  • Diagnostic electrode for evaluating circuitry of an analyzer
    Patent number: 5344544
    Abstract: A diagnostic electrode actively generates test signals to be supplied to analyzer circuitry. The electrode emulates a disposable sensor associated with the analyzer during a normal mode of normal operation. The diagnostic device generates predetermined signals for an output interface of the device using a power supply disposed within the device. The diagnostic module can be designed to produce voltage signals, current signals, or light signals to be received by the analyzer, depending on the type of analyzer to which the diagnostic electrode is to be associated.
