OPERATING

MANUAL

SAFETY

INSTRUCTION

Carefully read through the following safety instructions before putting the

Analyzer into operation. Observe all the precautions and warnings

provided in this Manual for all the phases of operation, service, and repair

of the Analyzer.

The Analyzer must be used only by skilled and specialized staff or

thoroughly trained personnel with the required skills and knowledge of

safety precautions.

The protection provided by the equipment may be impaired if the

equipment is used in a manner not specified by the manufacturer.

A734 is tested in stand-alone condition or in combination with the

accessories supplied by GSI against the requirement of the standards

described in the Certificate of Compliance. If it is used as a system

component, compliance of related regulations and safety requirements are

to be confirmed by the builder of the system.

Never operate the Analyzer in the environment containing inflammable

gasses or fumes.

Operators must not remove the cover or part of the housing. The Analyzer

must not be repaired by the operator. Component replacement or internal

adjustment must be performed by qualified maintenance personnel only.

Never operate the Analyzer if the power cable is damaged.

Never connect the test terminals to mains.

If the equipment is used in a manner not specified by the manufacturer,

the protection provided by the equipment may be impaired.

Electrostatic discharge can damage your Analyzer when connected or

disconnected from the DUT. Static charge can build up on your body and

damage the sensitive circuits of internal components of both the Analyzer

and the DUT. To avoid damage from electric discharge, observe the
