Abstract: A method for remote control of an app for measuring, calibrating, and/or adjusting a sensor in process automation technology includes connecting the sensor to a handheld measuring device having at least one operating button; establishing a data connection from the handheld measuring device to a mobile device, wherein an app is executed on the mobile device; actuating the operating button and transmitting the function or data stored in the operating button to the app of the mobile device via the data connection; and processing the function or data in the app.

Abstract: A device is described for gravimetric testing of multi-channel pipettes having two or more pipette channels. The device has one receptacle (9) per pipette for a test volume or for a container (2, 20) containing the test volume, and in addition, one weighing cell (1) per receptacle (9) for weighing of the container (2, 20) and/or of the test volume.

Abstract: A drive system includes an electric machine with a rotor arrangement which is connectable to a drive shaft for joint rotation therewith and a stator arrangement. The drive system further includes a coupling device such as a hydrodynamic coupling device with an inlet region that is connectable to the drive shaft for joint rotation therewith. A coupling element that is connectable to the drive shaft supports a rotor interaction region of the rotor arrangement is connectable to the inlet region of the coupling device for joint rotation.
