• Standard atmospheric pressure: 101 kPa(abs) [758 mmHg(abs)].

• For every 100 m increase in altitude, pressure drops by 1 kPa (7.5 mmHg).

  Value varies with by weather (high atmospheric pressure, low atmospheric pressure).

• Outputs the alternator generation duty in order to see the electrical load.

• Can be used to determine whether a higher than normal injection volume at idle, etc. is resulting from electrical load or from some other source. For example, when the duty is not high but the idling injection volume is high, there is injector volume degradation or high engine friction.

• Can be used for judging whether or not a malfunctioning component in the electrical system is generating continual generation requests (e.g., battery deterioration is causing an unending full recharge request, etc.). Regardless of whether or not an auxiliary device like the A/C or heater is active, if the alternator duty is always at MAX status, there is an electrical system abnormality, like battery deterioration.
