Sets of Positions Needed
For the three-measurement, three-input correlation, any set of three orthogonal
positions can be used. A typical rotation series is as follows.
For the Model 5400 Series with the door on the right side (looking from the apex),
position the manipulator with the 0-degree mark pointing toward the right side of
the door. Secure the EUT to the top turntable.
See Manual EUT Manipulator Positions for Three-Position Emissions Test –
Model 5400 Series on page 64 for these steps:
 a—Shows a schematic of this arrangement as seen looking in the door. This
is the first test position used to measure V
xyz
.
 b—Release the cradle tilt lock pin and swing the cradle away from the door
to the 90-degree tilt position. The EUT x-axis now points down, as shown.
 c—Rotate the top turntable to 90-degrees (as shown), and measure V
yzx
.
 d—Rotate the top turntable to the 180-degree position.
 e—Rotate the bottom turntable to 90-degrees and measure V
zxy
.
