4. Operating guidance
4.1 Power On/Off
Press the “ ” key to turn on or off the anemometer
power.
4.2 Reading hold
In the measurement process, if the reading should be
kept, press "HOLD" key to lock the reading, and display the
HOLD symbol; press it again to unlock.
Note:
In the reading hold state, “FUN”, “MAX/MIN” and
“UNIT” keys are invalid.
4.3 Backlight
In the measurement process, if the ambient light is too dark
to read, you can press " " key to open the backlight.
Backlight timer is set to 15 seconds. During this period, you can
press " " key again to turn off backlight at any time.
Note:
The luminous body of backlight is LED with large
operating current. Frequently using backlight will
shorten battery life. Do not use backlight when
unnecessary.
When the battery voltage ≤ 7V, the " " (low battery)
symbol will show on the display. However, in the case
12
Digital Anemometer
Operation Manual
Operating guidance
of using the backlight, if the battery voltage ≥ 7V, the battery
voltage drops because of its larger operating current, "
"
symbol may show (when "
" symbol is showing, the
accuracy of the measurement can’t be guaranteed). At this
moment, you needn’t replace battery until the "
" symbol
display again under normal use condition without using
backlight.
4.4 Wind speed measurement
Place the detector (fan) into the test environment,
"VEL" symbol will display on the screen, measurement is
done with the fan surface perpendicularly to the wind
direction.
Note:
1. If the detector (fan) is not aiming at the wind direction,
which will bring the measurement error.
2. For steady wind, the detector (fan) will get maximum
reading when it is aiming at the wind direction.
4.5 Wind speed measurement
When using the meter to measure air volume, you can
press “UNIT” key to select the measurement unit you
required (m/s, km/h, mill/h, ft/m, ft/s, knots).
4.6 Area setting
To measure air volume, you should first determine the
area of air flue to be, area input steps are shown as
following:
13
Digital Anemometer
Operation Manual
Operating guidance
①．Press “FUN” key to make “AREA” display on the
screen.
②．Use the “MAX/MIN” and “UNIT” keys to adjust value
and unit, after adjusting area unit (m², ft²), then press
“MAX/MIN” key. There should be an audible buzz,
indicating that area input is completed and settings are
saved.
③．To change the area setting, please repeat the step ②.
4.7 Air volume measurement
Place the detector (fan) into the test environment. Use
the “FUN” key to set the meter to the Air volume
measurement mode; the "FLOW" symbol should display on
the screen.
Measurement is done with the fan surface perpendicular
to the wind direction.
Note:
1. If the detector (fan) is not aligned in the wind direction,
the measurement can be skewed.
2. For steady wind, the detector (fan) will get maximum
reading when it is aiming at the wind direction.
4.8 Air volume unit selection
When using the meter to measure air volume, you can
press the “UNIT” key to select the measurement unit
14

Operating guidance
your required (CMS, CMM, CFM).
4.9 Temperature unit selection
Long press the “UNIT” key for 3 seconds to switch
temperature unit (°C , °F ).
4.10 Temperature mode selection
Long press the “HOLD/MODE” key for 3 seconds to
switch temperature mode (ambient temperature, dew point
temperature and wet bulb temperature).
4.11 USB real time data uploading
Long press the “ /USB” key for 3 seconds to enable
or disable USB real time data uploading function.
Detailed steps are shown as follows:
1．Use CD to install the PC software and the USB drivers.
2．Power on the meter and connect it to a computer with
USB cable.
3．Launch the PC software.
4．Long press the “ /USB” key for 3 seconds to enable the
USB function of the meter.
5．The PC software displays data and diagrams.
6．Save or print data.
