5.2. Continuity Testing
5.2.1. While the probe is in resistance mode, continuity can be tested on wires and components attached to or disconnected from the
vehicle’s electrical system by utilizing the probe tip when connected with a chassis earth or the auxiliary earth lead (g.9).
5.2.2. Where continuity is present the LCD screen will display ‘0.0Ω’ and the green LED will illuminate. If the audible indicator is turned on a
low pitched tone will emit.
5.2.3. In any other instance the LCD screen will display the resistance value (g.10). For any resistance value greater than 199kΩ the LCD
screen will display ‘OL’.
5.2.4. Another method to check for continuity of connections to earth or the battery is to use the power switch. If the circuit breaker trips,
there is a good, low-resistance connection.

5.3. Signal Circuit Testing
5.3.1. The tool can be used as a trouble shooting aid to test sensors/components in a circuit where a DTC (Diagnostic Trouble Code) has
been detected during an on-board diagnostic scan.
5.3.2. Always refer to the vehicle manufacturer’s service instructions, or a proprietary manual to establish the current procedure and data for
testing and location of the sensor/component to be tested.
5.3.3. Set the tool to scope mode and attach the auxiliary ground lead to earth. Use the probe tip on the terminals of the sensor/component
as described in the manufacturer’s test procedures and observe the signal and readings on the LCD display screen (g.11).
5.3.4. Any abnormal signals or readings may indicate a fault with the sensor/component.
5.4. Activating Components Removed From Vehicle Electrical System (Such as fuel pumps, starter solenoids, magnetic clutches,
blowermotors,coolingfans,lightsetc.)
5.4.1. By using the probe tip together with the auxiliary earth lead, components can be activated, thereby testing their function.
5.4.2. Set the tool to the voltage mode.
5.4.3. Connect the auxiliary earth lead clip to the negative terminal of the component to be tested. Contact the probe to the positive terminal
of the component. The test indicator should illuminate green, indicating continuity through the component (g.12).
5.4.4. Quickly press the power switch forward to the positive position and release. If the test indicator changes from green to red, you may
proceed with further activation. Press and hold the power switch forward to energise the component being tested.
5.4.5. If circuit breaker activates, the unit has been overloaded. The maximum current rating is 8Amps. This could happen for the following
reasons:
a) Where the tip of the tester has made contact is a direct earth or a negative voltage.
b) The component has a short circuit.
c) The component requires a high current (e.g. a starter motor).
Note: The tool is equipped with a built in circuit breaker for overload protection. Should the circuit breaker be activated, reset using the
circuit breaker reset (g.1 item 5).
5.5. Testing Trailer Lights and Connections
5.5.1. Set the tool to the voltage mode.
5.5.2. Connect to a battery of the correct voltage for the trailer electrical
system (g.13).
5.5.3. Clip the auxiliary earth lead to an earth on the trailer chassis.
5.5.4. Probe the contacts of the trailer’s electrical connection socket
whilst pressing the power switch forward to the positive position.
5.5.5. This will allow you to check the function and orientation of the
trailer lighting system.

5.6. Activating Components With a Positive(+)Voltage Within Vehicle Electrical System
5.6.1. Set up the tool as shown in g.14 and set to voltage mode.
5.6.2. Contact the probe tip to the positive terminal of the component, the test indicator should illuminate green. Whilst observing the test
indicator, quickly press and release the power switch forward to the positive position. If the indicator changes instantly from green to
red the tool is ready for use.
5.6.3. If the circuit breaker activates, the unit has been overloaded. This could happen for the following reasons:
a) The tip’s contact went to direct earth.
b) The component has a short circuit.
c) The component is a high current component (i.e. starter motor)
WARNING! Randomly applying voltage to certain circuits can cause damage to a vehicle’s electronic components. It is
strongly advised to use the correct circuit diagram and diagnostic procedures whilst performing this test.
g.14
5.7. Activatingcomponentswithanegative(-)voltagewithinvehicleelectricalsystem
5.7.1. Set up the tool as shown in g.15 and set to voltage mode.
5.7.2. Contact the probe tip to the negative terminal of the component, the test indicator should illuminate red.
5.7.3. Whilst observing the test indicator, quickly press the power switch rearwards to the negative position and release it. If the indicator
changes instantly from red to green the tool is ready for use.
5.7.4. If the circuit breaker activates, the unit has been overloaded. This could happen for the following reasons:
a) Where the tip of the tester has contacted is a direct positive voltage.
b) The component has a short circuit.
c) The component is a high current component (e.g. a starter motor) (8Ampmax.)
WARNING! With this function a vehicle’s fuses may blow when the probe tip is earthed in series with them.
5.8. Checking For Bad Earth Contacts
5.8.1. With the tool connected to the battery supply, set to the voltage mode.
5.8.2. Probe the suspected earth wire or contact with the probe tip. Observe the colour of the test indicator.
5.8.3. Press the power switch forward to the positive position and release it. If the test indicator changes from green to red, this is not a true
earth. If the circuit breaker tripped when the power switch was pressed forward, this circuit is more than likely a direct earth. Note that
high current components such as a starter motor will also cause the test indicator to trip off during this check.
5.9. Following and Locating Short Circuits
5.9.1. In most cases a short circuit will appear by a fuse or a fusible link blowing or an electrical protection device tripping (i.e. a circuit
breaker).
5.9.2. Connect the tool to the battery supply. Remove the blown fuse from the fuse box. Use the probe to activate and energise each of the
fuse contacts. The contact which trips the probe circuit breaker is the shorted circuit. Take note of this wire’s identication code or
colour.
5.9.3. Follow the wire as far as you can along the wiring harness. For instance if you are following a short in the brake light circuit you may
know that the wire must pass through the wiring harness at the door sill. Locate the colour-coded wire in the harness and expose it.
5.9.4. Probe through the insulation with the probe tip depress the power switch forward to activate and energise the wire. If the circuit
breaker tripped you have veried the shorted wire.
5.9.5. Cut the wire and energise each end with the probe. The wire end which trips the circuit breaker again is the shorted circuit and it
will lead you to the shorted area. Follow the wire in the shorted direction and repeat this process until the short is located.
5.10. Voltage Differentials
5.10.1. The red/green LED’s will only illuminate when the voltage at the probe tip is within ±0.8Volts of the supply battery voltage. This is a
useful feature for some fault nding procedures.
5.10.2. If the circuit voltage is not within ±0.8Volts of the supply battery voltage, the LCD screen will display the voltage gure at the circuit but
no LED’s will illuminate. This will indicate a difference of ±0.8Volts between the supply battery voltage and the voltage in the circuit
being tested. Remove the probe tip from the circuit and press the power switch forward. The LCD screen will now display the
-supply battery voltage. The difference between the supply battery voltage and the circuit voltage can now be determined.
5.11. Using With Sensitive Circuits
5.11.1. The LED’s and the LCD screen draw no more than 1mA current ensuring that the tool is safe for use as a multimeter or test light on
sensitive ECU controlled electronic circuits such as the airbag circuit.
