1. GENERAL INSTRUCTIONS
Thank you for purchasing the Digital Tachometer. This meter is for measuring
rotational speed. It is more commonly used by engineers and operators of all
types of rotating plane and machinery across a wide range of industries involving
motors, pumps, compressors and hydraulic. This meter can also be used to
measure the speed of anything that requires a stable or regular rotation such as
a grinding wheel or fan.
Using a precise red LED light source (laser beam) together with a reflective strip,
non-contact measurements can be made safely up to 40cm (15 3/4”) from the
target.
1.1. Precautionary safety measures
To get the best service from this meter, please read this manual carefully and
observe the detailed safety precautions strictly.
Warning!
• Keep a safe distance from the objects being measured!
• Danger of injury from rotating parts!
• The Class II laser beam can potentially cause severe damage
to eyes. Never look directly into the laser beam or point the
laser beam at people either directly or indirectly through reflective surfaces.
1.2. During use
• 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.
• The ideal distance to the measurement object is between 10 to 40cm. During
the measurement, always aim at the reflective marker from an angle of
approx. 30°. This avoids multiple reflections from the surface.

Non-Contact Digital Tachometer
• 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.
• If the ‘OL’ symbol appears on the LCD, it means the reading is outside the
measuring range. Please keep to the permitted measuring range.
• NEVER store the product together with solvents, acids or other aggressive
substances.
• When the battery voltage is under a sufficient operation level, the symbol
will show on the LCD. The batteries will need to be replaced with new.
1.3. Maintaining the product
• DO NOT measure at a high temperature, high humidity places.
• When not using the instrument for a long time, please remove the batteries
and avoid storing in high temperature and high humidity.

4. Operation Instruction
1. Before you start to use the meter cut out a part of the reflective marker and
attach it to the object which is under test. Then start this rotating object.
(Make sure to stop the rotating object before attaching the reflective marker).
4.1. Key
1. First remove the meters protective sensor cover.
2. Press the key to turn the power ‘ON’.
3. The LCD will display ‘‘00..00’’as the current value and ‘‘rrppss’’(rotations per second)
by default.
4. Measuring: Keep pressing the key to activate the laser beam.
Warning!
DO NOT look directly into the red laser beam or point it at other
peoples eyes.
5. Line the laser beam up to the position where the rotating objects affixed with
a reflective marker and maintain the fixed location. Adjust the distance
between the instrument and rotating body to 10 to 40cm, the distance is
based on the reliable and stable value which can be read by the instrument.
At this point you can read the speed of the rotating body.
6. Once the reading has become stable release the key and the LCD will
maintain the value last measured by displaying the ‘HOLD’ symbol.
NNOOTTEE::There is no key for power off. When the meter is not used for 2 minutes
the meter will automatically shutdown.
4.2. Unit key
This key sets the type of rotary speed required for testing.
1. When the meter is switched ‘on’ p
ress the UUNNIITTkey to change between the 2
speed type settings available for measuring. These units are:
rrppss= revolutions per second (Default) and rrppmm= revolutions per minute.
2. BBaacckklliigghhttffuunnccttiioonn::By holding down on the
UUNNIITT
key for 2 seconds the back
light will be turned ‘on’. Press the key
UUNNIITT
key for 2 seconds again and the
back light will be turned ‘off ’.
If the back light is not turned off within 60 sec. it will turn off automatically.
This will save battery power.
