Piercing wire sheath with a test probe is
forbidden.
CURRENT MEASUREMENT
General note
It is not often necessary to measure the amperage
on the engine. This requires an ammeter, which is
usually integrated in a multimeter.
ATTENTION
Amperage: Never measure the amperage in the
cable to the starter with a normal ammeter!
The measurement unit can be destroyed by the
high currents which occur here. A current
clamp can be used for measuring such high
amperages.
Procedure
Step
1 Before the current measurement, the
measurement unit is adjusted to the
measurement range in which the amper-
age you are measuring is likely to be
found. If this is not known, set the highest
measurement range, and if there is no
display, switch down to the next measure-
ment range, and so on.
2 If not using a clamp-on ammeter, the cir-
cuit must be disconnected in order to
measure the amperage. The measure-
ment unit (ammeter) is connected in
between.
