Frequently Asked Questions - LaserRange-Master Gi4 Mini Laserliner

How to turn on the device and take a first measurement?

Briefly press the ON/measure button to turn on the instrument. The laser activates. Aim at the target and press again to take the measurement. The distance is displayed. To turn off, press and hold the button for 2 seconds.

What is the accuracy of the rangefinder?

The typical accuracy is ± 2 mm for distances up to 10 m on a highly reflective surface at room temperature. Beyond that or in difficult conditions (strong sunlight, matte surfaces), the deviation can reach ± 0.2 mm/m.

Can the device be used outdoors?

Outdoor use is limited. The laser beam is hardly visible in bright sunlight. Rain, fog, and snow can distort measurements. The measuring range is specified for a maximum indoor illumination of 5000 lux.

How to change the measurement reference (front/back)?

The device allows you to choose between measuring from the front or back. Press the DIST and C buttons simultaneously to switch between the two reference planes. The corresponding icon is displayed on the screen.

What do the error codes mean?

Common error codes: Err08 (incorrect Pythagoras measurement), Err10 (low batteries/battery), Err15 (distance out of range), Err16 (signal too weak). Refer to the manual for the full list.

How to use the continuous measurement function (min/max)?

From the measurement screen, press the function button twice until the min/max icon appears. The laser stays on. Move the device toward the target; the screen displays the minimum (min), maximum (max), and current distance. Press DIST to stop.

How to clean the device?

Use a slightly damp soft cloth. Do not use cleaning agents, solvents, or abrasives. Make sure no water enters the housing. Remove the battery for prolonged storage.

Is the device waterproof?

The protection rating is IP 40: protected against solid bodies larger than 1 mm, but not protected against water. Avoid moisture and rain.

How to recharge the battery?

Connect the supplied USB cable to a standard power adapter (5 V / ≥ 1000 mA). During charging, the screen shows an animated battery symbol. Charging is complete when all bars are full and fixed. Only use suitable chargers.

How to access the memory and clear values?

Press the function button six times to enter memory mode. Use DIST to scroll through the 19 slots. To clear a value, press C. In normal mode, a brief press of C clears the last measurement.

Completely read through the operating instructions, the "Warranty and Additional Information" booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. These documents must be kept in a safe place and passed on together with the product.

Intended use

This laser rangefinder provides precise determination of lengths, areas and volumes, and is perfect for acquiring room sizes and calculating material quantities. Heights and distances can be determined indirectly using the Pythagoras angle function.

General safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• Keep the measuring device away from children.

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, the battery charge is weak, or the housing has been damaged.

- When using the device outdoors, make sure that the weather conditions are appropriate and/or that suitable protection measures are taken.

- 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 · 515 nm

EN 60825-1:2014/A11:2021 / EN 50689:2021

• 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.
• The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating fields.

Green laser technology

Approx. 6 times brighter than a typical red laser with 630 - 660 nm

Use of lithium-ion battery

• The battery may be charged only with the enclosed USB charging cable on a standard commercial USB power supply unit (5V/>= 1000mA). Using any other power pack/charger will invalidate the warranty.
• Use the power supply/charger unit only in closed rooms; do not expose to moisture or rain otherwise risk of electric shock.
• Charge the device's battery completely prior to use.
• After the charging cable has been plugged in, a battery symbol with increasing bars appears in the display for the entire duration of the charging process. As soon as the charging process is complete, a battery symbol with a full number of bars appears.

The device has a replaceable battery. Contact your distributor or the UMAREX-LASERLINER service department.

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.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.

Calibration

The measuring device should be calibrated and tested on a regular basis to ensure it is accurate and working properly. We recommend the measuring device is calibrated every year. If necessary, contact your distributor or the UMAREX-LASERLINER service department.
