While the PP3 is in Power Probe Mode, contact the probe tip to a POSITIVE circuit. The red positive sign “+”
LED will light and the voltmeter displays the voltage with a resolution of 1/10th of a volt (0.1v).
If the audio feature is turned on, a high pitched tone will sound.

While the PP3 is in Power Probe Mode, contact the probe tip to a NEGATIVE circuit. The green negative
sign “–” LED will light and the voltmeter displays the voltage. If the audio feature is turned on, a low pitched
tone will sound.
Contacting the Power Probe tip to an OPEN circuit will be indicated by neither of the LED indicators lighting.
In Power Probe Mode (Mode #1) with a the circuit breaker tripped, the LCD will display the symbol “C B”.
(see page 11-12 for detail) All other functions of the PP3 are still active. This means that you can still probe a
circuit and observe the voltage reading. When the circuit breaker is tripped, the PP3 will NOT be able to con-
duct battery current to the tip even when the power switch is pressed. Intentionally tripping the breaker and us-
ing the PP3 to probe can be considered an added precaution against accidental pressing of the power switch.
