If the vane is nt cnnected t the meter r if the sensr is defective, the LCD display will indicate OL in place f a Temperature reading. Air Velcity Measurements (Single Pint) 1. Turn n the meter using the ON/OFF buttn. 2. Press UNITS buttn t select the desired unit f measure. NOTE: At pwer up the meter will display the last unit f measure previusly entered. 3. Place the sensr in the air stream. Ensure that the air enters the vane as indicated by the arrw sticker placed inside the vane. 4. View the readings n the LCD Display. The large main LCD display shws the Air Velcity reading. The upper right LCD sub display shws the temperature reading. Air Velcity Averaging Mde Side view f Vane Arrw airflw 1. T enter 20 Pint Averaging Mde, press and hld the AVG buttn until it beeps twice. The AVG icn will be displayed. 2. Take a measurement and press the AVG buttn. A single beep will sund and the HOLD icn will appear in the display. 3. The average reading will be displayed and number f readings measured will appear in the upper right hand crner f the display. After 5 secnds, the display will return t the current reading. 4. Repeat steps 2 3 until the desired number f pints have been measured. 5. T return t standard velcity measuring mde press and hld AVG buttn until meter beeps twice. Nte: In the standard velcity measuring mde, press the AVG buttn nce t recall the previus average. The average will be cleared when yu enter the Averaging Mde again. 5 AN100-EN V3.3 6/13

6 Air Flw Measurements (CMM / CFM) 1. Turn n the meter using the ON/OFF buttn 2. Press the UNITS buttn t select the desired air flw units: CMM (cubic meters per minute) r CFM (cubic feet per minute). NOTE: At pwer up the meter will display the last unit f measure previusly entered T begin entering the area in m r ft, press and hld the AREA buttn until it beeps twice. The leftmst digit f the bttm display will begin t flash. 4. Use the (UP) buttn t change the flashing digit Use the (LEFT) buttn t mve the decimal Use (RIGHT) buttn t select the ther digits. Side view f Vane Arrw airflw After all f the digits are entered, press and hld the AREA buttn (until meter beeps twice) t save the area int memry and return t CFM r CMM measuring mde. 5.
