Description How events registered
1 Switcher sensors:
engine operation;
digital;
engine efficiency;
private mode;
alarm trigger;
counter(switch to ON/to OFF)
Events are registered from ON position
to OFF position.
2 Instant sensors:
odometer;
relative engine hours;
instant fuel consumption;
counter(instant)
Events are registered from the first non-
zero value to the last non-zero one.
3 Differential sensors : mileage;
engine hours;
impulse fuel consumption;
absolute fuel consumption;
counter(differential + with overflow);
fuel level impulse sensor
Events are registered from start of value
increasing to the end of it.
4 Analog sensors: temperature;
engine rpm;
voltage;
weight sensor;
accelerometer;
temperature coefficient;
custom
Events are not registered.
