While the PP3 is in Power Probe Mode. Contact the probe

tip to a

NEGATIVE circuit. The green negative sign “-

” LED will light. If the audio feature is turned on, a low

pitched tone will sound.

VOLTAGE & POLARITY TESTING (PPM)

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. (See RED/GREEN POLARITY INDICATOR

& AUDIO TONE on page 10)

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.

CIRCUIT BREAKER

While the PP3 is in Power Probe Mode, contact the probe tip to

POSITIVE circuit. The red positive sign “+” LED will light

and the voltage reading of the circuit will be indicated on the

LCD display. If the audio feature is turned on, a high pitched

tone will sound.
