Air Velocity Measurements
1. Connect the sensor to the sensor input jack on top of the meter.
2. Turn on the meter using the Power button.
3. Select the VELOCITY function using the FLOW / VELOCITY button. The LCD will display VEL
when the velocity mode is selected.
4. Select the desired temperature units using the C/F select button. The LCD will reflect the current
unit selection.
5. Select the desired air velocity units
using the UNIT button. The LCD will
reflect the current unit selection.
6. Place the sensor in the air current to
be measured with the
symbol on the inlet side of the vane
(see diagram).
Air Direction
7. View the air velocity and
temperature readings on the LCD
Display. The large main LCD
display shows the Air Velocity
reading. The lower LCD sub-display
shows the temperature reading.
Data Hold
While taking measurements, press the HOLD button to freeze the LCD reading.
The HOLD indicator will appear on the LCD when the display is in Data Hold mode.
Press HOLD again to return to normal operation.
Maximum and Minimum Recording
The 407113 allows the user to record and view the highest (MAX) and lowest (MIN) readings.
1. Press the RECORD/RECALL button once. The REC indicator will appear on the display and
the meter will begin recording the MAX and MIN values.
2. Press the RECORD/RECALL button to stop the MAX/MIN recording and display the maximum
reading. The MAX indicator along with the maximum reading will appear on the LCD display
3. Press RECORD/RECALL again to view the minimum value. The MIN indicator along with the
minimum reading will appear on the LCD display.
4. To return to normal operation, press and hold the RECORD/RECALL button for approx. 3
seconds. The display indicators REC, MAX, and MIN will disappear.
NOTE: Placing the meter in the RECORD/RECALL mode by pressing
the RECORD/RECALL button disables the AUTO POWER OFF feature.
NOTE: Handle the vane carefully. If the metal vane blades are inadvertently
bent or damaged erroneous readings may result.

Air Flow (Volume) Measurements (CMM / CFM)
1. Connect the sensor to the sensor input jack on top of the meter.
2. Turn on the meter using the POWER button.
3. Select the FLOW mode using the FLOW/VELOCITY button. The LCD will display FLOW CFM or
FLOW CMM when the flow function has been selected.
4. Select the desired air flow units: CMM (cubic meters per minute) or CFM (cubic feet per minute)
using the UNIT button. The LCD will reflect the selection.
5. Measure the dimensions of the duct or vent and calculate the area in square feet or square
Note: If the dimensional measurements are made in inches (or cm), convert them feet (or meters)
before calculating the square area.
button to increment
6. Press the AREA button to begin entering the area in m or ft . Use the
the flashing digit, use the
button to decrement, use the button to select the next digit, and
use the button to set the decimal point.
7. Press the ENTER/RESET button after the area value has been entered. The bottom display will
indicate the area entered in ft or m . The main LCD displays the Air Flow in CFM (cubic feet per
minute) or CMM (cubic meters per minute). If the CFM or CMM reading exceeds 9999, use the
displayed X10 or X100 multiplier to calculate the reading.
8. Note that for FLOW measurements, three modes apply: The normal, default mode, where the
actual flow is indicated and the two modes described below under 2/3 MAX Flow and AVG
Note: The temperature function is not active in the FLOW mode.
2/3V MAX Flow Mode
In this mode the meter will display two-thirds the measured Flow (Volume). To access this mode,
ensure that the meter is in the FLOW mode (via the FLOW/VELOCITY button) and then press the
FLOW MODE button until the 2/3V MAX display icon appears. Now the Flow display will be 2/3 the
actual measurement. To return to the normal display mode, press the FLOW MODE button until the
2/3VMAX and the AVG icons switch off.
AVG (Average) Flow Mode
In this mode the meter will display the AVERAGE Flow for up to 20 readings. To access this mode,
ensure that the meter is in the FLOW mode (via the FLOW/VELOCITY button) and press the FLOW
MODE button until the AVG display icon appears. Now each time the AVG/START button is pressed
a reading will be taken and averaged. The lower LCD display becomes a 20-reading counter and
with each reading taken the counter is incremented. Allow 3 or 4 seconds between AVG/START
button presses for the display counter to update. The main LCD displays the averaged Air Flow
value. To return to the normal display mode, press the FLOW MODE button until the AVG icon
switches off.
RS-232 PC Interface
The 407113 is equipped with a 3.5mm phone jack (meter top) for connection to a PC for data
acquisition purposes. For streaming of data to a PC via the RS232 Output jack, the optional
407001-USB kit (RS232 to USB cable and driver CD) along with the 407001 software (available free
at are required. Instructions for use are provided with the data acquisition
software/hardware kits.

Battery Replacement
When the LBT icon appears on the LCD, the 9V battery must be replaced.
1. Remove the rubber holster that surrounds the entire meter
2. Slide off the rear battery compartment
3. Replace the 9V battery
4. Affix the battery compartment cover and the meter holster
Useful Equations and Conversions
Area equation for rectangular or square ducts
Height (H)
Area (A) = Width (W) x Height (H)
Width (W)
Area equation for circular ducts
Area (A) = pi x r2
Where pi = 3.14 and r2 = radius x radius
Cubic equations
CFM (ft3/min) = Air Velocity (ft/min) x Area (ft2)
CMM (m3/min) = Air Velocity (m/sec) x Area (m2) x 60
NOTE: Measurements made in inches
must be converted to feet or meters before using the above formulae.
