RangeXtender M50 - Laser level Laserliner - Free user manual and instructions

USER MANUAL RangeXtender M50 Laserliner

Intended use This laser receiver is suitable for all green line lasers with an integrated hand receiver mode (GRX-READY technology). It quickly detects laser lines up to a maximum distance of 50 metres. Arrow symbols and a millimetre display inform users of the exact height difference between the laser beam and the marking level.

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. General safety instructions – The device must only be used in accordance with its intended purpose and within the scope of the specications. – The measuring tools and accessories are not toys. Keep out of reach of children. – The structure of the device must not be modied in any way. – Do not expose the device to mechanical stress, extreme temperatures, moisture or signicant vibration. – The device must no longer be used if one or more of its functions fail or the battery charge is weak.RangeXtender M 50

magnetic IP 66 Protection against dust and water – The laser receiver is exceptionally well protected against dust and rain. For many measuring tools, the key to optimum working is magnetic adhesion. This leaves the hands free to complete other tasks. The receiver speeds up response times - rapid detection accelerates work rates. Special product features and functions Risk of pinching! Do not reach into the clamping bracket!

Danger - powerful magnetic elds Powerful magnetic elds can adversely affect persons with active medical implants (e.g. pacemaker) as well as electromechanical devices (e.g. magnetic cards, mechanical clocks, precision mechanics, hard disks). With regard to the effect of powerful magnetic elds on persons, the applicable national stipulations and regulations must be complied with such as BGV B11 §14 „electromagnetic elds“ (occupational health and safety - electromagnetic elds) in the Federal Republic of Germany. To avoid interference/disruption, always keep the implant or device a safe distance of at least 30cm away from the magnet.10

Approximate range: Display with maximum tolerance for rudimentary manual alignment. Free-hand range: Display with larger tolerance for alignment by hand.

Pay attention that the laser lines are not reflected by reflective surfaces. Such reflections can lead to false indications.

Working with the laser receiver Use the laser receiver for levelling over great distances or in very bright conditions. Switch it on with button 4. Set the line laser to hand receiver mode. The laser lines will now pulsate with high frequency, making the laser lines darker. The laser receiver can detect these pulsating laser lines up to a maximum distance of 50 m. Now move the receive field (7) on the laser receiver up and down through the laser lines until the middle LED lights up. Now mark the reference dimension.

Insertion of batteries Open the battery compartment (14) and insert batteries according to the symbols. Be sure to pay attention to polarity. Precision range: Display with smaller tolerance for precision alignment (e.g. levelling staff)12 Laser 40 mm RXM 50 RXM 50 RXM 50

Used with levelling staff The laser receiver can be fitted on measuring staffs with the universal mount. The Flexi measuring staff is always recommended when measuring from floor heights. It also allows you to determine heights directly without any need for calculation. The laser reception range may be reduced if exposed to direct sunlight.

The light intensity of the laser lines is greatest at the centre and diminishes toward the ends. This can reduce the maximum reception range of the laser receiver.
