or deeth due lo shock,
the third wire earth ground must
be
con-
tinuous to the facility power outlet.
Before connecting to the facility power
outlet, examine extension cords, auto-
transformers,
etc., between
the Instru-
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;
ol
the three terminals, the earth ground
terminal Is the nonmalching shape,
usually cylindrical.
CAUTION
To prevent damage to the
instrument,
check for
proper match
of
line and instru-
ment voltage and proper fuse
type
and
rating
NOTE
Unless otherwise specified
at
the time ot
purchase, this instrument was shipped
from the factory for operation on a 90 to
128
Vac
line supply
and with a
