This server normally handles only one PCT device.
The device can have 3 states:
- Calibration: During this state, which last several seconds the server thread commands
the Electronics to inject calibration current. The sever calculates the gain and offsets,
which will be applied for the 2 measurement modes below.
- Injection: When the server detects an increase in the current value, it switches in
injection mode. The Voltmetere resolution is decreased in order to have faster measures.
Whne server detect that the current is stable or starts to decrease it switches back to
Lifetime mode.
- Lifetime: During the current decay, the lifetime is calculated.
