Pitot Probe
Step 1: Remove sensing port caps.
Step 2: Connect two hoses (C) to sensing ports (B).
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 the hoses to the Range Selector (D) as follows: The
plus (+) sensing port of the meter to the plus (+) sensing port of the
Range Selector and the minus (–) sensing port of the meter to the minus
(–) sensing port of the Range Selector.
Step 5: Insert the Pitot Probe (E) into the Range Selector (D). Push the
Pitot Probe firmly down until the collar of the probe rests against the top
of the Range Selector.
Step 6: Check position of switch button (Da) on Range Selector (D). It
must be released and left in the out position.
Step 7: Check position of switch plate (Db) on Range Selector (D). It
must be positioned for the proper velocity range.
Step 8: Proceed to make necessary duct velocity measurements. See
page 13 for proper procedures.
Low Flow Probe
Step 1: Remove sensing port caps.
Step 2: Connect the Low Flow Probe (F)
directly to the meter (A) by placing it onto
the sensing ports (B); no hoses are
required. It fits only one way onto the
meter, with the arrow pointing to the left
when viewing the meter from the front.
