The invention relates to a methodfor determining a pressure in a vacuum system, wherein the method comprises the steps of:

Method for detecting pressure, and pressure sensor

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.

Method for calibrating and operating a measuring cell arrangement

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.

Method for programming an operating device for lighting means

A method for the monitoring of transmissions in a transmission branch of a bidirectional interface, which besides the transmission branch has a reception branch standing in connection with the transmission branch, has the steps a) sending out of information by means of the transmission branch, and b) evaluation of defined characteristics of the sent information via the reception branch of the same interface, whereby preferably depending on the evaluation of the sent information a setting of parameters of the transmission branch is effected, so that future information is sent out with use of these parameters.

Method for the monitoring of transmissions of a bidirectional interface

Introduced is a method for the production of a diaphragm vacuum measuring cell, wherein on the one side of the diaphragm () at a spacing a first housing plate () is disposed sealing in the margin region with a joining means (), and that on the other side of the diaphragm () at a spacing a second housing plate () is disposed sealing in the margin region with a joining means (), and that the second housing plate () has an opening at which a connection means () is disposed sealing with joining means () for the connection of the measuring cell () with the medium to be measured, wherein the diaphragm () and the two housing plates () are comprised of a metal oxide. Using an ALD method, the measuring cell is coated in a vacuum chamber (), in particular through the opening of the measuring cell, such that the inner wall of the measuring vacuum chamber () and the opening with the connection means () is covered with a protective layer () such that at least the joining means () for the diaphragm () is protectively covered against corrosion.
