Power Supply
Battery Operation
Introduction
The SMART THUMP can be equipped with an internal battery. In this case
there is no requirement for an AC line supply to operate the unit in the field. For
a good trade-off between weight and operation time, the battery is sized for up
to more than 400 capacitor discharges at 90% of full voltage which equals
approximately 1 hour of thumping (pinpointing).
Battery Status and Automatic Shutoff
As long as more than 50% of the battery capacity is available, no battery icon is
shown on the screen. As soon as the battery is discharged by more than 50%, the
battery icon
in the upper right corner of the screen starts flashing (
not
an active
bar graph).
Battery capacity >50% Battery capacity <50%
To protect the battery from a deep discharge, the unit turns automatically off, if
the battery is discharged too low for safe operation.
Note: To find out whether the battery charge is sufficient for further use of the
unit in the field, just turn the unit on and check if the battery symbol is
visible on the main screen. If the symbol is visible you should strongly
consider recharging the battery before using the unit or plan to operate off
AC line power.
