PREPARATION FOR USE

Diffuser 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 Range Selector (D) to loose ends of hoses (C) that are
already connected to the meter (A) as follows:
For Supply Measurements
Connect 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.
For Return and Exhaust Measurements
Connect the plus (+) sensing port of the meter to the minus (–)
sensing port of the Range Selector, and the minus (–) sensing port
of the meter to the plus (+) sensing port of the Range Selector.
Step 5: Insert Diffuser Probe (E) into the Range Selector (D). Push the
Diffuser 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 pushed in and turned to latch it in.
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 velocity measurements; see page
11 for procedures.
