Indirect Measurements

Indirect measurements are used when direct measurement is not possible. In- direct measurements are calculated from measurements of the hypotenuse and one side of a right triangle (triangle with a 90-degree angle). For instance, if calculating the height of a wall from the ground, measurements would be taken to the top of the wall (hypotenuse), and perpendicular to the line between the two measurement points at the wall base (side). From these two measurements, the distance between the two measurement units is CA ventilated

Indirect measurements are less accurate than direct measurements. For greatest accuracy with Indirect Measurements, hold the micro LM-400 in the same position (only changing angle) for all measurements. Make sure that the laser beam is perpendicular to the line between the measurement points when measuring the side of the triangle. All measurements need to be to points on a single straight line.
