Safety Summary
Specific Precautions
xvi
Observe
all
of the following precautions to ensure your personal safety and
to prevent damage to either the
TAS
475 and
TAS
485 Analog Oscilloscopes
or equipment connected to them.
Do Not Perform Service While Alone
Do
not perform internal service or adjustment of this product unless another
person capable of rendering first aid and resuscitation
is
present.
Use Care When Servicing With Power On
Dangerous voltages exist at several points
in
this product.
To
avoid personal
injury, do not touch exposed connections or components while power
is
on.
Disconnect power before removing protective panels, soldering, or replacing
components.
Power Source
The
TAS
475 and TAS 485 Analog Oscilloscopes are intended to operate
from a power source that
will not apply more than 250 VRMS between the
supply conductors or between either supply conductor and ground. A pro-
tective ground connection, through the grounding conductor
in
the power
cord,
is
essential for safe system operation.
Grounding the Oscilloscope
The
TAS
475 and
TAS
485 Analog Oscilloscopes are grounded through the
power cord.
To
avoid electric shock, plug the power cord into a properly
wired receptacle where earth ground has been verified by a
qualified service
person. Do this before making connections to the input or output terminals of
the oscilloscope.
Without the protective ground connection,
all parts of the
TAS
475 and
TAS
485 Analog Oscilloscopes are potential shock hazards. This includes
knobs and controls that may appear to be insulators.
Use the Proper Power Cord
Use only the power cord and connector specified for your product. Use only
a power cord that is in good condition.
Use the Proper Fuse
To
avoid fire hazard, use only the fuse specified
in
the parts list for your
product.
It must be identical
in
type, voltage rating, and current rating.
