(4) Read the data monitor.
Criteria
: Almost equal to atmospheric pressure
NOTE:
·Standard atmospheric pressure is 101 kPa {758 mmHg, 29.8 inHg, 14.6 psig}.
·Atmospheric pressure decreases by 1 kPa {8 mmHg, 0.3 inHg, 0.1 psig} as the altitude increases by 100 m {328 ft}.
·Atmospheric pressure varies according to the weather.
