EDI-312-4020K_Instructions_Layout 30/04/2015 15:06 Page 3 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 OL symbol appears on the LCD, 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 LCD. 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. 3

EDI-312-4020K_Instructions_Layout 30/04/2015 15:06 Page 6 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 LCD 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 press 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 press the FUNC. key to display the HOLD, Maximum or Minimum readings, this is acknowledged with the symbol HOLD MAX MIN on the LCD display. 2. To cancel the HOLD MAX or MIN, readings press the FUNC. key until the symbols no longer appear on the LCD Screen. 6
EDI-312-4020K_Instructions_Layout 30/04/2015 15:06 Page 7 Digital Thermometer and Vane Anemometer 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 turned off. NOTE: If the back light is not closed within 60 seconds, it will turn off automatically. 4.5. Auto power off setting When the meter is powered on, it is under auto power off mode. This means the meter will power itself off after 20 minutes if no keys are operation. To override the auto power off mode follow the following instruction: 1. Press and hold the ON/OFF key until the LCD display AP ON. 2. Press the UNIT key to select AP ON or AP OFF. 3. Then press the FUNC. key to confirm the setting. AP ON = Auto power off activated. AP OFF = Auto power off deactivated. 4. To revert back to the default setting switch the meter off and on again. 5. Maintenance 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. BATTERY REPLACEMENT Use the following procedure: When the battery voltage drops below the required operation range the symbol will appear on the LCD 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. 6. PACK CONTENTS Digital multimeter Wrist strap Instruction manual DC1.5V x3 AAA batteries (installed) Carry Case 7
