of this instruction manual.
2. Test the battery, replace as necessary.
3. Test the fuses, replace as necessary.
4. Check to see that the Function/Range Switch is in the cor-
rect position for the type of parameter and range of values
being measured, and that the measurement value is within
the capability of the multimeter.
5. Inspect the test leads for breaks or cracks, and ensure that
the test leads are inserted fully into the input connectors.
6. If problem persists, meter should be inspected by a quali-
fied service person.
