Connect the sensor to the sensor input jack on top of the meter. 2. Turn on the meter using the Power button. 3. Select the VELOCITY function using the FLOW / VELOCITY button. The LCD will display VEL when the velocity mode is selected. 4. Select the desired temperature units using the C/F select button. The LCD will reflect the current unit selection. 5. Select the desired air velocity units using the UNIT button. The LCD will reflect the current unit selection. 6. Place the sensor in the air current to be measured with the symbol on the inlet side of the vane (see diagram). Air Direction 7. View the air velocity and temperature readings on the LCD Display. The large main LCD display shows the Air Velocity reading. The lower LCD sub-display shows the temperature reading. Data Hold 1. While taking measurements, press the HOLD button to freeze the LCD reading. 2. The HOLD indicator will appear on the LCD when the display is in Data Hold mode. 3. Press HOLD again to return to normal operation. Maximum and Minimum Recording The 407113 allows the user to record and view the highest (MAX) and lowest (MIN) readings. 1. Press the RECORD/RECALL button once. The REC indicator will appear on the display and the meter will begin recording the MAX and MIN values. 2. Press the RECORD/RECALL button to stop the MAX/MIN recording and display the maximum reading. The MAX indicator along with the maximum reading will appear on the LCD display 3. Press RECORD/RECALL again to view the minimum value. The MIN indicator along with the minimum reading will appear on the LCD display. 4. To return to normal operation, press and hold the RECORD/RECALL button for approx. 3 seconds. The display indicators REC, MAX, and MIN will disappear. NOTE: Placing the meter in the RECORD/RECALL mode by pressing the RECORD/RECALL button disables the AUTO POWER OFF feature. NOTE: Handle the vane carefully. If the metal vane blades are inadvertently bent or damaged erroneous readings may result. 5 407113-EN v3.6 4/14 Air Flow (Volume) Measurements (CMM / CFM) 1. Connect the sensor to the sensor input jack on top of the meter. 2. Turn on the meter using the POWER button. 3. Select the FLOW mode using the FLOW/VELOCITY button. The LCD will display FLOW CFM or FLOW CMM when the flow function has been selected. 4. Select the desired air flow units: CMM (cubic meters per minute) or CFM (cubic feet per minute) using the UNIT button. The LCD will reflect the selection. 5. Measure the dimensions of the duct or vent and calculate the area in square feet or square meters Note: If the dimensional measurements are made in inches (or cm), convert them feet (or meters) before calculating the square area. 2 2 button to increment 6. Press the AREA button to begin entering the area in m or ft . Use the the flashing digit, use the button to decrement, use the button to select the next digit, and use the button to set the decimal point. 7. Press the ENTER/RESET button after the area value has been entered. The bottom display will 2 2 indicate the area entered in ft or m . The main LCD displays the Air Flow in CFM (cubic feet per minute) or CMM (cubic meters per minute). If the CFM or CMM reading exceeds 9999, use the displayed X10 or X100 multiplier to calculate the reading. 8. Note that for FLOW measurements, three modes apply: The normal, default mode, where the actual flow is indicated and the two modes described below under 2/3 MAX Flow and AVG Flow. Note: The temperature function is not active in the FLOW mode. 2/3V MAX Flow Mode In this mode the meter will display two-thirds the measured Flow (Volume). To access this mode, ensure that the meter is in the FLOW mode (via the FLOW/VELOCITY button) and then press the FLOW MODE button until the 2/3V MAX display icon appears. Now the Flow display will be 2/3 the actual measurement. To return to the normal display mode, press the FLOW MODE button until the 2/3VMAX and the AVG icons switch off. AVG (Average) Flow Mode In this mode the meter will display the AVERAGE Flow for up to 20 readings. To access this mode, ensure that the meter is in the FLOW mode (via the FLOW/VELOCITY button) and press the FLOW MODE button until the AVG display icon appears. Now each time the AVG/START button is pressed a reading will be taken and averaged. The lower LCD display becomes a 20-reading counter and with each reading taken the counter is incremented. Allow 3 or 4 seconds between AVG/START button presses for the display counter to update. The main LCD displays the averaged Air Flow value. To return to the normal display mode, press the FLOW MODE button until the AVG icon switches off. RS-232 PC Interface The 407113 is equipped with a 3.5mm phone jack (meter top) for connection to a PC for data acquisition purposes. For streaming of data to a PC via the RS232 Output jack, the optional 407001-USB kit (RS232 to USB cable and driver CD) along with the 407001 software (available free at www.extech.com) are required. Instructions for use are provided with the data acquisition software/hardware kits. 6 407113-EN v3.6 4/14 Battery Replacement When the LBT icon appears on the LCD, the 9V battery must be replaced. 1. Remove the rubber holster that surrounds the entire meter 2. Slide off the rear battery compartment 3. Replace the 9V battery 4. Affix the battery compartment cover and the meter holster Useful Equations and Conversions Area equation for rectangular or square ducts Height (H) Area (A) = Width (W) x Height (H) Width (W) Area equation for circular ducts Area (A) = pi x r2 Where pi = 3.14 and r2 = radius x radius Radius Cubic equations CFM (ft3/min) = Air Velocity (ft/min) x Area (ft2) CMM (m3/min) = Air Velocity (m/sec) x Area (m2) x 60 NOTE: Measurements made in inches must be converted to feet or meters before using the above formulae.
