Glossary
Adjusting To manipulate a measuring system so that the relevant value (e.g. the
displayed value) differs as little as possible from the correct value or
a value that is regarded as correct, or that the difference remains
within the tolerance.
AutoRange Name of the automatic selection of the measuring range.
Calibration Comparing the value from a measuring system (e.g. the displayed
value) to the correct value or a value that is regarded as correct.
Often, this expression is also used when the measuring system is
adjusted at the same time (see adjusting).
Cell constant, k Characteristic quantity of a conductivity measuring cell, depending on
the geometry.
Conductivity Short form of the expression, specific electrical conductivity.
It corresponds to the reciprocal value of the resistivity.
It is a measured value of the ability of a substance to conduct an
electric current. In water analysis, the electrical conductivity is a
dimension for the ionized substances in a solution.
Measured parameter The measured parameter is the physical dimension determined by
measuring, e.g. pH, conductivity or D.O. concentration.
Measured value The measured value is the special value of a measured parameter to
be determined. It is given as a combination of the numerical value and
unit (e. g. 3 m; 0.5 s; 5.2 A; 373.15 K).
Molality Molality is the quantity (in Mol) of a dissolved substance in 1000 g
solvent.
