4.4.2 F - Fast Mode
This option is the enable for putting the H-3531 FlashLite™ in a special mode called Fast
Mode. Fast Mode causes the H-3531 FlashLite™ to complete measurements in 1 second
vs. the normal mode which takes about 6 seconds. This mode is not recommended
because the atmospheric pressure and temperature values are only updated every 3 minutes
and the H-3531 FlashLite™ does not average as many measurements. When in this mode
the Meancount/Averaged measurements value are not used. But if there is an application
where the user needs the H-3531 FlashLite™ to measure that fast this mode does work.
Therefore, the user may lose some accuracy using this mode because the H-3531
FlashLite™ is calibrated in the normal mode with the atmospheric pressure and
temperature measured every measurement. After pressing the F key the screen will
refresh with the option changed.
4.4.3 N - NOAA Mode
This options is the enable for putting the H-3531 FlashLite™ in NOAA Mode. NOAA
