ABSTRACT:
A test tool for a reactor vessel level instrumentation system which simulates and verifies the values of input signals applied to the instrumentation system. The test tool includes potentiometers for simulating the signals produced by resistance temperature detectors, switches for simulating pump status and isolator overrange limit signals, a power supply, resistors and potentiometers for simulating temperature hot sensors and a pressure wide range sensor, and potentiometers and resistors for simulating differential pressure cell signals. The invention also includes a switchable meter for verifying the values of the various input signals simulated.
