Probe
Step 3: Select proper Range Selector (D).
Note: For velocities below 2500 feet per minute, use the Range Selector
with black letters; for velocities above 2500 feet per minute, use the
Range Selector with red letters.
Step 4: Connect Range Selector (D) to loose ends of hoses (C) that are
already connected to the meter (A) as follows:
