Power Probe PP3 Benutzerhandbuch Seite 11

An APPLICATION for the use of the "Negative Peak Mode": Lets say you
have a circuit that is suspect of loosing a connection and the voltage
drops, causing something to turn off or malfunction. Probing the circuit and
monitoring it in "Negative Peak Mode" will instantly indicate as the circuit
drops in vo tage You can monitor the circuit while wiggling wires and
pulling on connectors to see if the voltage drops. Since the minimum
voltage reading is captured and held on the display, you can inspect it at a
later time You could also perform a battery crank test
Mode #3 Positive Peak
The "Positive Peak Mode", monitors the probed circuit and captures the
highest detected voltage. Place the PP3 into "Positive Peak Mode" by
pressing and holding the mode button for 1 second until you hear a beep
Repeat this until you hear a quick high pitched beep and the LCD display
indicates a positive (plus) sign in the lower left corner. The display should
also indicate a reading of "0.0" with the probe tip floating. Probe the circuit
and the PP3 instantly displays and holds the highest voltage reading This
means you can remove the probe away from the circuit and the vo tage
reading remains displayed for your reference. Reset the LCD display by
doing a quick tap of the mode button
An APPLICATION for the use of the 'Positive Peak Mode": Let's say you
have a circuit that is supposed to be off and is suspected of turning on
inappropriately or getting a signal for some reason. Probing the circuit and
monitoring it in the"positive peak mode" wil instantly indicate as the circuit
increases in voltage. You can monitor the circuit while wiggling wires and
pulling on connectors to see if the voltage increases Since the maximum
voltage reading is captured and held on the display, you can inspect the
reading at a later time.
Maybe you have to probe a circuit deep under a dash and the display is
obstructed from view In "Positive Peak Mode" just probe the wire then
remove the probe and look at your voltage reading. Connect to starter
terminal to capture maximum voltage to the starter while cranking. Quickly
finds voltage drops in the wiring & start connection (So enoid)
Mode #4 Peak to Peak
The Peak to Peak Mode measures the difference between the positive and
negative peak voltage levels over a 1 second period. With this feature
you can measure and monitor for example, the diode rectifier in a
charging system while the engine is running The peak to peak readings
will give the technician the data necessary to determine if a diode rectifier
is defective or not. A normal peak to peak reading while testing a
charging circuit is usually under a volt. If a defective rectifier is present
the peak to peak reading will be over 1 volt and possibly over 3 volts
When probing in "Peak to Peak Mode" the display shows activity of circuits
such as fuel injectors, distributor pick-ups,cam
oxygen sensors, wheel speed sensors, hall effect sensors
back voltage of injectors to quickly find a problem
