Instrument Set-up

Overview

The safety instructions and the user manual should be read through carefully before the product is used for the first time. The person responsible for the product must ensure that all users understand these directions and adhere to them.

Display

The device display shows:

• Battery: Battery status indicator (e.g., ?).
• Area / Volume / Pythagoras(2-Point/3-Point): Indicators for measurement modes.
• Measuring Reference: Indicates the current measurement reference point.
• Pythagoras: Indicator for Pythagoras measurement mode.
• Info: Indicator for information or error messages.
• Main line: Displays the primary measurement result.
• Units: Displays the current measurement units (e.g., m, ft).

The device itself has the following controls:

• On/ Measure / Continuous measuring button.
• Units / Measuring Reference button.
• Add/Sub button.
• Clear / Off button.
• LASER ON button.

Insert batteries

To insert batteries:

1. Open the battery compartment.
2. Insert two AAA batteries, observing correct polarity (+/-).
3. Close the battery compartment.

Note: Change batteries when the battery symbol is empty.

Operations

Switching ON/OFF

Press the LASER ON button to turn the device ON. The device is turned OFF by pressing the C/OFF button for 5 seconds. If no key is pressed for 120 seconds, the device switches off automatically.

If the info icon ⓘ appears with a number, consult the "Message Codes" section.

Unit setting

Press the UNITS button for 3 seconds to switch between the following units: 0.000 m, 0'00" 1/16, 0 1/16 in, 0.00 ft.

Change Measurement Reference

The system default measurements start at the bottom as a reference point.

1. The device is initially set with the bottom as the reference point.
2. Press the UNITS button to change the reference to the top of the device for measurement.
3. The measurement and the system recover to the initial setting (bottom reference).

Measuring Functions

Measuring single distance

1. Press LASER ON to activate the laser.
2. Aim the active laser at the target.
3. Press LASER ON again to take the measurement. The result (e.g., 59.99 m) is displayed.

Target surfaces: Measuring errors can occur when measuring to colourless liquids, glass, styrofoam, or semi-permeable surfaces, or when aiming at high gloss surfaces. Against dark surfaces, the measuring time increases.

Continuous measuring

1. Press LASER ON for 3 seconds to start continuous measuring.
2. Aim the active laser at the target. The last value measured is displayed.
3. Press LASER ON to stop continuous measuring.

Area

1. Press the appropriate button to select Area mode (indicated by 1x).
2. Aim laser at the first target point.
3. Aim laser at the second target point.
4. The result is shown in the main line and the measured distance above (e.g., 24.352 m²).

Volume

1. Select Volume mode (indicated by 2x).
2. Aim laser at the first target point.
3. Aim laser at the second target point.
4. Aim laser at the third target point.
5. The result is shown in the main line and the measured distance above (e.g., 78.694 m³).

Pythagoras (2-point)

1. Select Pythagoras (2-point) mode (indicated by 3x).
2. Aim laser at the first target point.
3. Aim laser at the second target point, ensuring a 90° angle to the first measurement.
4. The result is shown in the main line and the measured distance above (e.g., 25.286 m).

Pythagoras (3-point)

1. Select Pythagoras (3-point) mode (indicated by 4x).
2. Aim laser at the first target point.
3. Aim laser at the second target point, perpendicular to the measuring surface.
4. Aim laser at the third target point.
5. The result is shown in the main line and the measured distance above (e.g., 26.868 m).

Clear

Press the C/off button to undo the last action.

Addition/Subtraction

1. Measure the first data (e.g., 29.999 m).
2. Press the "+" or "-" button to add or subtract the next measurement from the previous data.
3. Then measure the second data (e.g., 20.000 m).
4. The result is shown in the main line and the measured distance above (e.g., +20.000 m / 49.999 m or -20.000 m / 9.999 m).

Technical Data

*The typical measurement uncertainty of ± 2 mm is valid for measurements on white, diffusive, reflective targets up to 5 m at low ambient light and moderate temperatures. For distances greater than 5 m, the measurement uncertainty could increase additionally by 0.1 mm/m. In unfavourable conditions (such as bright sunlight, targets with poor reflectivity, or high or low temperatures) the measurement uncertainty could further increase up to ± 4 mm for distances below 5 m and additionally by roughly 0.15 mm/m for distances greater than 5 m.

Message Codes
