3.5 Automatic alignment and surveillance
Using the PR 300-HV2S and the PRA 300, a single person can align the laser plane automatically with a certain point
with great accuracy. The tool detects the applicable alignment (horizontal, vertical or inclined) automatically and uses
the automatic alignment function accordingly (horizontal with the PRA 90 plus inclination) or automatic alignment with
subsequent monitoring of the plane (vertical). With the aid of the PRA 300, the surveillance function checks alignment
of the laser plane at regular intervals in order to avoid possible deviations due to temperature fluctuations, wind or
similar. The surveillance function can be deactivated.
3.6 Digital inclination display with patented automatic electronic inclination alignment
The digital inclination display is capable of indicating an inclination of up to 25% when the PR 300-HV2S is operating in
inclined mode. This makes it possible to set out and check slopes without having to make any calculations. Automatic
electronic inclination alignment allows optimum inclination accuracy.
3.7 Shock warning
The shock warning function is activated two minutes after the tool has leveled itself after switching on. If a key is
pressed within these two minutes, the two-minute delay begins again. The tool switches to warning mode if it is
brought out of level while in operation (due to vibration or an impact); all LEDs begin to blink and the laser switches
off (the head stops rotating).
3.8 Automatic cut-out
The laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range (±16° X-axis, ±10°
Y-axis) or if movement is blocked mechanically.
The tool can be set up on a tripod with a 5/8" thread or stood directly on some other steady surface (free of vibration).
When automatic leveling is activated for one or both axes, the built-in servo system ensures that the specified accuracy
is maintained. The tool switches itself off when automatic leveling cannot be achieved (tool set up outside its leveling
range or physical impediment of the mechanism) or when knocked off level (see "Shock warning" section).
NOTE
If the correct level cannot be achieved, the laser switches itself off and all LEDs blink.
