· Auto off function: OFF, ON (instrument switches off automatically if no key is

pressed for 10 minutes)

1When switching the instrument on, press and hold until

and appear on the display (configuration mode).

- The adjustable function is displayed. The current setting

flashes.

2Press ( ) several times until the desired setting flashes.

3Press ( ) to confirm the input.

4Repeat steps 2and 3for all functions.

- The instrument changes to measuring mode.

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.

²Switching tthe iinstrument oon:

iPress .

- Measuring mode is opened.

²Switching tthe ddisplay llight oon:

The instrument is switched on.

iPress .

- The display light goes out automatically if no key is

pressed for 10 seconds.

²Changing tthe ddisplay vview/setting tthe nnumber oofbblades:

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)

Adjustable views/setting the number of blades

·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 .

iPress several times until the desired view appears.
