1. FEATURES
* The portable anemometer provides fast, accurate
readings, with digital readability and the convenience of a
remote sensor separately.
* Multi-functions for air flow measurement: m/s, km/h,
ft/min, knots.
* Low-friction ball-bearing design allows free vane
movement, resulting in accuracy at both high & low
velocities.
* A sensitive balanced vane wheel rotates freely in response
to air flow.
* Conventional twisted vane arms, always a source of
unreliability have been eliminated.
* DATA HOLD function for stored the desired value on
display. Large LCD display, easy to read.
* LCD display for low power consumption & clear
read-out even in bright ambient light condition.
* Used the durable, long-lasting components, including a
strong, light weight ABS-plastic housing case.
* Compact housing cabinet, easy to carry out.
* Built-in low battery indicator.
* Wide applications: use this anemometer to check air
conditioning & heating systems, measure air velocities,
wind speeds, temperature...etc.

4. MEASURI NG PROCEDURE
1) Select the " Off/On/Hold Switch " ( 3-2, Fig. 1 ) to the
" On " position.
2) Select the " Function Switch " ( 3-3, Fig. 1 ) to the " m/s ",
" km/h ", " ft/min " or " knots " position according to the
measuring requirement.
3) Hold the " Vane Probe Handle " ( 3-5, fig. 1 ) by hand &
let the " Vane Probe Head " ( 3-6, Fig. 1 ) is opposite to
the measuring air flow source, then the Display ( 3-1,
Fig. 1 ) will show air velocities directly.
Measuring Consideration :
The yellow dot mark on the sensor head indicates the
" yellow dot mark " need to face against the direction of
air flow.
4) During the measurement, it will hold the display values if
select the " Off/On/Hold Switch " ( 3-2, Fig. 1 ) to the
" Hold " position.

5. REPLACEMENT OF BATTERY
1) When the left corner of LCD display show " BAT ", it is
necessary to replace the battery. However, in-spec.
measurement may still be made for several hours after
low battery indicator appears before the instrument
become inaccurate.
2) Loose the " Battery Cover Screw " ( 3-4, Fig. 1 ), slide
the battery cover away from the instrument and remove
the battery.
3) Replace with 9V battery ( heavy duty type ) and reinstate
the cover.
4) Make sure the battery cover is secured with the screw after
changing battery.
