Data Byte #6-#9
Transmitter Variable Lower Range Value, IEEE 754, in the RangeUnits. For flowrate
variables is assumed to be zero; hence this variable is ignored by transmitter and sent back as
м0о.
NOTE: For the ReverseFlow the Upper Range Value is stored in EEPROM (if accepted) but will be actually used by the
instrument only when the ReverseScaleControl (refer to Command #156) is set to zero (ìDifferentî) and the function of
any output is set to either ìForward/reverse flowî or to ì2 Dirî (refer to Command #138).
Refer also to comments for Command #35, Write Primary Variable Range Values.
