Insert the vane plug into the meter’s sensor jack at the top. Turn it carefully until it lines up and push firmly. Do not twist or apply undue force.
Press and hold the AVG button until it beeps twice. Take measurements and press AVG to store each reading. After 5 seconds, the display returns to current reading. Press and hold AVG again to return to standard mode.
Disconnect the sensor, remove the rubber jacket, open the battery compartment with a Phillips screwdriver, replace the 9V battery, and close the compartment and jacket.
