14.6 MEASUREMENT ON THE HV COIL – SECONDARY WINDING (SINCE SW VERSION – 11.0)
The measuring is carried out by means of HV sensors that are connected to HV cables or to the ignition module.
Types of high-voltage sensor and their use in oscilloscope – see Chap. I - 14.6.1 and Chap. I - 14.6.4
14.6.1 HV SENSOR N (AT111 4018) + HV REFERENCE CABLE (AT 111 4056)
Option for Multi-Diag Scope
HV probe N is used for measuring of the high voltage on the spark
plugs by fitting the vehicle HV cable – see Fig. 101.
During measuring on HV cables, when is required measuring of
flashover voltage, is necessary insert the High-voltage reference
cable between ignition cable and spark plug. At this HV Reference
cable then put HV probe N – see Fig. 102
