Glossary

 

A set of operations, under specified environmental conditions, that establish the relationship between measured values of the equipment under test and the corresponding values of the reference standards or materials.

Calibration and Measurement Capability
The highest level of calibration or measurement accuracy available to a customer, provided by the calibration laboratory. Also known as Best Measurement Capabilities (BMC). Click here to view more about our CMC's.

 

The measure of the ability of a material or solution to carry an electrical current. Unit of measure is the Siemens (S).

 

The range of values that encompases the standard uncertainty multiplied by the coverage factor. In the formula below, ± ks represents the confidence interval.

value = m ± ks

value = value of the measurement
m = measurement (or mean of measurements)
k = coverage factor
s = standard uncertainty

 

A numerical factor k is used as a multiplier of the combined standard uncertainty in order to obtain an expanded uncertainty. In general, the value of the coverage factor k is chosen on the basis of the desired level of confidence to be associated with a measurement. With a normal distribution, k=2 giving a level of confidence of approximately 95 % that the measured value m is within ± ks of the value.

value = m ± ks

value = value of the measurement
m = measurement (or mean of measurements)
k = coverage factor
s = standard uncertainty

 

The rate of flow of electricity. The unit of measure is the ampere (A).
