Number Technical Information The Hp(0,07) Beta Module is mounted on a DMC 3000 to expand the DMC 3000’s measurement capabilities to beta radiation, and turn on the Hp(0,07) Gamma + Beta measurement. This user’s guide is to be used along with the DMC 3000 user guide (n°151153EN). -
Page 4: 2- General
Hp(0,07) Beta Module. For the Hp(0,07) Beta Module to work correctly, it must be paired with a DMC 3000 using firmware V07.1.0 or greater. If the dosimeter displays a star at the bottom of its screen, firmware version is earlier than V07.1.0 and is not suitable. -

2.2 Settings The Hp(0,07) Beta Module itself contains all the proper functional settings and calibration parameters. These parameters are saved in the module on non-volatile memory. 2.3 Hp(0,07) Measurement Display In the standard configuration for the DMC 3000, display of the Hp(0,07) Gamma + Beta measurements are automatic after connection of the module. -
Page 6: Hp(0,07) Chirp Doses Increment
The belt clip is strongly discouraged when a module is attached on the dosimeter because the opening gap of the clip is significantly reduced. The use of the front facing clip and dosimeter inside the pocket is forbidden with an Hp(0,07) Beta Module, because no material must be in front of the Beta detector. -

Page 13: 5- Manual Calibration & Maintenance
5.1 Principle The Hp(0,07) dose are linked to the number of counts detected by the following formula: Hp(0,07) dose = f (counts) K x KMul K is the factory efficiency coefficient and cannot be changed by the user. KMul is the efficiency coefficient multiplier that can be changed by the user. The Hp(0,07) manual calibration need to be performed in two steps, first step with a Gamma source and the second with a beta source. -
