The System Test Kit uses the method of low voltage injection to perform its tests. The test kit
drives these low level voltages (10V p-p) into individual test inputs of the Messenger's A/D
converter. Basic protection scheme, Functional protection, and Single Point Relay protection of
the entire system can be tested using low voltage injection from the System Test Kit.
