  • Page 12: Power Consumption

    POWER CONSUMPTION The batteries consumption depends from the setting of the followings elements: main board, sampling interval (measure profile), sensor diameter, frequency of data delivery, amount of data collected, interface activities (display). Special software to calculate the consumption is available; here below a simple scheme to evaluate the different “consumption’s rate”...
  • Page 13 POWER TOOL SOFTWARE Power tool is a software which allows to evaluate the converter battery life. The estimation is done with easy guided procedure Low power consumption: a number of design strategies have been employed to achieve exceptionally low power consumption. However, the length of time between battery changes depends on a quality/status of batteries, the frequency of sampling and logging.
