3.3 Instelling van Meetverwysingspunt

The device allows you to choose the measurement reference point:

Front Reference: Measurements are taken from the front edge of the device. The device's length is not included in the result.
Rear Reference: Measurements are taken from the rear edge of the device. The device's length is included in the result.

To switch between reference points, short press the V/H button. An icon on the display will indicate the currently selected reference point.

3.4 Verandering van meeteenhede

The LT-40 supports meters (m), inches (in), and feet (ft).

To cycle through units, long press the V/H knoppie. Die eenheid wat op die skerm vertoon word, sal dienooreenkomstig verander.

4. Operation - Measurement Modes

The LT-40 offers various measurement functions. To switch between modes, short press the V/H button until the desired mode icon appears on the display.

4.1 Enkelmeting

Measures the direct distance between the device and a target.

Skakel die toestel aan.
Point the laser at the desired target.
Short press the main button to emit the laser.
Short press the main button again to take the measurement. The result will be displayed instantly.
