Safety Tips for Handling Electronic Measurement Devices
Protective Lead
Connection
The protective lead (ground) should be attached to the protective lead connector
before any other connection is made.
Risks of a Disconnect-
ed Protective Lead
The gas analyzer can be hazardous if the protective lead is interrupted inside or
outside the gas analyzer or if the protective lead is disconnected.
Proper Operating
Voltage
Be sure the gas analyzer voltage setting matches the line voltage before connect-
ing the power supply.
Risks Involved in
Opening the Covers
Current-bearing components can be exposed when the 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 Gas Analyzer
The gas analyzer must be disconnected from all power sources before being
opened for any work. All work on a gas analyzer 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 gas analyzer power supply discharge after 10 minutes when
the gas analyzer is disconnected from all power sources.
Use of Proper Fuses
Only fuses of the specified type and rated current should be used as replacements.
Never use patched fuses. Do not short-circuit the fuseholder contacts.
When Safe Operation
can no Longer be
Assured
If it is apparent that safe operation is no longer possible, the gas analyzer should
be taken out of operation and secured against unauthorized use.
The possibility of safe operation is excluded:
•
If the gas analyzer is visibly damaged
•
If the gas analyzer no longer operates
•
After prolonged storage under adverse conditions
•
After severe transport stresses
