Frequently Asked Questions - LaserRangeMaster T3 Laserliner

How to turn on the LaserRangeMaster T3?

Press the ON/OFF button (center button) for 2 seconds. The laser turns on and the device starts continuous measurement.

How to change the batteries?

Open the battery compartment at the back and insert 2 AAA (LR03) batteries respecting polarity. Use high-quality brand batteries.

What does error code Err252 mean?

Err252 indicates that the ambient temperature is too high (> 40°C). Let the device cool down before use.

What is the distance measurement accuracy?

Typical accuracy is ± 2 mm over a distance up to 10 m under good conditions (reflective surface, ambient temperature). Beyond that, the deviation can reach ± 0.2 mm/m.

Can I use the device outdoors?

Yes, but outdoor use is limited. Avoid strong sunlight, rain, fog or snow which can distort measurements. The maximum range is 30 m indoors.

How to measure an area with the distance meter?

Activate the Area function (S button). Measure the length then the width. The device automatically calculates the area displayed in m².

How to use the Pythagoras function?

The Pythagoras 1 function allows measuring an inaccessible height by taking two measurements. Activate it via the DIST button, follow the on-screen instructions for base and hypotenuse measurements.

How to change the measurement unit?

Press the Unit button (labeled m/ft/inch/_'_'') repeatedly to switch between units: meters (m), feet (ft), inches (inch) or fractional feet/inches.

What to do if the device does not turn on?

First check the batteries: replace them if necessary. Make sure the polarity is correct. If the problem persists, contact customer service.

How to clean the LaserRangeMaster T3?

Use a slightly damp soft cloth. Never use solvents, abrasive products or detergents. Avoid water entering the housing.

General safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• The measuring tools and accessories are not toys. Keep out of reach of children.
• Modifications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specifications.
• Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
• The device must no longer be used if one or more of its functions fail or the battery charge is weak.
• Please ensure compliance with the safety regulations set out by local and national authorities with regard to the correct and proper use of the device.

Safety instructions

Using class 2 lasers

Laser radiation! Do not stare into the beam! Class 2 laser < 1 mW · 650 nm EN 60825-1:2014/AC:2017

• Attention: Do not look into the direct or reflected beam.
• Do not point the laser beam towards persons.
• If a person's eyes are exposed to class 2 laser radiation, they should shut their eyes and immediately move away from the beam.
• Tampering with (making changes to) the laser device is not permitted.
• Under no circumstances should optical instruments (magnifying glass, microscope, binoculars)

Safety instructions

Dealing with electromagnetic radiation

• The measuring device complies with electromagnetic compatibility regulations and limit values in accordance with EMC-Directive 2014/30/EU.
• Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.

Important notices

• The laser points to the location that will be measured.
  No objects may get into the laser's line of measurement.
• The device compensates the measurement for different room temperatures. Therefore allow the device a brief adaptation period when changing locations with large temperature differences.
• The device is only conditionally useable in outdoor areas and cannot be used in strong sunlight.
• The measurement results of outdoor measurements may be influenced or falsified by rain, fog and snow.
• In unfavourable conditions, e.g. with poorly reflecting surfaces, the maximum deviation may be greater than 3 mm.
• Carpeting, upholstery or curtains will not reflect the laser optimally. Measure to flat surfaces.
• Measurements made through glass (window panes) can falsify measurement results.
• An energy-saving function switches the device off automatically.
• Clean with a soft cloth. Water may not be allowed to penetrate the housing.
