2 Design and Function

The LV12 is an automatic feeder for capsules, tablets or small electronic and mechanical
components. Large weighing series are radically simplified. The LV12 is therefore especially suitable
for statistical quality control (SQC). Usually the LV12 is remotely controlled by commands over a
serial interface (RS232 or USB), but the system can also be controlled manually using push buttons.
The LV12 delivers a single part to the balance and then stops automatically. After receiving the appro-
priate command from the weighing instrument, the device delivers the next part. This process can be
stopped at any time by a command. At the end of a sample, the feeder plate can be emptied or the
feeder waits for the command for a further sample.
