User Manual
■. Introduction
Thank you for purchasing this tachometer from
SUPCO. Please take a few minutes to browse through
this user manual before you begin to operate the meter
to ensure that you are fully familiarized with how best
to operate the meter as accurately and safely as
possible.
The meter is a rotational speed (measured in rpm)
measuring instrument. It is normally used to measure
rotational speed, e.g. of fan blades, impellers, drums
and spindles.
Warning! Keep a safe distance from the
rotating object being measured.
1.1 Precautions safety measures
To get the best service from this meter, please read
this user's manual carefully and observe the detailed
safety precautions strictly.
1.1.1 During use
-1-
1. For reliable measurements it is necessary to use
reflective markers. To apply the reflective markers,
wait until the object to be measured has come to a
standstill.
2. The ideal distance to the measurement object is
between 4” to 16”. During the measurement, always
aim at the reflective marker from an angle of
approximately 30°. This avoids multiple reflections
from the surface.
3. If no reflective marker can be attached, it must be
checked whether the reflective properties of a
reflective point on the measurement object are
sufficient for rpm measurement. In this case, aim at
the measurement object from the vertical, and check
whether a value is displayed. If the measurement
object displays several reflections per revolution, the
number of ventilator vanes must be set (e.g.
reflective ventilator with 5 vanes) in order to obtain
correct rpm measurements.
-2-
4. If the OL symbol is displayed on the LCD, it means
the readings are outside the measuring range.
Please keep within the specified measuring range.
5. Never store the product together with solvents, acids
or other aggressive substances.
1.1.2 Maintaining the product
l Do not measure at a high temperature, high
humidity locations.
l When not using the instrument for a long time,
please remove the battery and avoid storing in
high temperature and high humidity.

■ Operating Instructions
1. Cut out a piece of the reflective marker and attach
it to the rotating object which is under test. And then
start this rotating object. (Make sure to stop the
-7-
rotating object first and then paste the reflective
marker)
2. Press the ON/ OFF key to turn the unit on.
3. Press the key and the LCD will display 0.0.
4. Keep pressing the key, the meter will enter
the measurement state and launch a beam of red
laser. Point the laser towards the rotating objects
affixed with a reflective marker. Adjust the distance
between the instrument and the rotating object to 4”
to 16”. Now, an accurate measurement can be
read.
4. After completing the measurement, release the
key and the LCD will hold the last measured
value.

TACHYMETRE PORTABLE A
INFRAROUGE
INTRODUCTION
Merci d’avoir acheté ce tachymetre portable. Veuillez prendre quelques minutes pour passer
en revue ce manuel d'utilisation. Vous devez vous assurer que vous vous étes entiérement familiarisés
avec l’appareil pour pouvoir l’utiliser sans risque.
Cet instrument mesure la vitesse de rotation
ATTENTION : GARDER UNE DISTANCE DE SECURITE ENTRE L’APPAREIL DE MESURE
ET LA PARTIE EN ROTATION A MESURER
1.1 PRECAUTION D’UTILISATION
Pour avoir la meilleure utilisation de ce tachymeétre, veuillez lire attentivement ce manuel
et respecter scrupuleusement toutes les instructions.
LLL PENDANT L’UTILISATION
LALA
1.1.1.2
LA.L3
1.1.1.4
LslihS
1.1.1.6
Pour effectuer une lecture il est nécessaire d’utiliser un marqueur
réfléchissant. Pour poser le marqueur, il faut attendre que I’ objet soit stabilisé.
La distance idéale pour effectuer une mesure est de 10 4 40 cm. Pendant la
mesure, il faut tenir un angle de 30° pour éviter les multiples réflexions de la
surface réfléchissante.
Si la pose du marqueur n’est pas possible, et que la matiére de l’objet a
mesurer est suffisamment réfléchissante pour faire une mesure tachymeétrie, il
faut faire la mesure bien perpendiculaire. Si l’objet a plusieurs zones
réfléchissantes qui passent devant le tachymeétre, il faudra diviser la mesure
par le nombre de zones (ex : ventilateur 4 5 pales, il faudra diviser la mesure
par 5).
Le symbole OL s’affichera quand la mesure est en dehors de la plage de
mesure de l’appareil.
Quand la batterie est en dessous de la charge minimum nécessaire a
l'utilisation, le symbole ## apparait sur l’écran LCD. II faut done changer la
batterie.
Ne pas stocker 4 proximité de solvants, acides et autres produits agressifs
L,2 BIEN UTILISER CE PRODUIT
1.1.2.1 Ne pas faire des mesures dans des lieux trop chauds et ou trop humides.
1.1.2.2 Si vous n’utilisez pas le produit pendant un long moment, veuillez retirer les piles
et conserver le produit dans un endroit 4 l’écart de la chaleur et de l’humidité.
