    摘要： The invention relates to weighing equipment having a load receptacle (12) and a control circuit (30) comprising a controller (34), by means of which a load-dependent deflection, which can be detected by means of a position sensor (32), of a transmission lever (22) coupled to the load receptacle (12) can be compensated by a counter-force of a controlled, powered electromagnet (26, 28), wherein the electromagnet (26, 28) can be excited to oscillations of the magnetic force thereof so that resulting deflection changes to the transmission lever (22) have the effect of a redistribution of a free-flowing sample positioned on the load receptacle (12). The invention is characterized in that the controller (34) has at least one active controlling element (46) which is connected to at last one passive tuning element (48) for tuning at least one control parameter, wherein the controller (34) has at least one passive tuning element (40), which can be connected as an additional or alternative tuning element, wherein the connecting thereof can destabilize the control circuit (30).

    摘要： The invention relates to a measuring device for the thermogravimetric determination of material moisture, comprising a base (12), which is designed as a scale and which has a base surface (22), which forms at least one scale-space bottom and through which a scale-plate support passes, and comprising a hood (14), which is pivotably connected to the base (12) and which has a scale-space cover (50) and scale-space walls (52, 54, 56) and at least one heating element (44), which is effective into the space surrounded by the scale-space walls (52, 54, 56) and which is in electrical contact with power electronics. The invention is characterized in that the hood (14) consists of two separate modules (36, 48), namely an electronics module (36), comprising the heating element (44) and the power electronics, and a mechanical module (48), comprising the scale-space cover (50) and all scale-space walls (52, 54, 56), the mechanical module (48) being rigidly and reversibly coupled to the electronics module (36) in such a way that the heating element (44), which protrudes from the main body (42) of the electronics module (36), which main body is pivotably connected to the base (12) and surrounds the power electronics, protrudes through a corresponding opening (58) in the rear scale-space wall (56).

    摘要： The invention relates to a method for functionally testing a measuring device for gravimetrically determining material moisture (10), comprising a weighing apparatus and a heating device (60) for heating a measurement medium (50) positioned on a load receiving means (40), comprising the steps of: - positioning the measurement medium (50) on the load receiving means (40), - heating the measurement medium (50) according to a predefined monotonous heating profile, - determining a weight profile of the measurement medium (50) by measuring at least two weight values at different times, at least one of which is measured during the heating step, - extracting a test value from the determined weight profile, - comparing the test value with a stored reference value. The invention is distinguished by the fact that the weight profile is determined by measuring a plurality of weight values at different times during the heating step and the magnitude of the gradient of a straight line segment representative of a characteristic test area (160) of the weight profile is determined as the test value and by the fact that the reference value is a gradient value which is expected and stored for the measurement medium.
