Operation manual for the ST-4000 LED stroboscope: operation panel, flash rate and brightness settings, external trigger mode, and full specifications.
The ST-4000 LED Stroboscope Operation Manual describes a portable, light-weight stroboscope with gun-trigger light activation that uses 21 super bright CREE high powered LED lamps. It is designed for speed and frequency measurements in motion and vibration analysis, and the text lists predictive and preventive maintenance uses such as motors, shafts, fans, cams, gear teeth, belt inspections and printing, packaging, textile, automotive, cable and other industrial work.
The manual gives safety warnings, names the keys on the operation panel and the items on the home display, and explains the menu settings for brightness, external sensor, automatic shutdown and Hz/FPM units. It then covers flash rate setting in internal mode, the x2 and 1/2 keys, flash duration (Brgt) adjustment, external trigger mode wiring, and closes with specifications and included accessories. Every page carries a GlobalTestSupply distributor watermark; no manufacturer is named.
