INTRODUCTUCTION
Please read 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 measuring instrument. It is normally used to measure rotational
speed, e.g. of impellers, drums and spindles.
Warning! Keep to a safe distance from the detected objects! Danger of injury from rotating
parts!
Warning! Do not point laser directly at the eyes or a reflective surface that shines the laser
into the eyes.
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.
During use
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 measured object is between 10 and 40 cm. During the measurement,
always aim at the reflective marker from an angle of approx.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 measured object are sufficient for rpm measurement. In this case, aim
at the measured object from the vertical, and check whether a value is displayed. If the measured
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 measurement.
4. If the OL symbol is shown on the LCD, it means the reading is outside the measuring range. Please
keep to the permitted measuring range.
5. Never store the product together with solvents, acids or other aggressive substances.
6. When the battery voltage is low, the symbol will show on the LCD indicating that the battery
needs to be replaced with a new one.
