Probe Overview

Hot wire probe for the DC580. This probe can be used to measure
air velocity and flow inside ducts. The white dot should face into
the air stream. The probe can be expanded by pulling out the sen­sor shaft enabling the probe to extend like an antenna.

Temperature
Sensor

Air velocity sensor
underneath protective
hood.

Slide the sensor protective
hood all the way down to
perform air velocity mea­surements. Make sure the
temperature sensor is not
covered.

Replace the cover when
not in use.

Hot Wire Probe Sensors

Hot Wire Probe (Part number A581)

Vane Probe (Part number A582)

Vane probe for the DC580. This probe can be used to measure air
velocity and flow at registers, hoods, and other openings. The
white line/dot should face into the air stream.

Note: The DC580 can be purchased to include one or both of
these probes. These probes are also available for purchase sepa­rately. Please see page 36 for information on kits and probes.

Turning the DC580 on and Connecting a Probe

6

To turn the DC580 on press and hold the key for more than two
seconds.

If a probe is not connected the display will read ‘oPEn’. When this
is displayed only the and keys operate.

When a probe is connected the DC580 will auto detect which probe
has been connected and will act accordingly.

Hot wire probe - Make sure the hotwire probe cover has been put
into the closed position before connecting the probe. When the hot
wire probe is connected a 5 second warm up period will begin and
the display will read ‘H---d’ and display the countdown. After the
countdown the DC580 is ready to take measurements. Slide the
cover down to the open position and perform tests.

Vane Probe -

Connect the vane probe and the DC580 is ready to

take measurements.

After power is turned on and a probe is connected the DC580 is
ready to take measurements. Use the setup modes as needed to
adjust units of measure and duct size.

Duct Type and Size Setup Mode

8

When measuring air velocity, the volume of air or airflow can be dis­played. This is a calculation based on the duct type and size. For air
flow to be accurate the duct size needs to be entered into the
DC580.

The units of measure used in the duct size can be set by following
the steps outlined in section page 7.

1. Connect a probe to the DC580 and turn it on as outlined earlier.

2. Press the key to activate duct size entry mode.

3.Use the key to cycle through the duct type. The types are
round, rectangular, and free area. Select free area if measuring at a
supply or return with an obstruction like a grille. NOTE: The free area
of the duct must be known. This is published by the grille manufac­turer.

4. Once the duct type is displayed, =round, =rectangular, or free
area press the key to confirm the selection.

Round Duct - Use the keys to enter the diameter

of the duct. Press the key to confirm the selection.

Rectangular Duct - Use the keys to enter the

height (H) of the duct. Press the key to confirm the selection.

Use the same keys to enter the width (W) of the duct. Press the
key to confirm the selection.

Free Area - Use the keys to enter the free area of
the duct. Press the key to confirm the selection.

For more information on free area please see the next page.

www.GlobalTestSupply.com

Definition of Free Area

Free Area is the total area in which air flows through a supply out­let or a return grille. Free area is the effective area of the outlet or
grille and takes into account any restrictions.

If a grille is not used and there is no restriction on the area in
which air flows then the free area is equal to the actual area. This
is the case when measuring air flow at the middle of a duct, or if
the grille is removed from the return or supply duct.

When measuring airflow with a grille in place or restriction present,
the free area is the total area minus the area covered by the
restriction (grille fins).

Grille manufacturers publish free area specifications and this is the
most accurate information to use when setting up your DC580 to
measure air flow (volume).

Whenever possible it is best to use free area when entering duct
size. This will ensure the most accurate air flow reading.

Taking a Measurement

10

1. Insert the hot wire or vane air velocity probe into the DC580. If
the hotwire probe is used make sure the sliding cover is over the
air sensor. (See page 5)

2. Press and hold the key until the DC580 turns on.

3. If the hotwire probe is used the DC580 will countdown from 5.
During this time the hotwire sensor is being warmed up. If the
vane probe is used there will be no countdown.

4, If necessary, set the units of measure and duct size as outlined
on page 7 and 8.

5. Insert the air velocity probe into the air stream with the white dot
facing into the air. If the hotwire probe is being used make sure the
sliding cover is in the down position and the sensor is exposed.

6. The air velocity will be displayed in the upper display and the
temperature will be displayed in the lower display.

The most accurate way to take a reading of a duct or grille is to
traverse it and take the average reading. The DC580 can do this
without the need of manual calculations.

The following pages include instructions for traversing ducts and
grilles along with various features and functions available on the
DC580.

When an air velocity is displayed on the DC580 the key can be
pressed to toggle the top display between air velocity and air flow.

Note: The duct size must be entered correctly for the air flow read­ing to be accurate. Air flow is a calculation based on the duct size
and the measured air velocity.

Storing a Reading

The displayed reading can be stored in memory. This will store the
air velocity, air volume, and temperature.

1. When taking a measurement, once the
reading is on the display press the key.

2. The display will prompt you for a memory
location to store the reading. To cancel
press the key or use the keys to select the
memory location to store the reading then press the key.

Clearing Memory: Saving data to the same memory location will
write over the data already saved. All locations can be cleared by
pressing the key to enter memory mode then pressing and
holding the key for approximately 3 seconds.

Stored readings can be recalled and displayed on the DC580.

1. With the DC580 in normal operation press the key.

2. The display will prompt
you to select a memory
location to display the

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 DC580, 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 read

­ings. 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

side to enter
the duct.

Preparing to Traverse a Round Duct

20

Preparing the Duct

To do a proper airflow measurement (CFM) you should do traverse
readings to obtain the true average airflow through the duct. You will
need to drill 2 holes at 90 degrees to each other, similar to the draw­ing below.

1. Take your measurements by inserting the hotwire probe into the
drilled hole. and use the insertion depth chart to determine how far in
the duct you will go for each point. Then you will repeat for the other
hole.

2. Be sure you have the tip of the hotwire pointed into the flow of air,
there is a white dot on the tip, this should be inline with the 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.
