TESTING THE UNIT AND THE CONNECTIONS FIG.1
4.2.1.
Press the front part ( “ - “ ) of the rock switch, the test indicator should light RED.
4.2.2.
Press the rear part ( “= “ ), the test indicator should light GREEN.
4.2.3.
The unit is now ready for use.
4.2.4.
If the test indicator did not light, the cause may be that the battery clip connections are not good or the unit is damaged.
4.3.
WORKLIGHTS FIG.2
4.3.1.
To turn on/ off worklights, connect the clip of the auxiliary ground lead to the TOUCH contact and keep them in contact with
each other for about 0.5 second and then remove the clip from the TOUCH contact.
4.4.
POLARITY TEST FIG.3
Contacting the probe’s tip to a positive (+ ) circuit will light the test indicator RED. Contacting the probe’s tip to a negative(-)
circuit will light the test indicator GREEN. Contacting the probe’s tip to an open circuit does not turn on the test indicator.
4.5.
CONTINUITY TEST FIG.4
Note:
DO NOT
press the rock switch.
4.5.1.
By using the probe tip together with the auxiliary ground lead, continuity can be tested on wires and components which are
disconnected from the vehicle’s electrical system.
4.5.2.
When continuity is present, the test indicator will light GREEN.
4.6.
ACTIVATING COMPONENTS OUT OF THE VEHICLE’S ELECTRICAL SYSTEM FIG.5
4.6.1.
By using the probe tip together with the auxiliary ground lead, components can be activated, thereby testing their function.
4.6.2.
Connect the auxiliary ground lead’s 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 light GREEN indicating continuity through the component.
4.6.3.
Whilst watching the green test indicator, quickly press and release the rock switch’s front part (“ - “). If the green test indicator
changed instantly from GREEN to RED, you may proceed with further activation. If the green test indicator went
off at that instant, the unit has been overloaded. This could happen for the following reasons:
a. The contact of the tip is a direct ground or negative voltage.
b. The component is short-circuited.
c. The component is a high amperage component ( i.e. starter motor).
