1 If the process is broken at any point, use new gloves from a new package. 2  Wear sterile gloves only when necessary. 3  Never wash gloves and reuse.  Never use gels and alcohol to clean gloves, use a new pair each time.
The horizontal angle between objects can be measured by: magnetic compass, Brunton Compass, sighting along a protractor, transit, GPS.he horizontal angle between objects can be measured by: magnetic compass, Brunton Compass, sighting along a protractor, transit, GPS.
Divide the sum of your observations by the total number of observations made. For example, if you measured the horizontal angle between two objects daily for 30 days, divide the sum of those 30 observations by 30. Your answer will be the mean horizontal angle.epeat this process for the second object you are making a line of sight with. The difference between their azimuths is the horizontal angle. Repeat this step for each horizontal angle you wish to measure. Add up the relevant horizontal angles.
