2.13. USB interface
The unit has an female USB micro-B connection (DIN 62684) that can be used as an external
power supply and to upgrade the firmware (USB micro-B is the same connector you find on most
Android and Windows portable phones, you can use the charger of your telephone to power the
DB04A
). It is not possible to read data from the flow meter through the USB connection.
2.14. Battery
The battery operated DB04A can operate on any common AA battery. The lifetime is strongly
dependent on the usage and the quality of the battery. In general we can state that the battery
lasts for about 3-6 months under non-continuous use.
We recommend to use external power (USB micro-B or 24 Vdc) if you application needs
continuous measurement like measuring totalized flow. To extend the lifetime of the battery, the
back-light is disabled during battery operation, you cannot activate it. We strongly recommend to
use the “
auto power off”
in the menu for battery driven devices.
