To disable the auto power off function, you must power the

meter off and then power it on in the following special way.

Press and hold the HOLD button while pressing the ON-OFF

RESET button once. Continue pressing and holding the HOLD

button until the beeper sounds and the meter powers on with

the display shown in Fig. 10.

Fig. 10. The display indicating that the auto power off

function has been disabled.

This display will last for only a few seconds. The meter will

then switch to its “normal” operating mode: measuring and

displaying real-time air speed values.

Bear in mind that with auto power off disabled, powering off

the meter by pressing the ON-OFF RESET button undoes the

disabling. The next time the meter is powered on, the auto

power off function will be enabled.
