Safety Tips for Handling Electronic Measurement Devices
Protective Lead
Connection The protective lead should be attached to the protective lead connector before
any other connection is made.
Risks of a
Disconnected
Protective Lead The analyzer system can be hazardous if the protective lead is interrupted inside
or outside the system or if the protective lead is disconnected.
Correct Operating
Voltage Be sure the analyzer system voltage setting matches the line voltage before
connecting the power supply.
Risks Involved in
Opening the Covers Current-bearing components can be exposed when covers or parts are removed,
even if this can be done without tools. Current can be present at some connection
points.
Risks Involved in
Working with an
Open Analyzer
System The analyzer system must be disconnected from all power sources before being
opened for any work. All work on an analyzer system that is open and connected
to power should only be performed by trained personnel who are familiar with the
risks involved.
Charged Capacitors The capacitors in the analyzer system can retain their charge even when it is
disconnected from all power sources.
Use of Proper Fuses Only fuses of the specified type and rated current should be used as replace-
ments. Never use patched fuses. Do not short-circuit the fuse holder contacts.
When safe operation
can no longer be
assured … If it is apparent that safe operation is no longer possible, the analyzer system
should be taken out of operation and secured against unauthorized use.
The possibility of safe operation is excluded:

If the analyzer system is visibly damaged

If the analyzer system no longer operates

after prolonged storage under adverse conditions

after severe transport stresses
