An external indicator device presents parameters associated with stimulation therapy generated by a pulse generator, which may be associated with an external or implantable stimulation device. The contone image is halftoned and encoded to generate image data including edge tag data and image data. At the weighing cell, a measured weight value is obtained, and this measured weight value is subsequently interpreted and, based on the interpretation of the measured weight value, the transport device is switched to a different operating mode, which may include reversing the direction of the transport device so as to permit the item to be re-weighed and subsequently discharged from the scale. The software patch is applied on the one or more software components running on an application server node of the second instance of the cluster. By filling the basin with a conductive solution, direct contact between the probe and the sample may be avoided along with the associated variability in contact resistance.
