Glossary
Smallest difference between two measured values that can be dis-
played by a meter.
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.
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
Vessel that takes a liquid sample for measurement.
LED
Light Emitting Diode
LEDs are used as the light source in the Turb 430 IR/T.
The measuring system comprises all the devices used for measuring,
e. g. measuring instrument and probe. In addition, there is the cable
and possibly an amplifier, terminal box and armature.
The measured parameter is the physical dimension determined by
measuring, e. g. pH, conductivity or DO concentration.
Designation of the test 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.
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 is the quantity (in Mol) of a dissolved substance in 1000 g sol-
vent.
Restoring the original condition of all settings of a measuring system.
The standard solution is a solution where the measured value is
known by definition. It is used to calibrate a measuring system.
