AVG = Press to obtain an average reading for
multiple points in Flow mode or Velocity
mode. Up to 20 points can be aver
aged.
AREA = Press and hold to enter into the Area
mode (ft 2 or m 2 ) in CFM (ft 3 /min) or
CMM (m 3 /min) modes. When recording
MAX/MIN/AVG readings for a single
point, press the Area button to clear
previous readings.
HOLD = Press once to freeze the displayed
reading. Press again to unlock display.
= Press to turn ON the backlight. Press
again to turn OFF.
MAX/MIN (TEMPERATURE) = Press to record
and store the highest and lowest readings for probe
temperature.
HOLD (TEMPERATURE) = Press to freeze the
displayed reading for probe temperature. Press again
to unlock display.
