C-2

Density, Air

Density of the air used to computer the buoyant effect of air on the masses. May be

entered directly or computed from ambient temperature, humidity and pressure.
Density, Gas

Density of the gas medium used to compute head corrections. Gas density may be entered

directly or may be computed from the gas used and the current pressure.
Density, Oil

Density of the oil medium used to compute head corrections. Oil density may be entered

directly or may be selected from the list of available mediums.

Density, True

The actual density (mass per unit volume) of the mass or piston. See also Reference

Density; Density of Air; and Mass Apparent.

DUT

Device under test, the device being calibrated.

Elevation

Elevation above sea level for computing approximate Gravity.
Float Position

Distance of the piston from mid-float. Positive values are higher, negative values are

lower than mid-float.
Formula

Calculates the variable using other variables. See Gravity; Air Density.
Gauge

Pressure measurement referenced to current atmospheric pressure.
Gravity

Force of gravity on the masses. May be entered directly or computed from Latitude and

Elevation.
Gravity Factor

Mass correction factor for local gravity.
