FEATURES
It is used the microcomputer (CPU) technique and junction laser technique for one instrument
combine PHOTO TACH. (RPM) &CONTACT TACH (RPM, m/min).
Wide measuring range and high resolution.
Yellow green backlight makes sure that tachometer can work normally in any light circum-
stance.
The last displayed value/max. Value/min. Value maybe automatically stored in memory and 96s
of measured value continuously. So this makes customers collected and recorded data. (The
tachometer starts to store the data measured after which is renovation for three times).
The tachometer can be connected 6V direct current stable voltage power in favor of using for
long time.
Low battery voltage indication.
Contact part and photo part can be switched value at any time.
New surface speed sensor with flute vials to measure speed and length of wire, cable and rope
conveniently.
The instrument is delicate and rugged. It uses the durable, long-lasting components and a strong,
light weight ABS plastic housing. The comfortably in either hand.

Memory call button operation
A readout (the max value, min value, last value) obtained immediately before turning off the
MEATURING BUTTON is automatically memorized.
For example, please ref. following figure. That memorized value can be displayed on the indicator
by turn once depressing the memory button. The symbol “UP” represents the MAX.
Value and “DN” the MIN. Value, “LA” the Last Value.
Battery replacement
When it is necessary to replace the battery(battery voltage less tan approx.4.5V), will appear
on the display.
Slide the battery cover away from the instrument and remove the battery.
Install the batteries into the case permanent damage to the circuit may result form incorrect
installation.

Reminds
Reflective mark: cut and peel adhesive tape provided into approx. 12mm (0.5”) squares and
apply one square to each rotation shaft. The non-reflective area must always be greater than the
reflective area. If the shaft is normally reflective, it must be covered with black tape or black
paint before attaching reflective tape. Shaft surface must be clean and smooth before applying
reflective tape.
Very low RPM measurement: as if is easy to get high resolution. If measuring the very low
RPM values, suggest user to attach more “reflective marks” averagely. Then divide the reading
shown by the number of “reflective marks” to get the real RPM.
Contact tachometer parts include large taper, small taper and pillar, large taper and pillar rubber
part is suitable to low speed and but the small high speed.
If the instrument is not to be used for any extended period, remove batteries.

MEASURING PROCEDURE
Photo measurmnent
Apply a reflective mark to the object being measured. Slide the function switch to “rpm photo”
position.
Depress the MEASURE BUTTON and align the visible light beam with the applied target. Verify
that the MONITOR INDICATOR lights when the target aligns with the beam.
Contact tach measurement
Slide the FUNCTION SWITCH to “rpm contact” position. Install the proper RPM ADAPTER
on the SHAFT.
Depress the MEASURING BUTTON and lightly pressing the RPM ADAPTER against the
center hole of rotating shaft. Be certain to keep alignment straight. Release the MEASURING
BUTTON when the display reading stabilizes.
Surface speed measurement
Slide the FUNCTION SWITCH to “m/min contact” position. Install the SURFACE SPEED
WHEEL on the SHAFT instead of the RPM ADAPTER.
Depress the MEASURING BUTTON and simply attaching the SURFACE SPEED WHEEL to
the detector. Release the MEASURING BUTTON when the display reading stabilizes.

Note: Because of the difference between the girth of outer surface and inner flute of line speed
sensor. For contact line speed or length measurement, the displaying result is correct when outer
surface of the sensor contacts with the measured object contact and but when inner flute of the
sensor and the measured object, that the reading multiply 0.9 is the real result (eg.: measure wire,
cable and rope etc.)

TACHYMÈTRE NUMÉRIQUE
MOD. 1760/TC2
DESCRIPTION
Cet appareil réunit la technologie du micro-ordinateur (unité centrale) et celle de la diode laser
et fonctionne à la fois comme TACHYMÈTRE OPTIQUE (r/min) et comme TACHYMÈTRE
CONTACT (r/min, m/min).
Plage de mesure étendue et haute résolution.
Le rétroéclairage jaune/vert permet d’utiliser facilement le tachymètre dans toutes les conditions
d’éclairage.
La dernière valeur affichée, la valeur minimale et la valeur maximale sont automatiquement mémo-
risées à chaque mesure. Pour visualiser les données enregistrées, appuyer sur la touche « MEM ».
Le tachymètre peut être directement branché au secteur (6 V, stable) et donc être utilisé pendant de
longs intervalles de temps.
Indicateur des piles déchargées.
Il est possible de passer du mode « contact » au mode « optique » à tout moment.
Nouveau capteur de vitesse de surface avec roue à gorge pour mesurer facilement la vitesse et la
longueur de fils, câbles et cordes.
L’appareil est précis et robuste. Il est fabriqué avec des composants solides longue durée et un corps en
plastique ABS léger. Il peut être manipulé indifféremment de la main droite ou de la main gauche.
