详细的Mars5 微波消解手册（英文）
The MARS 5 must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an escape wire for electric current.
This instrument is equipped with a cord having a grounding wire with a grounding
plug. The plug must be plugged into an outlet that is properly installed and
grounded. Consult a qualified electrician or service technician if the grounding
instructions are not completely understood or if doubt exists as to whether the instrument
is properly grounded. If it is necessary to use an extension cord, use only a 3-
wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that
will accept the plug from the instrument. The marked rating of the extension cord
must be equal to or greater than the electrical rating of the instrument.
The possibility of instrument-induced electromagnetic interference (EMI) is minimal
if the instrument is operated as outlined in this manual. The instrument should not
be placed close to any electrical device susceptible to EMI. It is suggested by the
manufacturer that the user post a sign warning pacemaker wearers that a microwave
device is in operation. If the instrument is suspected of inducing EMI, a microwave
leakage measurement should be performed as outlined on page 61. Leakage
measured above the legal limit of 5 mW/cm2 should be reported to the CEM Service
Department.
Cardiac pacemakers require magnets to control their operation during checkout. If
the instrument is equipped with an optional magnetic sample stirrer which contains
very high static magnetic fields, some danger exists if a pacemaker is positioned in
close proximity of the instrument cavity (such as placing the head into the instrument
cavity to perform a visual inspection). If the instrument is suspected of interferring
with the operation of a pacemaker, the instrument should be turned off or the
pacemaker wearer should move away from the instrument.
This instrument utilizes high voltages and microwave radiation. Instrument service and
repair should be performed only by those trained in repair and maintenance of high
voltage and microwave power systems.
Warnings, cautions and notes are included throughout this manual and should be
read thoroughly and strictly followed.
WARNING: A warning is inserted for essential information used to emphasize
dangerous or hazardous conditions to the operation, cleaning and maintenance of the
instrument which may result in personal injury.
CAUTION: A caution is inserted for essential information used to emphasize
procedures which, if not strictly followed, may result in damage or destruction to the
instrument or improper instrument operation.
NOTE: A note is inserted for emphasis of procedures or conditions which may otherwise
be misinterpreted or overlooked and to clarify possible confusing situations.
This instrument complies with United States Code of Federal Regulations (CFR)
Title 21, Part 1030 for microwave leakage. A verification report is on file.
This instrument complies with United States Code of Federal Regulations (CFR)
Title 47, Federal Communications Commission (FCC) Part 18 – Industrial, Scientific
and Medical (ISM) Equipment – emissions requirements. A verification report is on
file.
