Overview of running a study

Checking battery power

Typically, the life of the battery is approximately 60+ hours (see Appendix A for specific specifications). The dosimeter can be charged at any time by using your EdgeDock.

There are two battery identifiers on the dosimeter which are the battery indicator icon and the battery power clock (see Figure 4-3).

Checking battery power

1.The battery indicator icon (located at the top right of your screen) gives an approximation of battery life and is always present.

∙If the battery indicator is half shaded, this illustrates you have approximately 30 hours of battery life remaining.

∙If lobat appears, less than 8 hours of run time is available.

2.Additionally, there is a battery time remaining measurement which identifies the number of hours and minutes remaining on the dosimeter.

3.To view, press the up/down arrows . This will navigate your through the views of the dosimeter.

NOTE: The battery time remaining measurement can be disabled from the view of the meter. See Chapter 3 for explanation on changing the display.

Battery indicator icon When fully shaded, this indicates full battery life.
