What happens if the battery becomes fully discharged while sampling?
When the voltage of the external battery pack reaches 5.1 volts or less, the battery pack will automatically shut off. If the DUSTTRAK does not have an auxiliary power source (internal C-cell size batteries), it will turn off and the sample will be terminated. All data stored in the internal memory will be left intact due to the DUSTTRAK’s internal lithium battery back-up feature.
