Inserting bbatteries: 1 To open the battery compartment, push the battery cover down. 2 Insert batteries (2x 1.5 V type AAA). Observe the polarity! 3 To close the battery compartment, push the battery cover back on.

• Unit of rotational speed: rpm, rps

• Auto off function: OFF, ON (instrument switches off automatically if no key is pressed for 10 minutes) 1 When switching the instrument on, press and hold until and appear on the display (configuration mode). - The adjustable function is displayed. The current setting flashes. 2 Press ( ) several times until the desired setting flashes. 3 Press ( ) to confirm the input. 4 Repeat steps 2 and 3 for all functions. - The instrument changes to measuring mode.15 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.

Switching tthe iinstrument oon: i Press . - Measuring mode is opened.

Changing tthe ddisplay vvie w/setting tthe nnumber oof bblades: 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 . i Press several times until the desired view appears.

Measuring Warning! Danger of injury from rotating parts! i Keep to the safe distances and comply with the protective measures stipulated by the manufacturer. i Press and hold .

rpm or rps flashes in the display as soon as useful measuring signals are available. The light spot marks the centre of the measuring surface. - When measurement has been completed (release ), the instrument changes to the Hold display view and the reading is held.

Switching tthe iinstrument ooff: i Press and hold until the display goes out.Maintaining the product
