Connecting the Velocity Matrix to the Micromanometer
The positive port (+) is located on the side of the Velocity Matrix that is opposite the handle assembly.
The positive port (+) on the Velocity Matrix will be connected to the (+) port on the micromanometer, and
the negative port (
–) on the Velocity Matrix is connected to the (–) port on the micromanometer.
Standoffs can be screwed together to make different lengths and are used to maintain a fixed and level
orientation away from a filter. The standoffs are attached to the positive (+) side of the velocity matrix.
The handle assembly is attached to the downstream or negative (
–) side in the center of the velocity
matrix (see Figure 11).
