Indirect height measurement (Pythagoras)
Using this method the length of an unknown straight-line
segment can be determined via the Pythagorean Theorem. This
method is suitable for e.g. height measurements.
The measurement result is calculated by determining the
distance A and the inclination angle (standard setting) or by
determining the distances A and B.
A
Measurement with distance A and inclination angle:
1. Briefly press the Button for indirect measurements (9) one
time.
ð The symbol
for indirect measurements appears on
the display.
ð The inclination angle is displayed in the third line of the
upper measurement value display on the right-hand
side (see example 33.0°).
ð The bar with number 1 (hypotenuse) flashes.

2. Aim the device at the highest point (A) and briefly press the
Switch-on/measurement button (7) once to perform a
measurement. Make sure to hold the device as steady as
possible and place it level on the ground with the two rear
edges. The position at the two rear edges must not be
changed during the measurements!
ð Both measurement and calculation are effected.
ð The horizontal (1st line) and vertical (2nd line) distance
values are indicated in the upper measurement value
display.
ð The line segment to be determined is displayed as
result in the lower measurement value display (25).
Measurement with distances A and B:
1. Briefly press the Button for indirect measurements (9) one
time.
ð The symbol
for indirect measurements appears on
the display.
ð The bar with number 1 (hypotenuse) flashes.
2. Press the Inclination button (15) for a long time.
ð There will be no angle displayed.

4. Align the device horizontally (point B) and briefly press the
Switch-on/measurement button (7) one time to measure
the horizontal distance.
ð The second measured value will be indicated in the
second line of the upper measurement value display.
ð The line segment to be determined is displayed as
result in the lower measurement value display (25).
