Slope (relative)
Designation used by WTW in the D. O. measuring technique. It ex-
presses the relationship of the slope value to the value of a theoretical
reference probe of the same type of construction.
Standard solution
The standard solution is a solution where the measured value is
known by definition. It is used to calibrate a measuring system.
Temperature
coefficient
Value of the slope of a linear temperature function.
Temperature function
Name of a mathematical function expressing the temperature behav-
ior of a test sample, a probe or part of a probe.
Test sample
Designation of the sample ready to be measured. Normally, a test
sample is made by processing the original sample. The test sample
and original sample are identical if the test sample was not processed.
