Note

YOKOGAWA instruments have been designed in a way that the replacement of electronic

parts can be done on an assembly (module) basis by the user. YOKOGAWA instruments

have also been designed in a way that troubleshooting and replacement of any faulty

assembly can be done easily and quickly. Therefore, YOKOGAWA strongly recommends

replacing the entire assembly over replacing parts or components within the assembly. The

reasons are as follows:

• The instruments use high-performance microprocessors, large scale CMOS gate arrays,

and surface-mount components to provide state-of-the-art performance and functions.

• Repair of components can only be performed by specially trained and qualified

maintenance personnel with special highly-accurate tools, including costly ones.

• When taking the service life and cost of the instruments into consideration, the

replacement of assemblies offers the user the possibility to use YOKOGAWA instruments

more effectively and economically with a minimum in downtime.
