The PCE-DSX 100 stroboscope is a convenient tool designed for measuring the speed of objects within a range of 60 to 20,000 RPM. It is particularly useful for inspecting objects with periodic movements and identifying faults. The stroboscope facilitates precise measurements through both fine and coarse adjustment options. Fine adjustment allows for small speed changes: +0.1 RPM for speeds below 1000 RPM and +1 RPM for speeds above 1000 RPM. The coarse setting allows for larger adjustments: +10 RPM for speeds below 1000 RPM and +100 RPM for speeds above 1000 RPM.
