Air Flow Measurement

AIR FLOW = (AIR VELOCITY) x (AREA)
• Push key to turn on the meter.
• The display will show the air velocity reading directly on the air velocity
display.
• The flow type setting is displayed on the flow set up display.
• Push "FLOW" key to select the desired 2/3V MAX mode, AVG mode or
current mode.
If 2/3V MAX mode is chosen, the "2/3V MAX" symbol will displayed. The
meter will use the maximum air velocity value obtained to determine the
2/3V MAX Air Flow.
If average mode is chosen, the "AVG" symbol will displayed. The meter
use air velocity average value (the last 30 samples) obtained to determine
the Average Air Flow.
If current mode is chosen, no symbol will displayed. The meter will use
the current air velocity value obtained to determine the Current Air Flow.
• The display will show the air flow reading directly on the Air Flow Display.

MAX/MIN/AVG Recording Measurement

• Push "MX/MN" key to enter the recording mode, the " REC " symbol is
displayed and the auto power off function will be auto cancelled.
• Push "MX/MN" key to circulated the display of the maximum ( REC MAX
), minimum ( REC MIN), average ( REC AVG ) and current ( REC ) air
velocity reading.
• Push " H HOLD" key to paused recording, the " H " symbol is displayed,
push " H HOLD" key again will resume recording.
• Push "MX/MN" key for 2 seconds to exit this mode.
