MoTeC Overview 9
The comparison values can be automatically incremented or (decremented)
when an alarm occurs. For example the engine temperature alarm may be set
at 95
°C with and increment of 5°C, so that the second time the alarm
activates it activates at 100 °C. A limit may be set on the number of times the
comparison value is allowed to increment, also it may return to its original
value after a period of time, in case the alarm condition was temporary.
The alarms can also be dependent on the current display mode (Race,
Practice or Warmup)
Data Logging
Data logging allows the sensor readings (or any calculated value) to be stored
in the ADL2 for later analysis on a Personal Computer.
Logging Memory
The ADL2 comes with 16Mbytes of memory with 8Mbytes enabled as
standard. The full 16Mbytes can be enabled by purchasing the 16Mbyte
option.
Power
The ADL2 power can be turned off at any time without losing the logged data.
The ADL2 uses FLASH memory which does not require an internal battery to
keep it alive.
Logging Rate
The ADL2 can store any value at up to 1000 times per second, which can be
individually set for each logged item.
The rate at which the values are logged is very important – the value must be
logged fast enough to record all variations in the reading. If the value is
logged too slowly then the readings can be totally meaningless. For example
suspension position normally needs to be logged at 100 times per second or
more.
Note, however, that if a value is logged faster than necessary it will not
improve the accuracy of the logged data, it will just reduce the total logging
time available. For example, the engine temperature only needs to be logged
at once per second.
