ACCURACY
A number or quantity which defines the limit of error under reference conditions.
ATTENUATION
A decrease in signal magnitude between two points, or between two frequencies.
DEAD TIME
The interval of time between the initiation of an impact change or stimulus and the start of the resulting response.
DRIFT
As an undesired change in output over a period of time, which change is unrelated to input, operating conditions, or load.
ERROR
The difference between the indication and the true value of the measured signal.
SPAN ERROR
It is the difference between the actual span and the specified span and is expressed as the percent of the specified span.
ZERO ERROR
It is the error of device operating under the specified conditions of use when the input is at the lower range value.
STATIC GAIN
It is the ratio of the output change to an input been change after the steady state has been reached.
HYSTERESIS
The maximum difference between the upscale and downscale indications of the measured signal during a full range traverse for the same input.
INTERFERENCE
Interference is any spurious voltage or current arising from external sources and appearing in the circuits of a device.
COMMON MODE INTERFERENCE
It is the form of interference which appears between the measuring circuit terminals and ground.
NORMAL MODE INTERFERENCE
It is the form of interference which appears between measuring circuit terminals.
LINEARITY
The closeness to which a curve approximates a straight line.
RANGE
The region between the limits within which a quantity is measured received or transmitted, expressed by stating the lower and upper range values.
REPEATABILITY
The closeness of agreement among a number of consecutive measurements of the output for the same value of the measured signal under the same operating conditions.
REPRODUCIBILITY
The closeness of agreement among repeated measurements of the output for the same value of the input made under the same operating conditions.
RESPONSE
It is the general behavior of the output of a device as a function of input both with respect to time.
SIGNAL TO NOISE RATIO
A ratio of signal amplitude to noise.
TIME CONSTANT
The time required for the output to complete 63.2 % of the total rise or decay.
SPAN:
The algebraic difference between the upper and lower range values.
ZERO SHIFT
Any parallel shift of the input-output curve.
