Operators Manual
transfer error
The sum of all new errors induced during the process of comparing one quantity against
another.
transfer standard
Any working standard used to compare a measurement process, system or device at one
location or level with another measurement process, system, or device at another location
or level.
transport standard
A transfer standard that is rugged enough to allow shipment by common carrier to
another location.
true value
Also called legal value, the accepted, consensus, (i.e., the correct value of the quantity
being measured).
uncertainty
The maximum difference between the accepted, consensus, or true value and the
measured value of a quantity. Uncertainty is normally expressed in units of ppm (parts
per million) or as a percentage. (Accuracy is the same as 1 - % uncertainty.)
units
Symbols or names that define the measured quantities. Examples of units are: V, mV, A,
kW, and dBm. See also "SI System of Units."
UUT (Unit Under Test)
An abbreviated name for an instrument that is being tested or calibrated.
volt
The unit of emf (electromotive force) or electrical potential in the SI system of units. One
volt is the difference of electrical potential between two points on a conductor carrying
one ampere of current, when the power being dissipated between these two points is
equal to one watt.
watt
The unit of power in the SI system of units. One watt is the power required to do work at
the rate of one joule/second. In terms of volts and ohms, one watt is the power dissipated
by one ampere flowing through a 1Ω load.
wideband
AC voltage at frequencies up to and including the radio frequency spectrum.
