WFM 601 - Service Manual
Preface
This manual provides servicing information for the WFM601 Serial Digital
Compnent Monitor. Material found in this volume is targeted at the service
technician; additional operating information can be found in that instrument’s
“User” manual.
To date there are two manuals available for this instrument. This Service
Manual and a User manual.
Service Level Supported
This manual supports both Module Level (for module
exchange) and Component Level servicing. Module Level servicing utilizes the
block diagram and its descriptions to isolate a problem to the circuits on a
particular etched circuit board. To support Component Level servicing there is
additional theory of operation, schematic diagrams and circuit board parts
locating illustration and cross reference indexes (part location charts) for each
circuit board.
When contemplating the level of servicing that is appropriate for a specific
facility, please consider the fact that this instrument contains etched circuit
boards that utilize surface mount technology. Surface mounted components are
not soldered to the circuit board in the traditional manner, they require special
techniques and tools to remove and re-install.
Specific Content
Much of the information in this manual is shared with the User
manual; however, the depth of the material depends on the potential use. A
quick comparison will reveal that there are installation instructions in both
manuals, along with specifications, servicing, and operating instructions.
The installation instructions in both manuals are nearly identical. Installation of
this instrument is so straight forward that anyone can install the instrument in its
operating environment.
The operating instructions in the User manual are much more detailed than those
in the Service manual. The need for a service technician is considerably less
than that of an end user. If the operating instructions in this manual are not
complete enough, please refer to the User manual for more detailed instructions.
