Voltage to Frequency Board
The Voltage to Frequency board (ADS p/n 5000-0661) allows the
FlowShark IS monitor to safely read the internal battery voltage.
The user can access the internal monitor voltage during data collects
to determine whether sufficient voltage is available to power the
FlowShark IS monitor. If the voltage drops below a threshold of 6.5
volts, the user will receive a warning that the battery pack requires
replacement.
