6.1 Factory settings
The current loop is set in such a manner that 4 mA corresponds to zero flow and
20 mA corresponds to its maximum value.
The address of the meter is set to 1 by default and communication parameters to
2400Bd, 8db, 1sb, parity EVEN (Mbus) or 9600Bd, 8db, 1sb, no parity (Modbus).
Access password (PIN) for parameter changing is always set to 0000 and this
value will be reset in case of restoring to factory default settings.
