Digital Thermometer and Vane Anemometer
1. GENERAL INSTRUCTIONS
Thank you for purchasing the Edison Digital Temperature and Vane Anemometer.
To get the best service from this instrument, read carefully this user manual and
respect the detailed safety precautions.
This meter is a flow/temperature measuring instrument. It is idealy used to
measure air speed at ventilation outlets and to test temperatures in residential
and commercial environments such as offices, storerooms, greenhouses and
places where climatic conditions can also be analysed.
1.1. Precautionary safety measures
To get the best service from this meter, please read this manual carefully.
1.2. During use
• If the ‘O ’ symbol appears on the CD, it means the reading is outside the
measuring range. Please keep to the permitted measuring range.
• NEVER store the product together with solvents, acids or other aggressive
substances.
• When the battery voltage is under a sufficient operation level, the symbol
will show on the CD. The batteries will need to be replaced with new.
1.3. Maintaining the product
• DO NOT measure in high temperature, high humidity places.
• Air flows through the meter from the rear to the front.
• When not using the instrument for a long time, please remove the batteries
and avoid storing in high temperature and high humidity.
• DO NOT try to unscrew the vane sensor.

4. Operation Instruction
• To ensure the accuracy of the measured readings, all interference sources
which may affect the measurement results for airflow/temperature (such as
the hand or obstructions) must be clear from the sensor.
• To guarantee correct readings: position instrument so that air flows through
from the rear to front of the meter with the vane at 90° to the wind direction.
4.1. ON/OFF
1. First remove the meters protective sensor cover.
2. Press the ON/OFF key to turn the power ‘ON’.
3. The CD will display the current value of vane speed and temperature.
Default setting is m/s / °C (meters per sec./temperature).
4. To turn the meter ‘off’ press the ON/OFF key.
4.2. Unit key
This key sets the unit of airflow and temperature required for testing.
1. When the meter is switched ‘on’ p
ress the UNIT key to change through the
6 different
airflow settings available for measuring.
2. Settings are as follows:
m/s = meters per second (Default setting)
km/s = Kilometres per second
fpm = Feet per minute
mph = Miles per hour
kts = Knots per second
Beau = Beaufort scale
3. Temperature can be measured in both °C and °F.
4. To change between temperature settings from °C (Default) to °F, press and
hold the
UNIT
key for 1 sec. To change back to °C press and hold the
UNIT
key for 1 sec.
4.3. Func. key
1. When the meter is switched ‘on’ and the required unit has been set p
ress the
FUNC. key to
display the
‘HO D’,
Maximum or Minimum readings, this is
acknowledged with the symbol on the CD display.
2. To cancel the
‘HO D’
‘MAX’ or ‘MIN’ , readings press the
FUNC.
key until the
symbols no longer appear on the CD Screen.

5.1. CLEANING INSTRUCTIONS
The meter may be wiped down with a wet sponge or cloth using a mild water
based detergent or anti-bacterial soap and rinsed under a gentle stream of cold
water.
NOTE: This unit is not designed for complete submersion or washing in water.
5.2. BATTER REPLACEMENT
Use the following procedure:
When the battery voltage drops below the required operation range the
symbol will appear on the CD display and the batteries need to be replaced.
1. On the back of the meter, slide the battery cover in the direction of the
arrowhead to open the battery cover.
2. Replace the batteries with 3 new 1.5V batteries (AAA).
3. Replace the battery cover.
