3  READING

 

METHOD 

Tilt data can be read by a field pc and will display in engineering units (sine 

θ

).  The reading will take 

approximately 3 seconds to stabilize.   

Data should be taken on standard horizontal installations for all 4 axes as follows: 

Position the Tiltmeter on the Tiltmeter Monument so that two diagonally opposite studs (ie, stud 1 & 
stud 3) are in contact with the long alignment bar, and one of the alternate studs (ie, stud 2) is in 
contact with the short alignment bar (See Figure 4).  Each position is named for the visible unused 
stud (ie, stud 4).  Repeat for all 4 positions. 

For a Vertical Tiltmeter Monument, only 2 positions can be read on each end of the Tiltmeter, always 
with the Tiltmeter approximately vertical.
