Installation

• Unpack the anemometer with care.

• Open the battery door. Then install three 1.5 volts “aaa” size or equivalent

• Battery into the battery compartment. And close the battery door.

• Replace new battery when the low battery indicator appears on the screen.

Operations

ON/OFF:

Press “on/off” for on/off switching. Full display shows for a while. the upper display shows the velocity (default as m/s) velo sign appear, while the lower display shows the temperature (default as °f) measured.

One hour auto shut off function & cancellation:

This product will turn off automatically after one hour, to disable this function, press “on/off” and “h/t” together to turn on the unit each time. The product will keep working until being shut off by users.

Unit:

The unit is default in ft/min as measurement unit for air velocity. User can press this button to interchange the airflow velocity unit as the following: ft/min > mph > m/s > km/hr > knots.

Hold/Test:

Press the button to freeze the reading for recording (both velocity & temperature), hold sign appears. Press again the unit will restore to real time mode.

°F/°C:

Press to switch the reading between °c and °f as temperature unit.

Avg./max/min reading for continue moving average measurement (single point):

• a) Press once the unit will show the continue moving average measurement of velocity (avg.), maximum measurement (max) and minimum measurement (min) as following:

          avg > max(both temp & velocity) > min(both temp & velocity) > real time reading.  

• b)  Relevant sign appears on the display and reading update per seconds.  

• c)  To clear value, press and hold the key for 3 seconds, 2 successive beeps sound is given out.

Avg. (multi point):

• a) hold the unit in position, press the “hold” button to freeze the reading (both velocity and temperature).

• b) Then press “mem” button to save the reading. (a single beep is given out for every successful saving). Mem 1 displays representing one reading is saved.

• c) Repeat step (a) – (b) to save another reading, mem 12 displays representing 2 readings are saved.  

• d) Continue to do so up to 10 sets of reading can be saved.

• e) Once all measurement have been saved, press “avg. (multi point)” button, the unit will display the average air velocity from memory and avg. sign appears.

Mem. (Memory recalling):

• a) Press the “mem” button, all saved reading (both temperature & velocity) will be shown, starting from the 1st reading (i.e. mem 1) to the 10th reading (i.e. mem 10).  

• b) Press and hold the “mem” button for 3 seconds to clear all saved readings. Air flow volume measurement.

(i) Single point measurement:

• a) Determine the free area of the air source.

• b) Press “air flow” button for 3 seconds to define free area, displays shows area sign and first digit of 1.111 sq feet flashes.

• c) Press “hold” button to increase number of the flashing digit.

• d) Press “avg. (multi point)” button to move to the next digit.

• e) Press the “air flow” button, the defined free area is saved and the unit is now ready to measure air flow (CFM) and flow sign appears. Value shows on the upper display.

(i) Average for multi point measurement:

Press and hold the “avg. (multi point)” button for 3 seconds to clear current average readings in the velocity/fpm mode.

• a) Repeat (a) to (e) in section (g) to determine all multi-point average reading.

• b)  Press “air flow” button for 3 seconds and unit enters to the free area setting.

• c) Repeat step (a) to (e) in section (ii) to default free area setting.

• d) Press “air flow” button to confirm and unit enters to the CFM mode. The unit display average air flow reading and number of points measured. value shows on the upper display.
