Very easy to use single counters thanks to the decimal keyboard and the set of LED indicators. Main counter with 1 or 2 presets over 6 digits with sign. General total over 8 digits. Integrated auxiliary cycle counter (or tachymeter) and time counter. Impulse scaling factor. "Floating preliminary" and "permanent comparison of 2 preset" functions. Many programmable counter modes: adding, subtracting, bi-directional, sum or difference, etc.
