Not Measurable

Check the test leads for continuity (short-circuit them to test).

Current Cannot Be Measured

The fuse may be blown. Replace the fuse as described in the Maintenance section.

Penggantian Baterai

When the LCD displays a red battery icon, the battery should be replaced. The device uses 3 AA 1.5V batteries.
