In addition to the graded vertical rulers, there are two graded rulers at the top of the ER stand to measure
rotation of the upper and lower arms. Each ruler provides measures in increments of 5 degrees, up to
110 degrees to the left and 110 degrees to the right.
You now have the basic information necessary in
preparation for performing functional tests and even
designing your own protocols. The following section will demonstrate how to connect the ER to the
Computer Diagnostic System, to achieve automatic data acquisition and analysis as well as automatic
report generation. Please ensure that you thoroughly read and understand the following section prior to
attempting to use the Computer Diagnostic Component. Many areas of difficulty in data acquisition arise
from incorrect connections between the software and hardware components of the ER.
The upper ruler indicates the angle of rotation of the lower
arm.
The lower ruler indicates the angle of rotation of the upper
arm.
