Introduction

Thank you for purchasing TPI brand products. The TPI DC580 digital air

velocity meter is a state of the art, easy to use air velocity tester designed to

display air velocity, air flow, and temperature. It can be used with the TPI

DC580 app to generate reports and store readings.

The DC580 can be ordered in several configurations:

Part Number Description

DC580C1 DC580 w/ Hotwire probe & Carry case

DC580C2 DC580 w/ Vane probe & Carry case

DC580C3 DC580 w/ Hotwire & Vane probes & Carry case

This manual covers all features for the DC580 and the use of both

hotwire and vane type probes.

Features & Guidelines

Features:

• Measure air velocity and temperature simultaneously

• Field replaceable smart hot wire and vane probes

• Communicate with Android Smart Phone via Bluetooth LE and TPI App

• Display minimum, maximum & average

• Multiple measuring units: m/s, km/h, ft/min, knots, mile/h

Guidelines:

Always allow the DC580 sufficient time to acclimate to the test environ-

ment especially when moving from location to location.

Always operate the DC580 and probes within the temperature and

humidity limits outlined in the specifications area of this manual.

Never allow any object to enter the sensor area of the hotwire probe or

vane probe.

Never attach the DC580 magnetic boot to a hot surface.

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 sen-

sor 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 mea-

surements. 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 sepa-

rately. Please see page 36 for information on kits and probes.

Turning the DC580 on and Connecting a Probe

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.

Units of Measure Setup Mode

Setup the units of measure to be used. The meter will default to

these settings upon start up. These can be changed as necessary.

1. Connect a probe to the DC580. Turn the DC580 on by pressing

and holding the key for more than 2 seconds.

2. Press the key to enter the units of measure setup mode. The

air velocity annunciator will begin flashing.

3.Use the key to cycle through the air velocity units until the

required unit is shown. Press the key to move to the air flow

units.

4. Use the key to cycle through air flow units. CFM and CMM are

available. When the desired unit is displayed press the key to

move to temperature units.

5. Press the key to cycle between temperature units. ºF and ºC

are available. When the desired unit is displayed press the key

to move to duct dimension units.

6. Press the key to cycle through the duct dimension units.

Inches (in), centimeters (cm), meters (m), and feet (ft) are available.

When the desired unit of measure is displayed press the key.

7. The DC580 exits the units setup menu and returns to normal oper-

ation.

Note: At any time in the above procedure the key can be

pressed to return to normal operation. Units of measure that were

not adjusted will remain unchanged.

Duct Type and Size Setup Mode

When measuring air velocity, the volume of air or airflow can be dis-

played. 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 manufac-

turer.

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.
