Abstract
A verification of a pipette results in a release or a warning message. A liquid measuring container () receives the pipette liquid volume (V) to be verified. A loading cell () is connected to the liquid measuring container in a force-transmitting manner. The loading cell outputs a measurement signal (ms) corresponding to the weight force (F) acting thereon. A processing unit () detects and processes the measurement signal (ms), determines a first weight force (G) at time point (t) and determines a second weight force (G) at time point (t). The pipette liquid volume is calculated and the calculated value is assigned to a pipette volume class (K) having a defined class nominal value (VK). The processing unit tests whether or not an absolute value of the volume difference (ΔV) is within a predetermined tolerance value (T) for the assigned pipette volume class. The processing unit outputs the test result.
