Baud Rate
Baud rate is the speed at which digital devices transfer information. The flow meter has
a default baud rate of 19200 baud (bits per second). If your computer or software uses a
different baud rate, you must change the flow meter’s baud rate in the
BAUD
menu
to ensure
they match. Alternatively, you can change your computer’s baud rate in Windows® Device
Manager. Baud rate changes take effect once you press
SET
