Working with the laser receiver GRX
Use the laser receiver GRX for levelling over longer distances
or when the laser lines are no longer visible. Switch on with
button F; control lamp G will light up.
Line lasers:
GRX 30:
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 30 m. Minimum distance from the
laser device about 3 m.
Now move the receiver field (B) of the laser receiver through
the laser lines upwards and downwards (horizontal laser line)
and/or sideways (vertical laser line) until the centre LED
lights up. Now mark the horizontal and/or vertical reference
dimension.
