1. Calculate two sides of a right angle triangle

Press the multi-function button three times to enter pythagorean 
mode. Follow the instructions displayed on the screen as follows:
a) Press the read button to measure the length (a) of the hypotenuse 
and tilt angle.
b) Length (x) will be calculated automatically with results shown on 
the display screen.

Pythagoras measurement
To calculate the unilateral distance of a triangle pythagorean mode 
can be used. When taking measurements of the triangle, ensure the 
length of the right side is shorter than the length of the hypotenuse. If 
not, the instrument will display an error signal.

To ensure the accuracy of measurement, take measurements from 
the same starting point of the first order hypotenuse. Then follow 
with the measurement of the right side. Please follow the instructions 
according to the method required. (See diagrams on pg 12-15 to 
determine the appropriate method).
