Checking for
bad ground
contacts
(To avoid burning out the component, please refer to the specifica-
tion and parameter of component and then set the OVERLOAD
CURRENT VALUE )
If the probe circuit breaker tripped, it means the probe is overload-
ed. This could happened by the following reasons:
● You have connected the probe tip to the direct ground or nega-
tive voltage.
●
The component you are testing is short circuited.
●
The component is a very high current component. (such as
STARTER MOTOR)
NOTE:
If you are contacting a protected circuit, the vehicle fuse can be
burn-out or probe tripped if you apply ground to it.
Use the probe tip to find the suspected ground wire.
●
Enter into component activation interface. Select MOMENT
mode function, set the overload current to 1A.
●
Connect probe tip to a suspected wire.
