Testing and Measuring Operations
Power Feed Testing
FEED TEST
– Power Feed Test (PFT) is used to check
resistance on static circuits or voltage drops on active
circuits by simply probing one connection of the circuit
being tested.
PFT measures total circuit resistance from the source bat-
tery accurately whether there is voltage on the circuit or
not, unlike standard multimeters. With the Aux. Ground
lead, PFT can also be used like a standard ohmmeter.
PFT displays both Battery and Tip voltage simultaneously
for easy voltage drop testing.
In this mode, the Power Probe IV display will show:
- Total circuit Resistance on the center screen.
- Probe Tip Voltage.
- Battery Voltage.
The battery voltage and the tip voltage are both
displayed along the bottom of the screen for
easy voltage drop testing.
The circuit resistance will be calculated even with voltage applied to the circuit. To accurately test the
power and ground feed resistance, the component must be removed from the circuit first. Simply un-
plug any component, relay, or module on the circuit, contact the probe tip to the circuit and view the
circuit resistance.
PFT will display battery voltage (BATT V) from the battery clips in the lower left display area, probe
tip (TIP V) voltage in the lower right display area and will provide total circuit resistance readings in
the main area of the display all in one test.
