Abstract (en)
[origin: EP1054154A2] The arrangement has a measurement voltage generator (1) connected to an ignition current bypass (2) and a measurement signal converter (4) connected to the measurement voltage generator and bypass. The current to voltage converter has an operational amplifier with negative input connected to the measurement voltage generator, ignition current bypass and, via a resistance, to output. Its positive input is connected a slightly higher potential (earth).
