Abstract: In association with a method and a device for sensory measurement of a material sample, a measurement curve is used to detect deviations from the regular measuring characteristics of the device. A corresponding file can be made available to a service technician for evaluation.

Abstract: A method, as applied to a program-controlled measuring instrument, determines an observable property of an object. The program-controlled measuring instrument has a diagnostic measurement program that is executed by a user. The diagnostic measurement program stores data related to the execution of the diagnostic measurement program and maintains the data for remote transmission to a remote service entity.

Abstract: A method for controlling electronic records produced by an application software program for an analytical laboratory apparatus includes (a) restricting access to the application software program to designated users performing assigned user roles; (b) assigning a set of user rights to each user role; (c) storing the records in a protected data file format; (d) maintaining an audit trail of log-on's and activities performed in the application software program; and (e) authenticating the electronic records by means of at least one electronic signature. The designated users are divided into a first group who are given a right to sign the electronic records and a second group who are not given the right to sign electronic records, and access to step (e) is denied to users of the second group.

Abstract: A method and apparatus for thermally investigating a material by driving the material through a temperature profile composed of isothermal and non-isothermal segments is disclosed, which enable determination of a kinetic component in a measured heat flow signal caused by the exposure of the material to the temperature profile.

Abstract: A method and apparatus for thermally analyzing a sample of a material by detecting a heat flow between the sample (7) and a heat source (1) and evaluating a functional relation between the measured heat flow (HF) and an associated temperature is based on controlling the heating power of the heat source (1) so as to cause the heat source to follow a temperature program (17) as a function of time superposed with a modulation (23) of the heating power.

Abstract: A heat flow calorimeter comprises a single sample holder (5) in thermal contact with a heat source (1). A temperature difference over mutually spaced locations (11, 12) along a heat flow path between sample (23) and heat source (1) is measured. The measured signal (24, 25) is combined with a compensation signal from a signal source (34) to derive a compensated temperature difference signal representative of the net heat flow to sample (23), (FIG. 1).
