3.1.3 Measure rpm
1. Put the switch to RPM position to measure rpm or
TOT to measure the number of revolutions.
2. Put a small piece of reective tape (approx
1x1 cm) on the rotating object to be measured.
3. Hold the laser tachometer at right angles at a
maximum of 10 cm from the tape.
4. Press in and hold the measuring button on the
side of the instrument. Aim the laser beam at the
object and the reective tape. The display will
light up after 1-2 seconds.
5. Hold in the measuring button during the whole
measuring procedure. The instrument is turned
o󰀨 when the measuring button is released.
3.1.4 Read the last, highest and lowest
values
The instrument will automatically save the last,
highest and lowest readings for a measurement (i.e.
as long as the measuring button is depressed). Press
in and hold the memory button (MEM) in order to see
the saved readings. The reading is shown on the
display after 1-2 seconds. Reading indicated with:
• Press once to see the last reading: ”LA”.
• Press twice to see the highest reading: ”UP”.
• Press 3 times to see the lowest reading: ”dn”.
3.1.5 Change battery in laser tachometer
Replace the batteries when the low battery symbol is
displayed.
1. Open the battery cover by loosening the
recessed head screw that holds it.
2. Remove the old batteries and replace them with
new ones. Use 4x 1.5 volt R6 (AA) batteries.
CAUTION: Insert the batteries the right
way or the instrument can get damaged.
3. Close the battery cover and lock it with the screw.
3.1.6 Maintenance
• Clean the tachometer with a soft, damp rag.
Never use any form of solvent for cleaning.
• Never dip into water or other liquid.
• Do not expose the tachometer to direct sunlight,
high temperature, excessive amounts of dust or
mechanical impact.
• Remove the batteries if the instrument is not
being used for long periods.
• Only let an authorized repair technician open the
laser tachometer.

3.1.1 Safety during use
WARNING: Read these safety instruc-
tions before you use the laser tachom-
eter.
• Class 1 laser product.
• Be careful when the laser beam is on. Do not look
straight into the beam. Do not aim the beam in the
direction of the eyes of other persons or animals.
• Do not aim the laser beam towards polished
surfaces which can reect the beam into eyes.
• Do not aim the laser beam at explosive gases.
3.1.2 Remember when measuring
• The reecting surface must be smaller than the
non-reecting surface.
• If the object to be measured is shiny, cover the
measured surface with black tape or paint it black
before the reective tape is a󰀩xed.
• Clean the surface before you a󰀩x the tape.
• During measure at low speed, you can get a more
precise reading by fastening more pieces of tape
evenly distributed around the object to be
measured. Divide the read value with the number
of tape pieces to get the real rpm.
