ACTIVATING COMPONENTS IN VDC MODE
Activating Electrical Components in VDC Mode is one of the
main features that makes the
Maestro

very useful in test-
ing. Being able to apply battery power or ground right to the
probe tip gives you the ability to activate and
dynamically test electrical components such as lights, mo-
tors, and solenoids.
You can power up components on the vehicle or on the
bench by utilizing the auxiliary ground lead. This type of
dynamic component testing is the only true method to
verify a components correct operation. Testing a part with
a volt-ohmmeter may tell you if the part is out of spec, but
you never really know if the part is good until it is operating
under power.
Pressing the rocker switch forward supplies battery power to
the probe tip.
Pressing the rocker switch rearward supplies battery ground
to the probe tip.
The power output is circuit breaker protected. If the compo-
nent being tested draws too much current, or the circuit has
a shorted condition, the
Maestro
™
circuit breaker will trip
protecting the tool and the circuit.
Pressing the rocker
switch in any other
mode will not apply
power or ground and
the main screen will
