eading Barometric Pressure Differential Pointer
Pressure differential is indicated in the
range of ±10 hPa (0.3 inHg), in 1 hPa (0.03
inHg) units.
•
The nearby screen shot, for example,
shows what the second hand would
indicate when the calculated pressure
differential is approximately – 5 hPa
(approximately – 0.15 inHg).
•
The second hand will point to
+ OVER
or
– UNDER
if the barometric pressure
differential is outside the allowable range
of the scale.
•
The second hand will move to 9 o’clock
if a sensor reading could not be taken
for some reason or if the reading is
outside the allowable range.
•
Barometric pressure is calculated and
displayed using hPa as the standard.
The barometric pressure differential also
can be read in inHg units as shown in
the illustration (1 hPa
=
0.03 inHg
