Using the product
For reliable measurements it is necessary to use reflective
markers. To apply the reflective marker, wait until the object to
be measured has come to a standstill.
The ideal distance to the measurement 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.
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, (e.g. reflective
ventilator with 5 vanes), the number of the impulses per
revolution (e.g. number of ventilator vanes) must be entered
into the instrument (see below) in order to obtain correct rpm
measurements.

As an alternative to entering the impulses per revolution,
the setting NO.1 can be selected and the rpm calculated
manually from the measurement value (measurement value
divided by impulse/number of vanes)

· Hold: Readings are held.
· Max: Maximum values since the start of the last measurement.
· Min: Minimum values since the start of the last measurement.
· NO.: Set the number of blades. Change the value with
Press
several times until the desired view appears.
