Conductive ink compositions which can be cured to highly conductive metal traces by means of \u201cchemical welding\u201d include additives which reduce the curing temperatures for use with low-temperature substrates. The switching means includes switches that switch between a first wiring configuration for electrically connecting the first measuring means to the device under test and a second wiring configuration for electrically connecting the second measuring means to the device under test. The image data attached to the e-mail as an openable document. The stationary unit includes a first and a second partial ring stator segment that are at least partially retained in the housing unit, leaving a stator distancing gap in which at least one Hall-effect IC switch is positioned.
