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.
