The meter will perform a short self-test. A. Air Velocity Measurements 1. Press the Function button to select the Anemometer mode. In Air Flow mode, the display will show Air Velocity and Temperature. 2. Press Unit/Zero button to select desired unit of measure (FPM, MPH, KNOT, KM/H, or M/S) and face the Air Flow Sensor towards the source of wind. 3. Allow time for the reading to stabilize and note value. From a practical point of view the velocity may fluctuate slightly. B. Humidity and Ambient Air Temperature Measurements 1. Press the Function button to select RH mode.. In RH mode, the display will show %RH and Temperature. 2. Press the °C/°F button to select the desired temperature unit of measure. C. Temperature Measurements Using Type K Thermocouple 1. Press the Function button to select the Temperature mode. In Temperature mode, the display will show only temperature. 2. Plug the thermocouple into the meter's thermocouple input jack. If no thermocouple is connected, or if the thermocouple is defective, the meter will ----display “ “. (Primary display temperature will only work if a thermocouple is connected). D. Light Measurements 1. Press the Function button to select the Light Meter mode . The light values are displayed and orientated 180° from the other functions for easy use. 2. Press the Lux/Ft-cd to select Lux or Footcandle units of measure. 3. Before making measurements “Zero” the meter out by blocking the light sensor to simulate a no light condition and pressing the Unit/Zero button.The reading should go to Zero. 4. Hold the sensor toward the light source and note reading. MIN, MAX, Data Recording Function 1. Press the Max/Min button once. The RECORD symbol will appear on the display.This starts the Min/Max Data Recording Mode. 2. Press the Max/Min again and the MAX symbol along with the maximum value will appear on the display. 3. Press the Max/Min once more and the MIN symbol along with the minimum value will appear on the display. 4. To Clear the recorded Max/Min values press the HOLD button once. Press and Hold the Max/Min button for 3 seconds to exit Min/Max Data Record Mode and return to normal measurement mode. Record and Max/Min will disappear from the display once this is done. 3 45170 V1.1 5/09 Data Hold Press the HOLD button to freeze the reading in the display. The 'HOLD' icon will appear on the upper right-hand side of the display. Press the HOLD button again to return to normal operation (the 'HOLD' hold icon will disappear). Auto Power OFF The meter will automatically turn off after 10 minutes if no keys are pressed during this period. Auto power off is disabled in the max/min recording mode. Turning Power OFF Press the power button to turn power off. Calibration and Repair Services Extech offers repair and calibration services for the products we sell.
