accumulated.

Displays the measured air
velocity and temperature.

3. Tapping the list icon allows
optional functions to be
accessed. These include

J. AIR VOLUME MEASUREMENT - TRAVERSING RECTANGULAR DUCTS

Preparing to Traverse a Rectangular Duct

To do a proper airflow measurement (CFM) you should do traverse readings to obtain the
true average airflow through the duct. It is recommended to do at least 12 points of
measurement. There are two ways to perform this test using the SP565, Time Based
Traverse and Spot Based Traverse. Time based is typically easier but both are explained in
the next sections.

1. You will need to determine the easiest access to take your readings. Normally it is best
to enter from the side (Height) of the duct since you will have to drill less holes, but you

may have to drill from the bottom (Width) of the duct. See below.

Not the ideal side to enter the duct
but may be necessary

Choose one
side to enter
the duct.

5. Tap the “Play” icon to
begin the test
process.

1. Prepare the duct as outlined on page 7 and connect the SP565 to the App as outlined
on page 3.

2. Set the App up to measure Air Flow and enter the duct type and size as outlined in sec­tion H.

3. Insert the hotwire probe all the way into the duct at the first hole. Make sure the open
area of the sensor isf acing into the air flow. HINT: If you turn the probe you will see
the readings change up or down, when the reading is at the highest you are in the
proper position.

4. Select “Timed Avg.”.

holes.

11. When the duct has been completely tra­versed and prior to pulling the probe
out of the last test hole, press the
“Stop” icon.

12. The stored reading is the average
Temperature, Velocity, and Volume dur­ing the timed test.

This data can be sent in a CSV file for­mat vial email by tapping the Email

1. Prepare the duct as outlined on page 7 and connect the SP565 to the App as outlined
on page 3.

2. Set the App up to measure Air Flow and enter the duct type and size as outlined in sec­tion H.

3. Divide the duct into at least 12 equal boxes, you will need to take the reading in the
center of each box. Be sure that the sample points are no more than 4 inches apart
from center to center. If needed you can add more sample points (boxes) to cover
larger duct sizes. Insert the hotwire probe all the way into the duct at the first hole.
Make sure the sensor is facing the air flow.

K. AIR VOLUME MEASUREMENT - TRAVERSING ROUND DUCTS

15

Traversing a round duct is very similar to traversing a horizontal duct. The preparation of
the duct is slightly different. When traversing a round duct the traverse must be made
vertically and horizontally.

Preparing the Duct

You will need to drill 2 holes at 90 degrees to each other, similar to the drawing below.
