Power Probe IV

Testing and Measuring Operations

Activating Components in VDC Mode

Activating Electrical Components in VDC Mode is one of the main features

that make the Power Probe IV very useful when testing. Being able to ap-

ply battery power or ground right to the probe tip gives you the ability to

activate and dynamically test electrical components such as lights, motors,

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 component being

tested draws too much current, or the circuit has a shorted condition, the

Power Probe IV's circuit breaker will trip protecting the tool and the circuit.

When the circuit

breaker is tripped, the

PPIV display will show

"CIRCUIT BREAKER

RESETTING" and

will automatically

reset itself after a few

seconds.

Pressing the rocker switch in any

other mode will not apply power

or ground and the main screen

will display a large red "X".
