2.7 Circuit Breaker
The tool is short-circuit protected. Its internal circuit breaker will trip
if it becomes overloaded. The circuit breaker is a valuable test tool as
well as a safety measure to protect the tool from overload.
When circuit breaker tripped, the LCD will display as below. (Figure
2) All other functions of the tool are still active, which means you
can still probe a circuit and observe the voltage reading. When the
circuit breaker is tripped, the tool will NOT be able to conduct
battery current to the tip even when the power switch is pressed.
Intentionally tripping the breaker and using the tool to probe can be
considered an added precaution against accidental pressing of the
power switch.
