FIELD: transport.
SUBSTANCE: device incorporates recorder (1), controlled gain amplifier (3), threshold element (7), signaling unit (8), mode selector switch, voltage divider (4), two operational amplifiers (15, 16) and three rail contacts. The said device comprises also the second controlled gain amplifier (6), two parameter selector switches, two electronic switches with different operation thresholds (22, 23), resistance bank (21), adder (20) and subtractor (19), the fourth rail contact to be connected, given the current asymmetry measurement, to the first terminal of the second operational amplifier input, not to the second rail contact.
EFFECT: expanded performances.
