How to measure using BL-6 Altimeter 

Baseline measure plate  on the targetDistance  is fixed




















Distance is determined first! 
The distance is needed to read measurements on the specific distance scale of 
the instrument (15,20.30,40 m ) 
BL-6 has two release buttons(1) and (2) and indicators. 
Now target the object. 


















release button(1)upper, (2)lower












Low point 'b' 
















The lower point of the object is viewed through the eye piece (7).
The lower button (2) is pressed and this releases the pendulum. 
When the pendulum is stable as shown by the yellow marked pendulum wheel, 
the button (3) is freed ; the indicator is fixed at point "b " 



Upper point 'a' 

















Now view the upper point. by pressing the upper button(1), the pendulum is free to move. 
When stable, the button (1) is released and the indicator arm is fixed at point 'a' 
Both values can be used to calculate actual height,taking the surveyors into account 
(see plate (15) for explanation). 



Control of Measurement accuracy 

The movements of the pendulum can be observed through the viewing tube(7),and 
control of measurement accuracy. 
When the yellow and black marking of the pendulum wheel indicate that the pendulum
has come to rest, the button is released and the indicator fixed. 

Pendulum indicate heights
A:Lower=3 m B:Upper=13 m
Total heghts above the ground=A+B=3+13=16.0 m
