2.7 Module Management The Module Management Mode is configurable using DMCUser software. None: any physical connection of module is ignored by the dosimeter. „ All: DMC 3000 accepts all type of module. When a module is connected the dosimeter changes automatically „... -
Page 9: 3- Alarms
3.1 Alarm Display and Configuration The Hp(10) neutron dose and dose rate warnings and alarms are configurable for the entire measurement range from 1 µSv to 10Sv (0.1 mrem to 1000 rem) and from 100 µSv/h to 10 Sv/h (10 mrem/h to 1000 rem/h). The Hp(10) neutron multiplier efficiency coefficient can alter the precision performance at low dose rates and modify the neutron dose increments size. -

5.1 Principles The neutron dose is linked to the number of counts by the following formula: f (counts) N dose = Kn x KnMul x KnTask Kn is the factory efficiency coefficient and can not be changed by the user. „... -
Page 15: Manual Hp(10) Neutron Calibration
The Neutron Module is calibrated at the factory using established procedures and international standards (ISO/CEI 17025). Mirion Technologies recommends an annual verification of the dosimeter’s calibration. However, the frequency of this verification may be defined by the client according to the conditions and frequency in which the dosimeter is used, and according to local regulation. -
Page 16: Maintenance
5.3 Maintenance Mirion Technologies recommends full inspections of dosimeters at a minimum of once a year. Calibrations (Gamma and Neutron): see §5.2 „ Functions: check that the DMC 3000 displays and Neutron dose by pressing the "-" key. „ Check the auto-test when the DMC 3000 exits standby mode: the speaker will chirp once, ‰... -
