4. OPERATION
4.1.
Basic Connections.
4.1.1.
Unroll the Probe cable. Connect the RED battery clip to the POSITIVE terminal of the vehicle's battery. Connect the BLACK battery
clip to the NEGATIVE terminal.
4.1.2.
When the probe is first connected to the battery, it will sound a quick high beep, then a low beep and then go into "Power Mode"
4.1.3.
The two LED work lights will be on to illuminate the test area of the probe.
4.2.
Quick Self Test.
4.2.1.
Press switch toward (+) to activate the probe with a POSITIVE (+) voltage. The POSITIVE sign (+) LED should light red and the LCD
display will read the battery (supply) voltage. If the tone feature is turned on, a high pitched tone will sound.
4.2.2.
Press the switch toward (-) to activate the probe with a NEGATIVE (-) voltage. The NEGATIVE sign (-) LED should light green and the
LCD display will read "0.0". If the tone feature is turned on, a low-pitched tone will sound.
4.2.3.
The probe is now ready to use.
4.3.
Voltage and Polarity Testing. See fig.2.
4.3.1.
Contact the probe tip to a POSITIVE circuit. The red positive sign, (+) LED will light and the voltmeter will display the voltage.
4.3.2.
A high-pitched tone will sound.
4.3.3.
While the PP7 is in "Power Mode", contact the probe tip to a NEGATIVE circuit. The green negative sign, (-) LED will light and the
voltmeter will display the voltage.
4.4.
Continuity Testing. See fig.3.
4.4.1.
Continuity can be tested on wires and components attached or disconnected from the vehicle's electrical system and by utilizing the
Probe tip when connected with a chassis earth or the auxiliary earth lead.
4.4.2.
The Probe indicates continuity using two resistance levels. When the Probe tip has a resistance to earth of less than 20K Ohms but
greater than 2K Ohms the LCD will indicate "0.0" volts but no green (-) LED.
4.4.3.
When the resistance to earth is less than 2K Ohms the LCD will indicate "0.0" volts and the green (-) LED will illuminate.
Contact the probe tip
to a NEGATIVE circuit.
The green negative
sign (-) LED will light,
a high pitched tone will
sound.
fig.2
4.5.
Activating Components in Your Hand. See fig.4
4.5.1.
Connect the negative auxiliary clip to the negative terminal or earth side of the component being tested.
4.5.2.
Contact the probe to the positive terminal of the component, the green negative sign (-) LED indicator should light GREEN indicating
continuity through the component.
4.5.3.
Observe the green LED indicator and quickly depress and release the switch forward (+). If the green LED indicator went out and the
red positive sign (+) came on, you may proceed with further activation.
4.6.
Testing Trailer Lights and Connections. See fig.5.
4.6.1.
Connect the Probe to a good battery.
4.6.2.
Clip the auxiliary earth clip to the trailer earth.
4.6.3.
Probe the contacts at the jack and then apply voltage to them. This lets you check the function.
