Reference Density
Assumed density of the mass standard used to calibrate the mass. For mass values
reported under the designation Apparent Mass versus Brass Standards, the Reference
Density is typically 8.4 g/cm
3
. For the designation Apparent Mass versus Stainless Steel
Standards, the Reference Density is typically 8.0 g/cm
3
. The appropriate value must be
used for the Reference Density to achieve proper buoyancy corrections for gauge mode
operation. For more information see Mass True; Mass Apparent.
Reference Pressure
The pressure all other pressures are measured against. See Absolute; Gauge.
Requires
Indicates what other mass (e.g. hanger mass) is required before the selected mass can be
loaded onto the piston.
Rotation
Direction the masses are rotating when measurement is taken.
