Ever had you Laser Receiver Keep Going Off with No Lasers On? and other receiver FAQ’s

Strobe Light

High intensity strobe lights. This is something that crops up once in a while and can slow you down.

Most of the time this is due to high intensity strobe lights on plant such as earthmovers, backhoes and bobcats. It’s something that can effect pretty much every laser receiver out there and can only be resolved by working further away from that machinery or by switching off the strobe.

For the majority of laser receivers your standard rotating orange lights do not create any interference, it’s just limited to some of the newer high intensity ones.  Some strobes can even interfere when out of direct line of site they produce so much electro magnetic interference.

Another common problem is Reflections.

This can affect pretty much all laser receivers, in that they can not only pick up the original laser beam but also a reflected one of glass or other shiny surfaces.  Most of the time the reflected beam will be at a different height to the original so the receiver may pick up two heights as being level.  To stop this problem is pretty easy and that is to make sure that when you set up the laser reflections cannot be bounced back to the receiver.  So for example if on site there is some large glass surfaces, make sure you set up the laser so that when you hold the receiver the glass is behind you and the receiver so cannot reflect onto it.  Some laser come with a quadrant beam shield function which can turn off segments of rotation again which will prevent this situation.

Another source of potential interference when inside is faulting fluorescent lights.

This has come up a few times, many laser receivers will produce intermittent beeps (without even the laser turned on) inside close to a faulting fluorescent light, again this due to a pulsing interference. If you move away from the light all works well again.
