Circuit Breaker

Voltage & Polarity Testing

In Voltmeter Mode (Mode #1) with the circuit breaker tripped, the display will show “Circuit Breaker

Tripped”(see page 11-12 for detail) All other functions of the PP3S are still active. This means that you

can still probe a circuit and observe the voltage reading. When the circuit breaker is tripped, the PP3S

will NOT be able to conduct battery current to the tip even when the power switch is pressed. Intention-

ally tripping the breaker and using the PP3S to probe can be considered an added precaution against

accidental pressing of the power switch.

While the PP3S is in Voltmeter 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 PP3S is in Voltmeter 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.

While the PP3S 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.

While the PP3S is in Power Probe Mode. Contact the probe

tip to a

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.
