DIGITAL TACHOMETER
• Class 1 laser product.
• Take care whenever the laser beam is on.
• Do not look straight into the beam. Do not aim the
beam towards anyone else's eyes, either people or
animals.
• Do not aim the laser beam towards polished
surfaces where the beam can be reflected into
someone's eyes.
• Do not aim the laser beam at explosive gases.
• Remember when measuring
• The reflecting surface must be smaller than the non-reflecting surface.
• If the object to be measured is shiny, cover the measured surface with black tape or paint it black before
the reflective tape is affixed.
• Clean the surface before affixing the tape.
• When measuring at low speed, a more precise reading can be obtained by fastening more pieces of
tape evenly distributed around the object being measured. Then divide the read value with the number
of tape pieces to obtain the real rpm.
Measure rpm
1. Put the switch to RPM position for measuring rpm or TOT for measuring the number of revolutions.
2. Put a small piece of reflective tape (approx 1x1 cm) on the rotating object to be measured.
3. Press in and hold the measuring button on the side of the instrument. Aim the measuring beam at the
object and the reflective tape. The display will light up after 1-2 seconds.
4. Hold in the measuring button during the whole measuring procedure. The instrument is turned off
when the measuring button is released.
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.
Measured value Indicated with
First press Last “LA”
Second press Highest “UP”
Third press Lowest “dn”
Change Batteries
The batteries are beginning to be depleted when the low battery symbol is displayed.
1. Open the battery cover by loosening the recessed head screw holding it.
2. Remove the old batteries and replace them with new ones. Use 4x 1.5 volt R6 (AA) batteries.
3. Make sure to insert the batteries the right way round or the instrument can be damaged.
4. Close the battery cover and lock it with the screw.
Care
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.
The tachometer may only be opened by an authorized repair technician.
