The thermovoltage value then sinks to a certain basic level that is specific to the
engine, and depends on its load and operating time. The BCom Evaluator monitors
all changes that occur during the engine operation and triggers an alarm should
these changes indicate danger.

The effect of high voltage peaks also occurs when the engine is being shut down.
Some thermovoltage level can be measured even some time after engine stop,
until the temperatures at contact spots level out.
