7.2.1 Laser safety
WARNING: The optical tachometer is a class 1
laser product. Read the warning instructions
that follow before you use it.
•
Be careful when the laser beam is on.
•
Do not look into the laser beam.
•
Do not point the laser beam at shiny surfaces. It can
make a reflection into your eyes.
•
Do not point the laser beam at the eyes of a person
or animal.
•
Do not point the laser beam at explosive gases.
7.2.2 To measure rpm with tachometer
Attach more than one piece of tape on the surface to get
the accurate result when measuring at low speed. Put
the tape with the same distance between the pieces.

Then divide the read value with the number of tape
pieces to get the accurate rpm.
1. Make sure the area of reflection is smaller than the
area without reflection. If the object to be measured
is shiny. Put black tape or black paint on the
measured surface before the reflection tape is
attached.
2. Clean the surface to be measured before attaching
the reflection tape.
3. Put a small piece of reflection tape (approximately
1x1 cm) on the object to be measured.
4. Put the switch to the RPM position for measuring
rpm or TOT for measuring the number of
revolutions.
