6.2 Optical tachometer
6.2.1 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.
6.2.2 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.
5. Press and hold the measuring button on the side of
the instrument. Point the measuring laser beam at
the object and the reflection tape. The display
automatically illuminate after 1-2 seconds.
6. Release the measuring button to stop the measuring
procedure.
6.2.3 To read the tachometer values
The tachometer automatically saves the last, highest
and lowest values for the measure while the button is
pressed.
•
Press and hold the memory button (MEM) to see the
saved results. The value is shown on the display
after 1-2 seconds.
a) The first push on the memory button shows the
last value, identified with "LA" on the display.
b) The second push on the memory button shows
the highest value, identified with "UP" on the
display.
c) The third push on the memory button shows the
lowest value, identified with "DN" on the display.
6.2.4 Maintenance of the tachometer
•
Clean the tachometer with a soft, moist cloth.
•
Do not use solvent for cleaning.
•
Do not put the tachometer into water or other liquids.
•
Keep the tachometer from sunlight, high
temperature and dirt.
•
Do not cause mechanical chock to the tachometer.
•
Remove the batteries if the tachometer is not used
for long periods.
