* The Total and Grand Total values are available in 3 formats:
64-bit in a single register, 64-bit in four consecutive 16-bit
registers and 32-bit in two consecutive 16-bit registers. The
64-bit format is recommended for greater precision, especially
with values greater than 7-digits.
Temperature, Pressure, Density and Viscosity are available in
†
16-bit registers in firmware versions 1.020821 and later.
