Typical measurement update is 1 second. (Using the software the update time
can be adjusted as fast as 0.5 second).
Things to Remember
The rubber portion of the tip accessories (cone tip, funnel tip, FPM wheel)
may become hot and may wear out prematurely at high speeds.
Press the tachometer firmly on the moving material when using the wheel.
Do not go beyond 300mm /min.
Non-Contact Measurements
Example: Measuring the RPM of a motor shaft.
Using a piece of reflective tape to measure the rotation of the motor shaft.
• Do not use this method for shafts smaller
than the reflective tape. The tape should
be at least the same size as the laser
beam.
• Do not use this method for shafts that are
shiny. This may trigger the tachometer to
have false readings.
• Remove water and oil from the shaft prior
to attaching the reflective tape.
• The unit selector switch is turned to
Non-contact RPM.
The Unit Selector Switch becomes
inactive when the USB cable is
attached from a computer.
The laser beam opening is pointed towards the
position of the reflective tape.
Effective distance is 50mm -1.5m (2 inches - 14 ft)
from the laser beam outlet.
