> Select RPM value with the highest probability.
> Tap SAVE if selected RPM value is accurate.
If necessary, tap STROBE to verify the RPM.
Keyphasor — the laser-trigger sensor is used to measure RPM. The sensor detects the
l
signals optically. A laser beam is emitted from the sensor and strikes a measure mark on
the rotating shaft. The measure mark can amplify light (e.g. reflective foil ) or attenuate
light (e.g. a black, high contrast line on a light-colored surface). Each time the sensor
detects a difference in brightness, it sends an electric impulse. The device calculates the
shaft RPM based on the repeat rate of the pulses.
Note:The reference measure point must be assigned a speed task and the laser-
trigger sensor (VIB 6.631).
