Abstract: The invention relates to a method 100 for determining a pressure in a vacuum system, wherein the method comprises the steps of: a) generating 101 a plasma in a sample chamber which is fluid-dynamically connected to the vacuum system and which is in electrical contact with a first electrode and a second electrode; b) measuring 102 a current intensity of an electrical current flowing through the plasma between the first electrode and the second electrode; c) measuring 103 a first radiation intensity of electromagnetic radiation of a first wavelength range which is emitted from the plasma, wherein the first wavelength range contains at least a first emission line of a first plasma species of a first chemical element; d) measuring 104 a second radiation intensity of electromagnetic radiation of a second wavelength range which is emitted from the plasma, wherein the second wavelength range contains a second emission line of the first plasma species of the first chemical element or of a second plasma species of th

Abstract: The invention relates to a capacitive vacuum measuring cell having a first housing body (1) with a membrane (2) which is arranged at a distance therefrom so as to form a seal in the edge region (3) in such a way that a reference vacuum space (9) is formed therebetween, wherein opposite surfaces (7, 8) of the first housing body and of the membrane (2) comprise at least one electrode (G, G1, G2, . . . Gn, M1, M2, . . . Mn). A second housing body (4) is provided so as to form a seal with respect to the membrane (2) in the edge region and forms, with said membrane, a measuring vacuum space (10) in which connection means (5) are provided for connection to a process space.

Abstract: Calibrating a measuring cell arrangement having a diaphragm vacuum measuring cell having a programmable heater for heating the diaphragm vacuum measuring cell to a constant presettable temperature. The heater encompasses the measuring cells and is encompassed by an insulation jacket. The method includes setting a first heating temperature on the measuring cell to a constant preset value, performing a first calibration step by generating at least one preset pressure in a vacuum volume and obtaining vacuum measuring signals of the measuring cell and at least one reference measuring cell, storing pressure values in the memory, determining compensation values from the difference values of the measuring cell and the reference measuring cell, intermediately storing these difference values in a calibration data memory and gauging the measuring cell by transmitting the determined compensation values to the measuring cell data memory.

Abstract: The invention relates to a method for programming an operating device for lighting, wherein the operating device comprises firmware and an interface for receiving external control commands for operating the lighting. This method includes at least partially programming the firmware of the operating device or the interface by transmitting additional information to the interface. This can conveniently be accomplished while the operating device is in operation. Typical lighting of the invention is the type that includes an electronic ballast for gas discharge lamps.
