Activating Components In Your Hand
While the PP3S is in Voltmeter Mode and by using the Power Probe tip in connection with the auxiliary
ground lead, components can be activated right in your hand, thereby testing their function. Connect the
negative auxiliary clip to the negative terminal or ground side of the component being tested. Contact
the probe to the positive terminal of the component, the
green negative
sign “-“ LED indicator should
light
GREEN
indicating continuity through the component.
While keeping an eye on the green LED negative sign, quickly depress and release the power switch
forward (+). If the green negative sign “-“ LED went out and the red positive sign “+” came on, you
may proceed with further activation. If the
green negative
sign “-“ LED went off at that instant or
if the circuit breaker tripped, the Power Probe has been overloaded. This could happen for the following
reasons:
• The contact you are probing is a direct ground or negative voltage.
• The component you are testing is short-circuited.
• The component is a very high current component (i.e., starter motor).
If the circuit breaker is tripped, reset it by waiting for it to cool down (15 sec.) and then depressing the
reset button.
