4.Operation
Connecting the Vane
• The vane plug is inserted in the meter's sensor jack at the top of the meter. The plug and
jack are keyed so that the plug can only fit in the jack one way.

twice) to save the area into memory and return to CFM or CMM measuring mode.
Data Hold (Air Velocity/Air Flow)
• While taking measurements, press the HOLD button to freeze the air velocity/air flow
reading.
• The HOLD indicator will appear in the bottom of the LCD display.
• Press HOLD again to return to normal operation
MAX/MIN/AVG Record (Air Velocity/Air Flow)
This allows the user to record and view the highest (MAX), lowest (MIN) and average (AVG)
readings.
• Press the button MAX/MIN button. The MAX indicator and RECORD indicator along with
the Max reading will appear on the LCD display and the meter will begin keeping track of the
