Safety Summary
Ground the Instrument
To minimize shock hazard, the instrument chassis and cover must be
connected to an electrical protective earth ground. The instrument must
be connected to the ac power mains through a grounded power cable,
with the ground wire firmly connected to an electrical ground (safety
ground) at the power outlet. Any interruption of the protective
(grounding) conductor or disconnection of the protective earth terminal
will cause a potential shock hazard that could result in personal injury.
Fuses
Only fuses with the required rated current, voltage, and specified type
(normal blow, time delay, etc.) should be used. Do not use repaired fuses
or short-circuited fuse holders. To do so could cause a shock or fire
hazard.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases or
fumes.
Do Not Remove the Instrument Cover
Operating personnel must not remove instrument covers. Component
replacement and internal adjustments must be made only by qualified
service personnel.
Instruments that appear damaged or defective should be made
inoperative and secured against unintended operation until they can be
repaired by qualified service personnel.
