First use
Checking the distance measurer and the product contents
- Take the distance measurer and the battery out of the packaging.
- Check whether the distance measurer or the battery exhibit damage.
If this is the case, do not use the distance measurer. Contact the manufacturer at the service address specified on the warranty card. - Check to make sure that the delivery is complete (see fig. A).
Inserting the battery
- Open the battery compartment cover 22 on the back of the distance measurer (see step 1 in fig. C).
-
Push the battery connector clip 23 onto the poles of the battery 9 (see step 2 in fig. C).
-
Insert the battery in the battery compartment and close the battery compartment cover.

If the battery icon 📋 14 appears on the display, the battery has to be changed.
Switching the distance measurer on and off
- Push the button 5 to switch the distance measurer on.
- Push and hold the ⏻ button for about 2 seconds to switch the distance measurer off.
- After 60 seconds without input, the distance measurer will automatically switch off.
Changing the measurement reference
The distance measurement can be calculated from two points (front or back side of the device). Briefly push the ⏻ button 5, to change the measurement reference 3. The indicator for the measurement reference 20 displays the selected measurement reference.
Preventing measurement errors
Observe the following points to avoid measurement errors:
- It is not possible to measure distances through glass.
- It is not possible to measure distances through noise-absorbing objects such as curtains.
- Depending on the surface composition of the opposite object, measurement errors may occur.
- The distance measurer must be positioned at 90° relative to the opposite surface. Use the level 8 for this.
- Strong wind may cause measurement errors.
- Objects between the measurement object and the distance measurer can impair the measurement accuracy.
- Measurement errors may occur when measuring distances that fall under the maximum distance measuring range (measuring range: 0.6 – 16 m or 2 – 52 ft).
If the value measured is outside of the specified range, the error message “Err” will appear on the top line of the display.

- If different parameters are added (e.g. length plus area), the plus sign (+) 12 will be ignored and the display will show the result from the previous measurement.
- In the event of measurements near other ultrasonic devices or high frequency tones, switch the noise source(s) off during the measurement.
- Temperatures and humidity may affect the measurement accuracy. The temperature of the distance measurer should correspond with the ambient temperature, particularly with measurements of larger
distances between 12 m and 16 m (39 ft to 52 ft). The relative humidity should be above 48 % and the area being measured should amount to at least 3 × 3 m.
- Measurement errors may occur when measuring distances in narrow corridors or passages. The greater the distance, the wider the area that must be kept unobstructed in the direction of the measurement. The laser pointer 1 is only activated to mark the opposing point of measurement during the actual measurement, that is, as long as the READ button 11 is pressed down. Observe the following figures.


a = area to keep free
