WARNING
To preclude injury or death due to shock,
the third wire earth ground must be eon-
tinuous to the facility power outlet.
Before connecting to the facility power
outlet, examine extension cords, auto-
transformers, etc., between the lnstru-
ment and the facility power outlet for a
continuous earth ground path. The earth
ground path can be identified at the .
plug on the instrument power cord; of
the three terminals, the earth ground
terminal is the nonmatching shape,
usually cylindrical.
