Yokogawa 415 Steam and Gas - Manual (Page 63)

Flowrate Decimal The number of decimal points with which the
flowrate is displayed.
Total Decimal The number of decimal points with which the
total is displayed.
Temperature Offset This allows a small offset to be programmed to
correct for any offset error in the RTD. For
example, if during "TEST" the temperature was
read at 125.3°C when it was known that the
actual temperature was really 124.8°C, then an
offset of -0.7°C could be programmed to correct
for the error in the RTD.
Pressure Input Both absolute and gauge pressure systems can
be used with the Model 415.
Atmospheric Pressure If a gauge pressure sensor is used, the
atmospheric pressure must be programmed
since this will vary with the altitude of the
installation.
Note that the Absolute Pressure = Atmospheric
Pressure + Gauge Pressure. The atmospheric
pressure will default to 101.325 kPa (14.696
psia) which is the standard value at sea level.
