If the protective fuse has blown, the unit can only be put back into operation after 60 seconds.
By then the fuse has regenerated.
IMPORTANT
Carry out the following work with great caution and follow the test schemes to avoid damage to the
components or the multitester. Use the test probe to apply positive voltage. This may be helpful in
diagnosing the component.
IMPORTANT
When applying current to a component, press the switch of the multitester before touching the com-
ponent with the test probe. In such a case, arcing occurs between the test probe and the component
and not at the switch. In this way you increase the durability of the switch.

During a test, the unit can be used to apply negative voltage to the component.
To do this, follow the steps below:
3.
Touch the test probe to the negative pole of the component. If the RED LED lights up,
the component is working properly.
4.
Now move the polarity switch backwards and release it again directly. If the LED now changes
from RED to GREEN, continue with the test. If the GREEN LED does not light up, the multitester is
probably overloaded or the protective fuse has blown.
