Overview ProLab 2000 ID sensors SI Analytics ID sensors support the automatic sensor recognition function. Their sensor designation has the addition "ID", e.g. A 161 1M DIN-ID electrode. Note Information on available ID sensors is given on the Internet or directly by SI Analytics. ID sensors connected to the ProLab 2000 meter can be recognized by the ID sensor symbol on the display of the meter. pH 7.000 ID sensor symbol 25.0 °C 26.04.
ProLab 2000 Overview 1.6 Electronic access control The ProLab 2000 always documents measurement data and calibration data with an ID number (USER ID). If the USER ID is assigned to a certain user, all measurement data is also assigned to the user in compliance with GLP. The USER ID is easily and safely transmitted to the ProLab 2000 via an electronic key. Each electronic key in the form of a keyring pendant contains a key number.

ProLab 2000 Lists 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.
Lists ProLab 2000 Molality Offset potential The measurable potential of a symmetrical electrode, the membrane of which is immersed in a solution with the pH of the nominal electrode zero point. The asymmetry is part of the offset potential. ORP voltage The ORP is caused by oxidizing or reducing substances dissolved in water if these substances become effective on an electrode surface (e. g. a gold or platinum surface). pH value The pH is a measure of the acidic or basic effect of an aqueous solution.
ProLab 2000 Lists Temperature coefficient Temperature compensation Temperature function Test sample Zero point ba75577e05 11/2013 Value of the slope of a linear temperature function. Name of a function that considers the temperature influence on the measurement and converts it accordingly. Depending on the measured parameter to be determined, the temperature compensation functions in different ways. For conductimetric measurements, the measured value is converted to a defined reference temperature.
