Press this key briey. This symbol is displayed. Press this key to take the three lines
measurement and then the volume value will be displayed in the main display area and the third line
measured value is displayed in the auxiliary area.
In the course of using the instruments, information as below may be displayed on the screen:
Pythagorean measurement is used in the condition that the objective needing to be measured is cove-
red or has no effective reecting surface and can’t be measured directly. The accurate measured result
can be got only when the laser beam and measured goal are at the right angle.
Press this key briey, this symbol is displayed in the screen. According to the on-screen
prompts, press to take right angle edge - right angle, or bevel edge - right angle edge
operation then the instrument will automatically realize Pythagorean operation, the result is displayed
in the main display area.
•When measuring in Pythagorean measurement mode, right-angle edge length must be less than the
length of the hypotenuse, otherwise the equipment will report mention information.
• Under the Pythagorean measurement mode, make sure to start the measurement from the same
starting point. In hypotenuse - right angle edge model, it is also necessary to ensure that right-angle
side is perpendicular to the measured surface.
