ABSTRACT:
The present invention is directed to a method and apparatus for testing the operation of a sensor controlled monitor device by using a test device connected in parallel to the monitor device. When activated, the test device sinks a current signal, representing a parameter to be monitored, in a steadily changing, calibrated manner, causing an input to the monitor device to vary, thus permitting the monitor device to respond to the varied signal to calibrate or test alarm settings and function. The present invention permits easy confirmation of the monitor device's gain adjustment, zero adjustment, and setpoint adjustment. In addition, there is no need to physically disconnect the transmitting sensor circuit or to physically change the amount of the substance being monitored. There is also no need to disturb any wiring of existing circuits.
