摘要: A device and method for diagnosing shorts fault conditions in electrical circuits such as heating, ventilation, air conditioning (HVAC) control circuits. The includes a positive temperature coefficient (PTC) member to protect the circuit from overcurrent during diagnosis. also light emitting diode (LED) resistor electrically connected parallel across PTC member. An condition causes resistance of rise dramatically, creating potential difference lighting LED. invention locating short an HVAC using device.
