Mode #4 Min Peak Mode
: The Min Peak Mode monitors a positive circuit and displays the lowest voltage that it has
dropped to. To do this: Place the PP3S into Min Peak Mode by selecting MIN PEAK from the menu. The display will
show 00.0 volts if the probe tip is not connected to any voltage. Probe the positive circuit you want to test and press
the left button to reset the voltage reading. The LCD display will show the lowest detected voltage of the circuit. If
the circuit drops in voltage anytime, a new lowest reading will be captured and displayed. You can continue to reset
the voltage display by pressing the left button as often as necessary.
An APPLICATION for the use of the Min Peak Mode: Lets say you have a circuit that is suspect of losing a connection
and the voltage drops, causing something to turn off or malfunction. Probing the circuit and monitoring it in Min
Peak Mode will instantly indicate as the circuit drops in voltage. 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 load test by monitoring the vehicle’s
lowest battery voltage while cranking the starter.
Mode #5 AC Threshold Level Setting for the Peak to Peak Detection in Voltmeter Mode” (Mode #1)
This mode is
only used to adjust the threshold voltage in “Voltmeter Mode” for Peak to Peak Detection and Signal Monitoring.
To set the threshold level for the peak to peak detection in “Voltmeter Mode”, press right menu button to bring up
the menu selections, then use the left button to highlight “AC THRESHOLD”, then press the right button again to
display the AC Threshold voltage setting. The peak to peak threshold voltage settings loop incrementally from 50.0
to 0.2, to 0.5, to 1.0, to 2.0, to 5.0, to 10.0, and return back to 50.0 again. An audio installer would find the 0.2v
setting convenient. Once you select the desired threshold voltage, press and hold the right menu button again to
return to Voltmeter Mode (Mode #1). This AC Threshold setting determines the amount of AC voltage required to
automatically switch to Peak to Peak Mode and activate the speaker to allow audible monitoring of the AC signal.
