RUNNING AND OPERATING BASIC PROCEDURES
4.1
CHARGING
The battery inside
SV 104IS
uses lithium-ion technology which requires special consideration and
handling techniques due to the extremely high energy density
(see “SPECIAL PRECAUTIONS WHEN
USING AND CHARGING LITHIUM BATTERIES
Ensure the
SV 104IS
is fully charged prior to use by placing it onto the docking station charger.
Ensure the power supply is connected and the supply is switched on. In charged enough state (internal
battery voltage above 2.9V) the
SV 104IS
will automatically turn on the display during charging and present
how much charge is within the instrument. The
SV 104IS
will display ‘Fully charged’ once charging is
complete. This should take approximately 4 hours from a fully discharged state. A charging time of about
1 hour will be sufficient to perform greater than 10 hours of measurement. A fully charged instrument holds
enough charge to run for more than 50 hours (typically 60 hours).
Note that once disconnected from docking station, the dosimeter will automatically switch off. If put
again onto the docking station the internal battery is float charged. This keeps the battery performance
in steady condition. If the battery is fully discharged prior to being placed on a charger, it trickle charges for
a maximum 1h time prior to the fast charge cycle, this prevents damage to the batteries.
The number of hours you have used your dosimeter from your last charge will impact your total charge
time. For example, if the battery clock indicator displays 10 hours remaining on the battery and you wish to
charge the battery, the approximate charging time is 3 hours.
