Terms for subject Metrology (318 entries)

characteristic	A line which shows the values, in steady state, of an output variable of a system or device as a function of the input variable, the other input variables being maintained at specific constant values. When the other input variables are treated as parameters, a set of characteristic curves is obtained
characteristic curve	A line which shows the values, in steady state, of an output variable of a system or device as a function of the input variable, the other input variables being maintained at specific constant values. When the other input variables are treated as parameters, a set of characteristic curves is obtained
C-A thermocouple	chromel-alumel thermocouple
Class I, II or III equipment	Classification of protective measures for current carrying components
climate class	The climatic conditions, i.e. ambient temperature, pressure and humidity, to which the measuring equipment can be subjected during operation (including shutdown) transport and storage
closed-control loop	A combination of control units in which the process variable is measured and compared with the desired value (set point) If the measured value differs fom the desired value, a corrective signal is sent to the final control element to bring the controlled variable to the proper value
CMC	Calibration and Measurement Capabilities	carp
Commutec transmitter	Intelligent E+H transmitters
conformity	The closeness with which a calibration curve approximates to a specified characteristic curve (which can be linear, logarithmic, parabolic, etc.) It is usually measured in terms of nonconformity and expressed as conformity
conformity error	The absolute value of maximum deviation between the calibration curve and the specified characteristic curve
connection compartment	A separate compartment or part of a main enclosure, communicating or not with the main enclosure, and containing connection facilities
CVGT scale	constant-volume gas thermometry scale
CW laser	continuous wave laser
CRASTIN®	Tradename for PBTP and PETP
custody transfer	The term which describes this whole business
custody transfer measurement	The mode in which the instrument must operate to make such measurements
custody transfer mode	The mode in which the instrument must operate to make such measurements
CVGT scale	constant-volume gas thermometry scale
CW laser	continuous wave laser
D-action	derivation action
