Measurement Considerations
l Do not touch the fan blade with force.
l Do not store or operate the instrument in areas with high
temperature or humidity.
l In use, do not let the strong light directly shine on the fan, in order to
avoid measurement errors.
l Avoid violent vibration。
l Remove the battery before storing the instrument for a long time。
Operation
Air velocity measurement
1. Power the meter by pressing the power button, The
“VEL” icon will appear in the display.
2. If the “VEL” icon disappears in the display, Press the
FUNC button again until the “VEL” icon appear in the
display.
3. Hand-held anemometer let the fan plane of anemometer
be vertically aligned with the wind direction of the airflow.
4. View the measurement on the display
Air duct area setting
1. Power the meter by pressing the power button, Press
the SET button until the “AREA” icon appear in the

display
2. A data bit is flickering, indicating that this value can be
modified.
3. Press the REC button to set the scintillation digit to the
desired value。
4. Press the UNIT button to select the next digit to be
adjusted.
5. After adjusting all the digits, it will jump to the adjusting
unit. The unit will flicker. Press REC button to change
the unit.。
6. After setting up, press the SET button to exit the setting
state and return to the airflow measurement; the set data
will be automatically saved.
Airflow measurement
1. Power the meter by pressing the power button, The
“VEL” icon will appear in the display
2. Press the FUNC button again, the “FLOW” icon will
appear in the display
3. Hand-held anemometer let the fan plane of anemometer
be vertically aligned with the wind direction of the airflow.
4. View the measurement on the display

Note: To measure the airflow, the cross-sectional area of
the tested air duct must be determined and input into the
anemometer.
Data hold
To freeze a displayed reading, press the button. The
“H” icon will appear and the most recent reading will appear
in the display. Press the button to exit the mode and
return to normal operation
MAX/MIN/AVG function
1. Press the button once to put the meter in
MAX/MIN/AVG mode. The meter will now display the highest
reading that occurs while the function is enabled. The “MAX”
icon will appear in the display.
2. Press the button again to display the lowest reading
that occurs while the function is enabled. The “MIN” icon will
appear in the display.
3. Press the button again to display the average reading
that occurs while the function is enabled. The “AVG” icon will
appear in the display.

4. Press again to toggle between the MAX 、 MIN and
AVG readings.
5. To exit the MAX/MIN/AVG mode and return to the normal
real time display, press and hold the button (2
seconds).
Units of measure
Air velocity unit selection
Press the UNIT button to select unit(m/s、km/h、mill/h、ft/m、
ft/s、knots),when measuring air velocity.
Airflow unit selection
Press the UNIT button to select unit(CMS 、CMM 、
CFM),when measuring airflow.
Meter Power and Automatic Power Off
1. Press the button to turn the meter on.
2. Press the button again to turn the meter off.
3. The meter has an automatic power off feature that conserves
battery energy. After 10 minutes the meter automatically
shuts off.
4. To press and hold the button to turn the meter on, the

auto power off function will be cancelled. And the icon
disappears.

Maintenance
Battery Replacement
When the battery voltage is low the ‘ ’ symbol will appear on the
display.
Replace the three (3) 1.5 ‘AAA’ batteries by removing the rear
(center) battery compartment screw and accessing the battery
compartment. Observe polarity when placing the batteries in the
compartment. Ensure that the compartment cover is securely fastened
when finished.
Cleaning and storage
Caution
To avoid damaging the instrument housing, do not use
corrosive or solvent to clean the instrument.
Periodically wipe the case with a damp cloth and mild detergent; do
not use abrasives or solvents.
Store the meter in an area with moderate temperature and humidity
(refer to the operating and storage range in the specifications chart earlier
in this manual).
