8. OPERATING INSTRUCTIONS
8.4 AUTO CIRCUIT BREAKER - FIG. 2
The tool is short-circuiting 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 Fig.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.
8.5 WORK MODE
There are four modes to diagnose the electrical systems, which can be accessed by depressing
the Mode Button and cycling through each one.
8.6 DC VOLTAGE - FIGS. 3 - 4
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the DC
voltage with a resolution of 0.1 volt.
