Safety Instruction
The following general safety precautions must be observed during all phases of operation,
service, and repair of this instrument. Failure to comply with these precautions or specific
WARNINGS given elsewhere in this manual will violate safety standards of design,
manufacture, and intended use of the instrument. The company take no liability for the
customer’s failure to comply with these requirements.
BEFORE APPLYING POWER
Verify that the power is set to match the requirement of product design.
PROTECTIVE GROUNDING
Make sure to connect the protective grounding to prevent an electric shock before turning on
the power.
NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding wire, or disconnect the wiring of
protective grounding terminal. Doing so will cause a potential shock hazard that may bring
injury to a person.
FUSE
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. Warning: Make sure to unplug the power cord before
replacing the fuse.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT REMOVE THE COVER OF THE INSTRUMENT

Operating personnel must not remove the cover of the instrument. Only qualified service
personnel can perform component replacement and internal adjustment.

Safety Symbols
DANGER -High Voltage
Explanation:To avoid injury, death of personnel, or damage to the
instrument, the operator must refer to an explanation in the instruction
manual.
Protective grounding terminal:This symbol indicates that the terminal must
be connected to ground before operation of equipment.
CAUTION
The CAUTION sign denotes a hazard. It calls attention to a procedure,
practice, or the like, which, if not correctly performed or adhered to, could
result in personal injury. Do not proceed beyond a CAUTION sign until the
indicated conditions are fully understood and met.
