WARNING
An open INTERLOCK only disables the output from the Model
622x. If an external source is being used in the test circuit, its
voltage will be present in the test circuit. A hazardous voltage
from an external source could be connected directly to the
OUTPUT connector of the Model 622x.
As a general rule of safety, always turn off all external sources
before making or breaking connections to the test circuit.
