This document provides instructions and precautions for using the Extech Digital Stroboscope Tachometer. This device is used to measure the speed of moving parts and allows for visual inspection of these parts. The instrument is reliable and safe to use.
The Extech Digital Stroboscope Tachometer is an instrument designed to measure the speed of moving parts such as gears, fans, propellers, centrifuges, and pumps. It utilizes a stop-motion action via a Xenon lamp to allow for the visual inspection of rotating objects by synchronizing the flash rate with the object's speed.
The device features a 4-digit LED display and allows users to select between two power ranges: Model 461830 operates on 110VAC, while Model 461831 operates on 220VAC. Users can adjust the strobe flash rate using coarse and fine knobs to achieve a stationary image of the moving object for accurate RPM measurement.
