DISPLAY MODES

The meter may be set to the following display modes:

Anemometer Current Air Speed

(Anemometer reading shown is the current air speed being

measured.)

Anemometer Maximum Air Speed (MAX)

(Anemometer reading shown is the maximum air speed achieved.

“MAX” appears on the display.)

Anemometer Average Air Speed (AVG)

(Anemometer reading shown is the average air speed. “AVG”

appears on the display.)

SELECTING THE DISPLAY MODE

1. Press the MODE button for 2 seconds to turn
the meter on.

2. Press and hold the MODE button, after

approximately ve (5) seconds, the unit of
measure will ash on the display.

3. Press the SET button to cycle through the

available units of measure:
(m/s→km/h→ft/min →knots→mph) after the
units of measure, the display modes will appear
(CU→MAX→AVG)

BEAUFORT SCALE GRAPHIC DISPLAY

While taking airow measurements, the display will

automatically graphically display the Beaufort Wind

Scale value for the airow being measured.

Value ....Wind (Knots) .....WMO Classication

0 .................>1 .............. Calm

1 ................ 1-3 .............. Light Air

2 ................ 4-6 .............. Light Breeze

3 ............... 7-10 ............. Gentle Breeze

4 .............. 11-16 ............Moderate Breeze

5 .............. 17-21 ............ Fresh Breeze

6 .............. 22-27 ............ Strong Breeze

7 .............. 28-33 ............ Near Gale

8 .............. 34-40 ............ Gale

9 .............. 41-47 ............ Strong Gale

10 ............. 48-55 ............ Storm

11 ............. 56-63 ............ Violent Storm

12 ...............64+ ............. Hurricane

AUTOMATIC SHUTOFF

If no button has been pressed, and no airow is

being measured, after fourteen (14) minutes, the

Automatic Shutoff feature will turn the meter off to
preserve battery life.

To manually turn the meter off, press the MODE
and SET buttons simultaneously.

BACKLIGHT

Press and release either the MODE button or SET

button to activate the display backlight. The back­light will illuminate the display for 12 seconds.

Frequent use of the backlight will greatly reduce

the battery life.

ALL OPERATION DIFFICULTIES

If this meter does not function properly for any

reason, replace the battery with a new, high quality

battery (see the “Battery Replacement” section).

Low battery power can occasionally cause an
number of “apparent” operational difculties.
Replacing the battery with a new fresh battery will
solve most difculties.

BATTERY REPLACEMENT

An erratic display, faint display, “
or no display are all indicators that the battery

needs replacement. Remove the battery cover
screw located on the back of the unit. Remove the
battery cover. Remove the exhausted battery and
replace it with a new CR2032 lithium battery. Make
certain to insert the new battery with the “+” side up.
Replace the battery cover. Replace the battery
cover screw and tighten securely.
