Optional DU159 Verification

Plate shown.

□

Tape the optional flow

Verification Plate to the

Flange and attach the

red tube.

□

Attach the Flex Duct to the

exhaust side of the fan

to pressurize the Flex Duct.

□

Stretch the Flex Duct to

it’s full length.

□

Set the DM-2 to measure

“Flow” in “CFM @25 Pa”.

□

Adjust the speed until

“PrA” reads close to 25 Pa.

□

Read the Verification

Plate to determine the

acceptable range for flow.

Typically, 100 to 110 CFM

is a pass.

Check gauge operation and check for blocked, leaking or

pinched tubes weekly, and anytime results are in question.

To perform the gauge check, you will need the gauge

and Umbilical.

□

Press

[Exit]

[Time Average]

until “4s” appears.

□

Press

[Mode]

repeatedly

to display “PrB”.

□

Connect the yellow tube between the red and

yellow ports.

□

Repeat between different ports with each of the

tubes you use for testing.

Field check gauge weekly

If readings on “PrA” and “PrB” are within 2% and

don’t drop rapidly, the tube is not blocked or

leaking and the gauge is correct.

Checking your gauge

and tubes regularly will

eliminate a common

source of error in

readings.

& Low-Range
Ring

(Low) Part #: DU155

Check the DucTester system monthly with a

known setup―if flow is outside the acceptable

range then system needs full calibration.
