ii). NiMH: Panasonic Rechargeable BK200AAB,
iii). See also Table 4:5 – Battery Specification.
c) The typical capacity for battery types operating FlowTracker2 are the following.
This is dependent on the brand of battery used and the environmental conditions
that it is exposed to. Battery capacity estimates are based on voltage and are
only approximate, particularly for rechargeable batteries where voltage
characteristics can change significantly over the life of the batteries.
i). 8 x size AA: ≈ 15 hours continuous use with typical settings.
The typical settings used for determining the battery capacity indicated above are
based on the following,
• Operating screen at 100% brightness,
• ADV sensor pinging at 50% of the measurement time,
• No sleep periods,
• GPS off.
Cold weather can greatly affect battery voltage and capacity; always check battery
voltage after the system has acclimated to outside temperatures.
Battery manufacturer guidelines must be followed during normal use, long term storage
and charging requirements. The disposal of batteries must be done with care and it is
recommended that local authority guidelines be used.
Battery Voltage 4.3.2
The Battery Voltage displayed is the current battery voltage level available from the
batteries installed in the FlowTracker2 handheld.
Percentage Full 4.3.3
The Percentage Full is an estimate of the remaining capacity of the battery as a
percentage of the full capacity.
When the remaining capacity of the battery reaches 0%, the FlowTracker2 handheld
will supply the following message, “Battery level critically low – shutting down”. The
user will be required to replace the batteries before continuing with operations.
4.4. Raw Data Display
Raw Data function allows the graphical display of raw time series data measured by the
FlowTracker2. The raw time series data are displayed with the units as shown below.
