dosimeter switches back to Pause mode, the fast entry mode is disabled. To return to fast entry mode set parameters again. - If the permanent fast entry mode is set, the DMC 3000 will revert to fast entry mode when back in Pause.

  • Page 15: 4- States Modes

    DMC 3000 User's Guide The sleep mode state is a low-power consumption state where the functional indicator ":" does not blink. When either button is pressed, or during communi- cation with a reader, the DMC automatically goes into Pause with a backlit display and all display segments activate for 2 seconds.
