The 5 and 8 counting units record up to 999. The last unit without a key on the right is the totalizing unit which records the total number of strokes made on other keys. At 100 increments, the totalizing unit rings a bell. Reset knobs are on each side. Removable tabs provide an area for identification of the classification being counted.
