Important Notice to the User

• This manual contains information for servicing YOKOGAWA’s MV1000 and MV2000.

Check the serial number to confirm that this is the correct service manual for the
instrument to be serviced. Do not use the wrong manual.

• Before any maintenance and servicing, read all safety precautions carefully.
• Only properly trained personnel may carry out the maintenance and servicing

described in this service manual.

• Do not disassemble the instrument or its parts, unless otherwise clearly permitted by

this service manual.

• Do not replace any part or assembly, unless otherwise clearly permitted by this service

manual.

• In principle, Yokogawa Electric Corporation (YOKOGAWA) does not supply parts

other than those listed in the customer maintenance parts list in this service manual
(mainly modules and assemblies). Therefore if an assembly fails, the user should
replace the whole assembly and not components within the assembly (see “Note”). If
the user attempts to repair the instrument by replacing individual components within
the assembly, YOKOGAWA assumes no responsibility for any consequences such as
defects in instrument accuracy, functionality, reliability, or user safety hazards.

• YOKOGAWA does not offer more detailed maintenance and service information than

that contained in this service manual.

• All reasonable efforts have been made to assure the accuracy of the content of

this service manual. However, there may still be errors such as clerical errors or
omissions. YOKOGAWA assumes no responsibility of any kind concerning the
accuracy or contents of this service manual, nor for the consequences of any errors.

or by any means without the express written prior permission of YOKOGAWA. The
contents of this manual are subject to change without notice.

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.
