Press the SAMPLE RATE key to change the measurement averaging rate
(“sample rate”) of the unit:

An average value of airspeed measurements during the preceding 8 seconds is
displayed.
16 s
An average value of airspeed measurements during the preceding 16 seconds is

Press the MAX/MIN key to record and display the maximum airspeed reading.
The maximum airspeed reading display will alternate with the letter “H”
displayed with the sample rate. Press the MAX/MIN key again to record and
hold the minimum airspeed reading. The minimum airspeed
reading display will alternate with the letter “L” displayed with the sample rate.
For example:
1065
alternating with
h 8
signifies that 1065 is the highest airspeed reading since
the MAX/MIN key was pressed, and the sample rate is set to 8 seconds.
82
alternating with
l 16
signifies that 82 is the lowest airspeed reading since the
MAX/MIN key was pressed, and the sample rate is set to 16 seconds.
