Static Pressure Probe

Step 1: Remove sensing port caps.
Step 2: Connect two hoses (C) to sensing ports (D).
Step 3: Select proper Range Selector (D).

ters; for 1–10" static pressures, use Range Selector with red letters.
Step 4: Connect the hoses to the Range Selector (D) as follows:
For Positive Pressure Measurements
Range
Selector
Connect the plus (+) sensing port of the meter to the plus (+) sensing
port of the Range Selector. Connect the minus (–) sensing port of
the meter to the minus (–) sensing port of the Range Selector.

For Negative Pressure Measurements
Connect the plus (+) sensing port of the meter to the (–) sensing port
Switch
Plate
of the Range Selector. Connect the minus (–) sensing port of the meter
to the plus (+) sensing port of the Range Selector.
Step 5: Select the proper Static Pressure Probe (E)
Note: For 0–1" static pressures, use the Static Pressure Probe with
black letters. For 1–10" static pressures, use the Static Pressure
Hoses
Probe with red letters.
Step 6: Insert the Static Pressure Probe (E) into the Range Selector (D).
Push the probe firmly down until the collar of the probe rests against the
Sensing
top of the Range Selector.
Ports
Step 7: Check position of switch plate (Da) on the Range Selector (D).
It must be pushed in and turned to lock it in position.
Step 8: Check position of switch plate (Db) on the Range Selector (D).
It must be to the extreme left.
Step 9: Proceed to make duct static pressure measurements. See page 13
for proper procedure.
