3.9.1 Battery Status
Introduction to the TSC1 Datalogger 3
The status line displays the status of the TSC1 battery and of any
external power source (usually a receiver), depending on the source
currently being used. For a list of items that appear in the status line,
refer to the TSC1 Asset Surveyor Software User Guide.
You can also view the power status by selecting Configuration /
Hardware (TSC1). TheInternal battery and External battery fields
show how much power remains, and indicate whether the source being
used by the TSC1 datalogger is internal or external.
The values for the Internal battery and External battery fields are
expressed as percentages, and are calculated by comparing the
reported voltage against the possible range for the power source in
question.
For example, the percentage displayed for the External battery field is
computed by comparing the reported voltage against the possible
voltage range (vmin to vmax ) for camcorder batteries, as follows:
External battery % = (voltage – vmin )/(vmax –vmin ) × 100
The percentage displayed for the Internal battery field is computed by
comparing the reported voltage against the possible range for the
lithium-ion battery, as follows:
Internal battery % = (voltage – vmin )/(vmax –vmin ) × 100
Note – The percentage reported for new batteries may be less than
100%. The calculation of the battery percentage assumes a range
typical of a new battery, so used batteries may report percentages well
under 100%. This is because repeated recharging of batteries
normally results in a reduced potential maximum voltage.
