5. Operation
5.1 Installing Batteries
This product requires 3 × 1.5V AAA batteries (not supplied).
To install the batteries, slide the battery compartment
cover (1) down and away from the back of the device and
insert the batteries according to the correct polarity.
5.2 Switching On and Basic Operation
To switch on the device, press and hold the power button
(5) for one second. The device performs a diagnostics
check during startup before readings are shown on the
display.
Hold the device so that the wind passes directly through
the front face of the wind vane (8) (the same side as the
display). For best results, hold the device at arm’s length
from your body.
The device begins measuring air velocity and temperature
immediately and the readings are indicated on the display
(2). Readings are updated every 300ms.
To switch o the device, press the power button. This resets
the device.
5.3 Freezing the Display
The current readings can be held on the display by pressing
the hold button (3). The hold data indicator (13) illuminates
to show that the display has been frozen.
Important: While data is held on the display, no other
measurements are taken and the units of measurement
cannot be changed. If the unit button (x) is pressed while
the screen is frozen, the air velocity reading units will
update as appropriate when the screen is released.
To resume measurements, press the hold button again. The
hold data indicator is hidden and the display updates in
real-time.
5.4 Maximum and Minimum Values
The display can be set to show the maximum or minimum
value recorded for both air velocity and temperature during
an active session.
Press the min/max button to display the maximum value
recorded. Each subsequent press of the min/max button (4)
alternates between the highest and lowest values recorded
since the device was switched on. The max (14) or min (15)
value indicators illuminate as appropriate to identify the
value shown on the display.
Important: While min/max mode is active, no other
measurements are displayed unless they exceed the min or
max reading currently shown on the screen. These new
readings are then locked until they are surpassed by new
data. The units of air velocity measurement can be changed
while this mode is active.
To exit min/max display mode, press and hold the min/max
button for three seconds.
5.5 Air Velocity Reading Units
To change the unit of the air velocity reading, press the unit
button (7). Each press of the button advances to the next
unit of measurement.
5.6 Temperature Reading Units
The unit of the temperature reading can be changed during
startup.
Important: Ensure the correct unit of measurement for
temperature is enabled before capturing meaningful
readings as all readings are lost when the device is
switched o.
While the device is o, press and hold the hold button (3).
Keeping the hold button depressed, also press the power
button (5) to switch on the device. The device will launch
with the other temperature units enabled.
The default unit for temperature measurement is degrees
Celsius.
5.7 Automatic Switch-O
By default, the device is congured to power o
automatically after approximately 15 minutes of inactivity.
If automatic switch-o function is enabled, the auto-o
indicator (11) is illuminated on the device display.

hold the unit button (7) while the device is o and, keeping
the unit button depressed, also press the power button (5)
to switch on the device. The device will launch with the
function disabled.

only to the current active session. Automatic switch-o is
automatically enabled the next time that the device is
switched on.
Important: If automatic switch-o is disabled, the device
can only be powered down by pressing the power button.
5.8 Low Battery Warning
An approximate indication of the device battery level is
shown in the corner of the display. When the battery level
indicator (12) is empty, the batteries must be changed.
Important: Low power to the device may aect the
accuracy of the measurements displayed.
6. Maintenance and Disposal
Important: Other than the batteries, this product has no
user-serviceable parts; however, regular product care will
