Introduction - Fluke PM6685 Service Manual

Standard Parts
Electrical and mechanical replacement parts can be obtained through
your local Fluke organization or representative. However, many of the
standard components can be obtained from other local suppliers. Before
purchasing or ordering replacement parts, check the parts list for part
number, value, tolerance, rating, and description.
If the value of the physical component differs from what is described in
the parts list, you should always replace the part with the same value as
originally mounted.
Standard parts are unmarked or marked with an 'S' in the P column of
the parts lists.
Special Parts
In addition to standard electronic components, the following special
components are used:
7.2 Replacement Parts, Introduction

Introduction

– Components that are manufactured or selected by the manufac -
turer to meet specific performance requirements.
–
Components that are important for the safety of the instrument.
Both types of components may be replaced only by components ob-
tained through your local Fluke organization.
NOTE: Physical size and shape of a component may af -
fect the performance of the instrument, particularly at
high frequencies. Always use direct replacements un -
less it is known that a substitute will not degrade the
performance of the instrument.
These parts are 'Recommended Replacement Parts' and are marked
with an 'R' in the P column of the parts lists.
Components marked with a 'P' in the P column are 'Production items'
not kept in replacement parts stock. These items can be ordered, but the
delivery time is longer than for normal replacement parts.
