Cond 315i Lists Lists This chapter provides additional information and orientation aids. Abbreviations The list of abbreviations explains the indicators and the abbreviations that appear on the display and in the manual. Specialist terms The glossary briefly explains the meaning of the specialist terms. How- ever, terms that should already be familiar to the target group are not described here. - Page 34 Lists Cond 315i Abbreviations Conductivity value (international γ ) AutoRead (drift control) ARng Automatic range switching Measuring instrument measures with highest reso- lution Cell constant [cm ] (internat. k) °C Temperature unit, degrees Celsius Calibration LoBat Batteries almost empty (Low Battery)
- Page 35 AutoRange Name of the automatic selection of the measuring range. AutoRead WTW name for a function to check the stability of the measured value. 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. Of- ten, this expression is also used when the measuring system is adjust- ed at the same time (see adjusting).
- Page 36 Lists Cond 315i Salt content General designation for the quantity of salt dissolved in water. 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.
