摘要： Measurement amplification methods and devices for detecting the detuning of a measurement bridge (10) to which a bipolar, rectangular supply voltage (Us) is supplied. The methods and devices use integrating A/D conversion and are characterized in that a reference voltage (Uref) used for the A/D conversion undergoes polarity changes synchronized with the polarity changes of the supply voltage (Us). Offset and drift are eliminated by totaling an even number of individual measurements.

摘要： Measurement amplification methods and devices for detecting a monopolar input signal (UE) by integrating A/D conversion. Before being digitized, the input signal (UE) is inverted according to the so-called Chopper principle and converted into a bipolar intermediate signal (UZ). A reference voltage (Uref) used in A/D conversion undergoes polarity changes synchronized with the polarity changes of the intermediate signal (UZ). Offset and drift are eliminated by totaling an even number of individual measurements.

摘要： An analytical balance that includes a balance scale, a wind guard encircling the balance scale, and an apparatus for generating an ionized stream of air for dissipating electrostatic charges of goods to be weighed. The apparatus for generating an ionized stream of air includes a blower that draws in air from the weighing space into at least one boundary surface of the weighing space. The blower also recycles the air back into the weighing space via at least one exhaust opening at another point. In this manner, highly effective dissipation of electrostatic charges is possible, and the stream of air can be conducted so that it exerts scarcely any vertical forces on the goods to be weighed. The analytical balance is very user-friendly in operation. Additionally, the apparatus for generating an ionized stream of air is preferably structured to be an easily installed optional component of the analytical balance.
