First Connection
Step One: On your smartphone, go to Apple App Store or Google Play and
download the AAB Smart ABM-200 app marked with a blue icon .
When installing the app, your smart device will ask for you to approve certain
permissions such as access to your contacts. This is necessary in order to email
reports directly from the app. It will ask for access to your location, this is for
geotagging your location. It will ask for access to your photos, this gives you the ability
to add your company logo to reports. None of the items granted for access is used for
any purpose other than your use of the meter. AAB does not gain access to, receive
or retrieve any of your personal data or information.
Step Two: In preparing your new ABM-200 for use, remove the white plastic
tab/battery insulator. To do so, simply pull the white and green tab in the direction of
the arrow.

Step Three: Connecting the ABM-200 to the app.
Start the app by selecting ABM-200 blue icon in the app list. This will bring you to
the start screen.
On the ABM-200, press the power button marked with the AAB logo. The app screen
will change to show the device is connected and ready to take readings.
The ABM-200 is now paired with the smartphone and ready for use.
Turning the app off: For android, press the phone’s back button twice. For Apple,
Turning the ABM-200 off: Hold the power button 3 seconds. The ABM-200 will also
shut off automatically after 30 seconds, when not connected to the app.

Settings
Company Name: Used to display your company name on reports
Measurement units: Allows the selection of Metric or Standard units depending on
the regional and user needs.
Send History To: This field can be used to relay the history log to an email address of
your choosing.
Manual Free Space Adjust (AK Factor): This setting is used to offset the amount of
free area left by a grille or similar obstruction to the duct. Consult the manufacturer of
the grille for the amount of area obstructed or open.
LED Indicators
The AAB logo is illuminated by an LED for confirmation that the unit is operational.
The LED will flash when the button is pressed until connection. Once connected, the
LED will stop flashing. The phone will inform the user of the connection to the ABM-
200.
When shutting off the ABM-200 with the power button, the LED will fast flash for 1
second to indicate shutdown.
General Use
The ABM-200 was designed for taking air speed, temperature, and humidity in order
to aid the contractor in effectively balancing commercial and residential HVAC
systems.

Sending and Editing Reports
Reports can be accessed and sent with or without the phone connected to an ABM-
200. To access saved reports, press the three bar menu button in the upper left
hand corner of the app. In the dropdown menu, choose History. All of the reports

Maintenance
Changing the battery
Step one: Pull lip of blue sleeve out of fan groove. This may require the use of a small
flathead screwdriver.
Step two: Remove sleeve by pulling it over the top of the ABM-200 and off of the
bottom.
Step three: On the back side of the ABM-200, remove the battery door by pulling it
downward.
Step four: Replace battery with a CR2450 coin cell. The positive (+) faces away from
the circuit board.
Step Five: Assemble using steps one through three in reverse. When placing the
sleeve on the ABM-200, align AAB logo with white button (as shown in picture X).

Cleaning
To clean the ABM-200, start by removing the blue sleeve (see Changing the Battery).
Use a damp rag with mild detergent and wipe down exterior. Do not clean with the
sleeve on the ABM-200, as water could enter the sensor port, causing damage and
voiding the warranty.
Storage
The ABM-200 is to be stored out of direct sunlight in temperatures between 32° and
95° F (0° and 35° C).

Technical Data
Operational temperature range: -40°F to +185°F (-40°C to +85°C)
Operational temperature range, full accuracy: -32°F to +149°F (0°C to +65°C)
Power: Panasonic 3.6V, CR 2450 Coin Cell Lithium Battery
Battery Life: >500 hours
Auto power: Shuts off 30 seconds after closing or minimizing app or no connection
Units of Measure: inWC, inHg, psi, mmWC, mmHg, Pa, kPa, mBar, fpm, cfm, l/s,
m/s, F, C, RH%, lb/ft3
Range & Accuracy
Airflow Velocity: 44 –12,320 fpm ± 0.5%
Temperature: -40 to 185°F ± 0.5°F
Humidity: 0-95% ± 3%
Pressure: 300-1100 mbar ± 0.12 mbar
*Please note that we are often asked the maximum volume of airflow, this is totally
dependent on the size of the duct. For example: 12,320 fpm through a 20” x 24” grille is
41,028 CFM. So the range of this meter goes high enough to satisfy any practical HVAC
application.

Airflow Velocity: speed in which the air is being moved into or out of the duct.
Airflow Volume: amount of air being moved into or out of a duct in a given amount of
time.
Humidity: a quantity representing the amount of water vapor present in the air.
AK-factor (K-factor): amount of space blocked by a grill or other duct cover. Typically
supplied by the manufacturer.
Relative Humidity: the amount of water vapor present in air expressed as a
percentage of the amount needed for saturation at the same temperature.
Temperature: the degree of measured heat in an environment.
Temperature Differential: difference in temperature between two spaces in a
building, or between indoor and outdoor temperature.
Wet Bulb: Temperature acquired by use of a thermometer with the bulb enclosed in
