Page 7: Historical Data Function
2.3 Historical Data Function DMC 3000 series dosimeters have a historical data function which allows the following features: Recording and storage of changes greater than 1 µSv (0.1 mrem) in the cumulative Hp(10) dose by „ intervals of 10 seconds, 1 minute, 10 minutes, 1 hour or 24 hours depending on the dosimeter’s configuration. Recording and dating of significant events such as: „... -
Page 8: Handling Recommendations
2.4 Handling Recommendations As the DMC 3000 offers the ability to clip it either outside the pocket, (standard or belt clip) or inside (front side clip), users should remember to wear the dosimeter with its back side facing the body. (See label on the battery cover.) 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. -
Page 9: 3- Operation
3.1 Fast Entry Mode The DMC 3000 can be started up using a simplified and quick procedure. Fast entry must be enabled using User software. When fast entry is enabled, the message "ENtER" (1) is „ displayed. Simply pressing one of the 2 control buttons immediately switches the DMC 3000 dosimeter into Run mode. -
Page 10: 4- States Modes
The sleep mode state is a low-power consumption state where the functional indicator ":" does not blink. It is an optional factory configuration. 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. -
