The size of the measurement error depends on the
ignition cable insulation and applies to use in vehicle
systems with mechanical distributors. The kV input and
the kV pick-up (ignition voltage adapter) form a capaci-
tive voltage divider. The tester can be adapted to a sta-
tionary ignition distributor system by external
connection of the ignition voltage adapter.
Trigger pick-up input
To record ignition timing on high-voltage cables
(secondary ignition coil)
