3.2 CHARGING
If the TL-3.0 is being powered by a battery pack then a suitable 5VDC power source
can be connected to the charging connection described in section 2.6. The power
source can be supplied from any PC/laptop or any mains to USB charger plug of
suitable quality that provides a 5VDC output and 500mA current.
WARNING! DO NOT CHARGE BELOW 0°C
It is the responsibility of the OEM to ensure the battery being used is suitable for the
application and to determine if it can be charged. DO NOT CHARGE ALKALINE
BATTERIES.
WARNING: Cheap charging devices often fail to meet the requirements of the
Electrical Equipment Regulations Act 1994, as a minimum any charger plug
must have a CE mark (shown right) and it is the responsibility of the operator
to ensure any charger plug is safe to use.
The time taken to fully charge the TL-3.0 will depend on the type of charger, a simple
calculation is:
Charge Time (hours) = Battery capacity (mAh) ÷ charging current (mA)
For example:
2000mAh battery capacity charging from a laptop at 500mA:
2000 ÷ 500 = 4 hours
The battery life of the TL-3.0 depends on the how it is being used, the lower the
sample rate the longer the battery life will be. One example is:
