How to operate:
Operang mode introducon
1. Turning On and O your Meter
a. Press the Power Buon for over 2 seconds to turn on
your meter. Aer 10 minutes without any operaon the
meter will power o.
b. To override the Auto Power O hold down the Set
Buon then press the Power Buon to turn on. You will
see the Power Symbol appear on the LCD. Warning, the
meter will stay on unl the baery runs out unless you turn
o by holding down the Power Buon.
2. Max/Min/Avg Value Measurement Funcon
In any measurement mode quickly press the Power Buon
to choose Maximum Reading, a second press will display
the Minimum Reading, a third press will display the Average
reading and a forth press will return the meter to the stand-
ard current readings.
Max: When is this mode the meter will display the maxi-
mum value reached
Min: When is this mode the meter will display the mini-
mum value reached
AVG: When is this mode the meter will display the average
value reached
*Once the meter is switched on it will start to record the
Max/Min/Avg values*
Press SET Buon to change the display modes:

Trouble Shoong
1. The Meter is displaying the wrong readings
Enter the calibraon mode and correct using a known trusted source
such as a reputable internet source for Barometric and Altude
Readings. Or a known accurate stable air ow will need passing
through the meter vane in working mode (an accredited wind ow
tunnel is strongly recommended), to assist in calibrang the wind
speed.
2. Power on but no display or the display disappears
a. Check the baery is in place with good contact to the pins and
the correct way up.
b. Remove baery for one minute and re-install.
c. Replace the baery.
3. For all other issues please contact your supplier.
Relave Altude Measurement
To view the relave altude, or the change in altude since
last calibraon (referred to as climb or ascent / descent),
press and hold the Units Buon for two seconds, the LCD
will then display the REL interface on screen and then rela-
ve altude (Defaulted value 0m). The value on the screen
will change as the Anemometer is moved higher or lower
than its current posion. Press and hold the Units Buon
again for two seconds to change back to Absolute (Density)
Altude. Please see below picture:
Baery Replacement
If the meter does not power on as usual or the low baery
icon appears on the LCD display, please replace the
baeries with a new 9V baery as soon as possible.
Dispose of the baery in an environmentally safe at a recy-
cling point.
DO NOT DISPOSE IN YOUR DUST BIN!
Calibraon funcon
Step 1.Hold Units Buon then turn on meter to enter cali-
braon mode.
Step 2: Press Units buon choose the mode “see table
below”, then press Power Buon to enter the calibraon
mode;
Step 3: Press Units Buon to choose the unit you wish to
change (the selected unit will ash quickly) and press Set
Buon to adjust to the correct value,
Step 4: Press Power Buon for over 2 seconds to store the
seng and exit.

Cauon:
1. This meter is accurate at low and mid-range air speeds. Consistent
use at very high speeds, i.e. from the window of a fast moving car
will damage the impeller’s bearing and reduce accuracy.
2. This meter is not a personal safety device.
Warranty
This meter has a one year warranty for a period of one year from
purchase date.
This warranty covers normal operaon and does not cover baeries
(including leaks), misuse, abuse, alteraon, tampering, neglect, im-
proper maintenance or improper calibraon. Nor can the warranty be
used as an excuse for a false claim simply because you have changed
your mind aer the inial 14 day period.
Proof of purchase is required for warranty repairs.
