Velleman DVM9500 - Manual

Hand held Anemometer
Operating Manual
Introduction:
Congratulations on purchasing this pocket-sized anemometer, this innovative product provides
wind speed, wind chill and temperature information for any outdoor activities. The operation of
this product is simple and straightforward and by reading this operating manual, users will
receive the optimum benefits of all its features.
The Anemometer
Features:
• Wind speed measure in mph, Km/h, m/s or Knots
• Wind speed in Beauford wind scale bar graph
• Wind chill display
• Temperature display in degrees Celsius or Fahrenheit
• LCD back-light
• Auto power OFF
• Neck band included
• Water resistance
Setting up:
1. Firstly, use a large coin to open the battery
cover at the back of the anemometer as
indicated above.
2. Checking the correct polarization, insert
1 x 3V (CR2032) lithium cell, positive (+) pole up
into the battery compartment and replace the
cover.
3. When the battery is inserted, all the segments of
the LCD and back-light will light up briefly.
Your anemometer is now operational.
Note:
After inserting the battery, test the anemometer by blowing directly at the Impeller for about 30
seconds. The reading on the LCD should change. If it is not the case, remove the battery. Wait
for 30 seconds, and re-insert the battery again.
Function keys:
The anemometer uses the following keys:
MODE/ ~ key : To toggle between wind speed and temperature/wind chill display
: Power ON/OFF
: To enter the setting node
: Back-light-On
+ Key : To change operation mode
(PLUS) : To change parameter in setting mode
: Back-light-On
Selection of operation mode
There are two modes, one is wind speed, and another is temperature. By pressing the
“MODE/
~” key the display will toggle between wind speed and temperature/wind chill
Wind speed Mode
The wind speed mode can be selected into 3 different displays at any time.
To toggle between current wind speed, maximum wind speed and average wind speed, simply
press the “+” key:
Beaufort wind
scale (bft)
The Beaufort scale is
displayed in bar graph
(0-12). This is a system
for estimating wind
force without the use of
instruments based on
the visible effects of the
wind on the physical
environment.
Temperature and Wind chill Mode
The Temperature and wind chill modes can be selected into 2 different displays at any time.
Temperature Wind chill
By pressing the “+” key the display will toggle between temperature and wind chill.
When the temperature is outside the range from –29.9°C to +59°C, there will be no wind chill
measurement.
Wind chill
The anemometer calculates automatically wind chill, which can provide useful information for
preparing outdoor activities in cold weather. “Wind chill” provides an indication of how cold it feels
given the combined effects of the actual air temperature and the wind speed.
Power ON/OFF:
Press and hold down the “MODE/ ~” key for 2 seconds to switch ON/OFF.
Note:
The anemometer is automatically switched OFF when no key is pressed in 34 minutes.
Manual setting
Before entering the manual setting mode, switch off the anemometer.
Press and hold down the “MODE/
~” key for about 4 seconds, the speed unit will start flashing
on the LCD when the manual setting mode is entered.
Measurement scale setting
1. After entering the manual setting mode, press “+” key to set the measurement scale in
Km/h (Kilometers per hour), mph (miles per hour), m/s (meters per seconds) or Kts
(Knots).
2. Now press the “MODE/ ~” key to confirm and enter the “°C and °F setting”.
°C and °F setting:
1. Following from the measurement scale Setting °C will be flashing, use the “+” key to toggle
°C and °F.
2. Once the desired temperature unit has been chosen, press the “MODE/ ~” key to confirm
and enter the “Average time for current speed measurement setting”.
Average time for current speed measurement setting
The current wind speed can be measured in average wind speed in a time interval 2-10 seconds
1. Following from the °C and °F Setting, press “+” key to set the desired average time. The
range runs from 2 to 10 seconds.
2. Once the desired average time has been chosen, press the “MODE/ ~” key to confirm
and back to the normal mode.
LCD back-light:
The LCD back-light is automatically switched ON when any one of the 2 function keys are
pressed and held down about 2 seconds. The back-light will be switched on for approximately 8
seconds before automatically switching OFF.
Fastening the necklace
The carry necklace is supplied with the anemometer.
To fasten, simply insert the clip of the necklace into the buckle end
of the anemometer until it clicks into place.
To unfasten, simply press both sides of the clip until it can be
removed from the buckle.
Battery change:
It is recommended to replace the battery in the unit on an annual basis to ensure optimum
accuracy of this unit.
Please help in the preservation of the environment. Return used batteries to an
authorised depot.
Maintenance:
• Avoid placing anemometer in areas prone to vibration and shock as these may damage and
inaccurate readings.
• Avoid exposure to sudden changes in temperature such as direct sunlight, extreme cold and
wet or moist conditions.
• When cleaning the display and casing, use a soft damp cloth only.
Do not use solvents or souring agents as they may mark the LCD and casing.
• Do not make or attempts to make any repairs to the anemometer. Return it to its original point
of purchase for repair by a qualified engineer. Opening and tampering with the unit may
invalidate its guarantee.
