Abstract:
1. A testing device for determining values of various electrical properties associated with a device within a process system, comprising: a set of ports to provide an electrical interface; a processing unit; and a port control circuitry, operatively connected to said set of ports and said processing unit, to automatically provide a connection configuration between said processing unit and said set of ports, said connection configuration governing a flow of electrical signals between said processing unit and the device to be monitored; said processing unit outputting an analog test signal and a configuration control signal to said port control circuitry; said port control circuitry, in response to the analog test signal and configuration control signal, automatically providing a connection configuration to direct the analog test signal to the device to be monitored and to direct an analog return signal associated with a first port of said set of ports, said analog return signal associated with the first port of said set of ports being generated by the monitored device in response to the analog test signal, to said processing unit; said processing unit, based upon the connection configuration of said port control circuitry, measuring an electrical property of said analog return signal associated with the first port of said set of ports and determining two properties associated with the monitored device based upon the measured electrical property of said analog return signal associated with the first port of said set of ports generated by the monitored device.
