General Tools and Instruments BF10 - Manual (Page 4)

The plug-in transmitter also doubles as a socket tester. By
measuring leakage currents, it can identify five common
outlet wiring faults: missing earth (ground), missing neutral,
live and earth reversed, live and neutral reversed, and open
circuit. The type of fault is indicated by a unique pattern of
colored LEDs on the front of the transmitter as well as the
pulsed tone that it emits.
The BF10 is NOT a comprehensive diagnostic instrument:
• It cannot test the ground fault circuit interruption function of
GFCI receptacles.
• It cannot measure the quality of earth (ground) connections,
detect two hot wires or more than one fault in a circuit, or
detect reversed grounded and grounding conductors.
The BF10 is a simple instrument for detecting common
improper wiring of GFCI and non-GFCI outlets. All detected
problems should be referred to a qualified electrician.
If you need a comprehensive diagnostic instrument, General
recommends its CA10 Circuit Analyzer. For details, visit
