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 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 bat-
tery crank test.
Mode #3 Positive Peak Mode:
The "Positive Peak Mode", monitors the probed circuit
and captures the highest detected voltage. Place the
HC-CARGO 211097 into "Positive peak Mode" by pres-
sing and holding the mode button for 1 second until you
hear a beep. Repeat this until you hear a quick high pit-
ched beep and the LCD display indicates a positive (+)
sign in the lower left corner. The display should also indi-
cate a reading of "0.0" with the probe tip floating. Probe
the circuit and the HC-CARGO 211097 instantly displays
and holds the highest voltage reading. This means you
can remove the probe from the circuit and the voltage
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": Lets say you have a circuit that is supposed to
be off and it is suspected of turning on inappropriately or
getting a signal for some reason. Probing the circuit and
monitoring it in the "Positive Peak Mode" will 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 and
start connection (Soledoid).
Mode #4 Peak to Peak Mode:
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
necessarry to determine if a diode rectifier is defective
or not. A normal peak to peak reading while testing a
charging circuit is usually under 1 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, distri-
butor pick-ups, cam and crank sensors, oxygen sensors,
hall effect sensors. Measures flyback voltage of injectors
to quickly find a problem.
Mode #5 Treshold Level Setting for the Peak to Peak
Detection in Power Probe Mode:
This mode is only used to adjust the treshold voltage
in "Power Probe Mode" for peak to Peak Detection and
Signal Monitoring. To set the threshold level for the peak
to peak detection in "Power Probe Mode", press and
hold the mode button for one second until you hear the
beep. Repeat this a second, third and fourth time and/or
until an alternating positive (+) and negative (÷) sign is
present in the bottom left corner of the LCD display. You
can now toggle the threshold level by a quick tap of the
mode button and observing the voltage level settings.
The peak to peak threshold voltage settings loop
incrementally from 0.2, to 0.5 to 1.0 to 2.0 to 5.0 to 10.0
to 50.0 and return back to 0.2 again. An audio installer
would find the 0.2 V. setting convenient.
Once you select the desired threshold voltage, press
and hold the mode button again until it beeps. This
returns you to the "Power Probe Mode". You will know
that you are in the "Power Probe Mode" when the LCD
display is blank and/or with the "Speaker Symbol" shown
in the bottom right corner.
