8.1

Introduction

Maintenance is essential for you to use the instrument under the good working condition.
This chapter describes the following tips and notices related to maintenance:

•

Storage of instrument when it will not be used for a long period of time.

•

Notes on repackaging and transportation of the instrument, when the instrument is to be
transported.

•

Performance tests for preventive maintenance and acceptance testings.

If you find anything wrong with functions or operations of the instrument, or if performance test
results do not meet the specifications, contact NF Corporation asking for repair. In doing so,
inform NF Corporation of the outcome of your diagnosis and/or of the performance test results, so
that the company could more quickly respond to your requests.

8.2 Daily maintenance

When you find the surface of the instrument panel or cabinet to be dirty, wipe it with a soft cloth.
When it is extremely dirty, apply neutral detergent to the cloth, wring the cloth firmly and use it to
wipe the instrument surface. Never use such solvent as thinner or benzine, or chemically treated
towels, to wipe the instrument surface, since the surface treatment might be altered and/or its
painting might be damaged.
