Operational Notes (Stroboscope)
| Preparation | Determine the range switch to “1000 RPM” or “10,000 RPM”; position the strobe light toward the target. |
| Checking Speed | Adjust the flashing frequency until the target appears stationary; be aware of harmonic multiples. |
| Checking Motion | For motion analysis, slightly reduce or increase the flash rate to create a slow‑motion visual effect. |
