Z-Axis Calibration (GRL 500 HV)

– Mark a vertical line on the wall using a plumb line.
– Mount the measuring tool in the vertical position on a tri-
pod 63 (accessory).
– Place the tripod 5–10 m in front of the wall.
– Switch the measuring tool on.
– Simultaneously press the calibration
button 25 and the slope button 18 for
approx. 2 s.
The symbol for calibrating the Z-axis is
shown on the display.
– Align the tripod so that the laser beam crosses the vertical
line on the wall.
