Frequently Asked Questions - VTLD100 VELLEMAN

How to replace the batteries of the Velleman VTLD100?

Open the compartment on the back of the device and insert 2 AAA batteries respecting the polarities (+/-). Close carefully.

What is the maximum measuring range?

The maximum range is 100 meters. However, in strong sunlight or on highly reflective surfaces, the range may be reduced.

How to use the indirect measurement (Pythagoras) function?

Press the 'Pythagoras' button to activate the mode. Follow the on-screen instructions: first measure the horizontal distance, then the oblique distance. The distance meter calculates the height automatically.

What to do if the device does not turn on?

Check the battery status: if they are worn out, replace them with new ones. Also make sure the contacts are not corroded.

How to switch from meters to feet?

Press and hold the 'Unit' button to toggle between meters (m), feet (ft) and inches (in). The selected unit is displayed on the screen.

Is the distance meter waterproof?

No, the VTLD100 is not waterproof. Avoid exposing it to water or excessive humidity. Store it in its case after use.

How to clean the optics of the distance meter?

Use a soft, dry cloth to wipe the lens. Avoid chemical or abrasive products that could scratch the surface.

Can I use the distance meter outdoors?

Yes, it is designed for indoor and outdoor use. However, direct sunlight may reduce range and accuracy.

How to clear previous measurements?

Press the 'Clear' (or 'C') button to clear the last measurement. To clear all values, turn the device off and then on again.

What does the 'Err' error on the screen mean?

The 'Err' error appears if the measurement is out of range or the beam is interrupted. Check that the target is clear and nothing obstructs the laser.

6. Measuring conditions

Measuring range

• The measuring range is limited to 50m.
- In dark environments or at night this range may increase.
- In very light environments or when a surface has very poor reflective properties, use a target plate.

Target surfaces

• Measuring errors will occur when pointing at colourless liquids (e.g. water) or glass, Styrofoam or similar semi-transparent surfaces.
• Aiming at very shiny objects will deflect the laser beam which will lead to errors.
• Measuring towards non-reflective dark surfaces may increase the measuring time.
• Do not aim the meter directly into the sun or other bright light source.
