Displayed readings freeze. Indicates Record mode is active. Indicates the displayed reading is the Maximum, Minimum, or Average measurement.
Keypad Overview Use to navigate up in setup mode menus. Use to freeze the current reading on the LCD when performing a measurement. Use to confirm entry when in setup mode menus. Use to switch between air velocity and air flow when taking mea- surements.
Probe Overview Hot Wire Probe (Part number A581) 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.
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 keys operate.
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.
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.
Definition of Free Area Free Area is the total area in which air flows through a supply out- let 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.
Taking a Measurement 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.
Selecting Between Air Velocity and Volume (Air Flow) 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 read- ing to be accurate.
Recalling a Stored Reading 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 stored reading. 3.
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 rec- ommended 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 Traverse of a Horizontal Duct 1. Insert the hotwire probe into the DC580 and turn the meter on. 2. Enter the duct type and size and prepare the duct for transverse measurements as outlined on page 13. 3. Press the key.

Time Based Traverse of a Horizontal Duct (Continued) 9. Pull the probe out and insert it into the next test hole all the way into the duct. 10. Press the key to begin recording. Repeat these steps for all test holes. 11.
Point Based Traverse of a Horizontal Duct 1. Insert the hotwire probe into the DC580 and turn the meter on. 2. Enter the duct size and prepare the duct for transverse measure- ments as outlined on the previous page. 3. Press the key.

Point Based Traverse of a Horizontal Duct (Continued) 9. Press the key to record the reading. Repeat these steps for all test holes. 10. When the duct has been completely traversed press the key to store the readings. See section page 11 on storing read- ings.
Preparing to Traverse a Round Duct 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 draw- ing below.
Time Based Traverse of a Round Duct Using Time Based Traverse Record Function 1. Insert the hotwire probe into the DC580 and turn the meter on. 2. Enter the duct type and size. Prepare the duct for transverse measurements as outlined on the previous page. 3.

When the duct has been completely traversed press the key to store the readings. See page 11 on storing readings. This will store the average air velocity, air volume, and temperature readings.
3. Traversing a Grille Using Time Based Traverse Record Function 1. Insert the vane probe into the DC580 and turn the meter on. 2. Enter the duct type and size. Remove the grille if possible or use the free area specification from the manufacturer. 3.

Activate / Deactivate Auto Power Off The DC580 always defaults to auto power off mode. When auto power off is activated the annunciator will show in the upper left corner of the display. To deactivate auto power off from normal operation mode press and hold the key until the annunciator turns off.
Activate / Deactivate Bluetooth Bluetooth can be activated in order to communicate with the DC580 app. 1. Activate Bluetooth by pressing and holding the key until the annunciator shows in the lower right corner of the display. The annunciator will blink until connected to a phone. 2.
