The SERIES SAH SMART Air Hood™ Balancing Instrument is the most accurate and
easy to operate air ow hood on the market. By using the included hood stand and
wireless communications to the handheld, a single operator can balance a branch in
less time than traditional balancing teams. Besides being lighter than most traditional
capture hoods, the ergonomic design makes the Series SAH easy to maneuver, with
less physical stress. The rugged polypropylene base hood features patented Quad
Flow Design Technology for controlling air ow and minimizing back pressure, which
yields superior measurement accuracy. The Wi-Fi direct communication gives reliable
communication with a distance of up to 200 yards between the hood and the handheld
test instrument. The SMART Air Hood
Application Software which reduces the number of steps in the air ow balancing
process using Predictive Balancing’s Express Balance mode. Predictive Balancing
is a method of predicting the optimal ow set point for each register and the order in
which they should be adjusted.
Please see Bulletin TE-SAH for general installation instructions.

BALANCING PROCEDURE
The START button will start the balancing process. The START button will only be
enabled if there are two or more registers in the register list.
The rst step of the balancing procedure is to take an initial sweep of all registers
within the selected branch with all dampers open.
Press the register button again to store the reading, at which point it will change from
white to green, indicating that a value has been stored for that register.
Repeat this procedure until all of the registers have been measured. Pressing on a
register again allows for a retaking of that register if needed.
Red indicates that a reading still needs to be taken from the register. After selecting
the register to measure, its button will turn from red to white, indicating that it is the
active register.
If the slide out menu is opened, the following choices will be shown.
“Screen Timed Out Settings” allows the hibernate mode to be turned on. If the option
is turned on, then the current screen will hibernate after timing out based on the
handheld instrument’s hibernate time in the Settings->Display->Sleep setting. If the
option is turned off, then the device will stay awake and not go into hibernation. This is
also available on the Initial Reading, Balancing, and Final Reading screens.
16
To enter data for a register that cannot be measured by the hood use the “Manually
Enter Data” in the slide out menu. A register needs to be selected to enter data
manually.
Pressing on the EXPRESS button starts the Express balancing method, which starts
with the Place the Smart Hood dialog box. As shown in the below example, the app
will direct you to the register to measure:
If a register is selected and “Manually Enter Data” is pressed, then a dialog will appear
that allows for a value to be entered for the register.
Touch to close the
dialog and set the
register’s value
Once all of the registers have been measured, the NEXT button at the bottom will
become enabled. Press and hold that button until the balance method selection screen
appears.
Select a balancing method.
Press and hold the OK button to bring up the dialog box asking to conrm that the
hood is correctly placed.
Touch to close
the dialog without
storing the reading
If the YES button on the hood placement conrmation dialog was pressed then the app
will bring up the Adjust to Target screen.
Touch to close the
dialog and take a
pre-adjust reading
17
“Manual Data” will bring up the Manual Data screen similar to the initial sweep manual
entry dialog. After the manual data is entered, another dialog will appear. This manual
entry dialog asks for the air ow of the register after adjusting (if it can be adjusted).
The dialog includes the target air ow that the register needs to reach to balance the
system.
Touch to enter
as the adjusted
value for that
register
If the CANCEL button is pressed, then a Pause Balancing screen will be brought up.
Pressing the PAUSE button in the pause dialog will store the current location and data
within the selected balancing method and return back to the Branches screen.
While in this screen, the damper needs to be adjusted to match the target. Press and
hold the NEXT button to bring up the next screen which will guide you to the next
register to measure and adjust. Once all registers except the key register are adjusted
the app will require a post reading from all the registers. The app will guide you through
the post reading process.
The options and controls of the Final Reading screen are the same as in the Initial
Readings screen. This screen is to gather readings to calculate the error ratio of the
balancing process which is displayed on the next screen.
Once all of the registers are measured, press and hold the NEXT button, to bring up
the Final Results screen. This screen displays how accurate the balancing method
was.
