Optional DU159 Verication

Plate shown.

□ Tape the optional ow

Verication 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 DM32 to measure

“Flow: CFM” @25 Pa.

□ Tap [Set Speed], then

adjust with Jog keys until

[Channel A] reads close to

25 Pa.

□ Read the Verication

Plate to determine the

acceptable range for ow.

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.

□ Set [Time Average] to 5 seconds in [Settings].

□ Tap [Channel B] and select“Pressure: Pa”.

□ 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 Channel A and Channel B 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.

Check the DucTester system monthly with a

range then system needs full calibration.
