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.

Func. key - Back light control

1. Press and hold the

FUNC.

key for 1 sec. The back light will be turned on.

2. Press and hold the

FUNC.

key once again for a 1 sec. The back light will be
