Servicing

This chapter explains how to replace the Model 146

i

subassemblies. It

assumes that a subassembly has been identified as defective and needs to be
replaced.

For fault location information refer to the “Preventive Maintenance”
chapter and the “Troubleshooting” chapter in this manual.

The service mode in the “Operation” chapter also includes parameters and
functions that are useful when making adjustments or diagnosing problems.

For additional service assistance, see

“Service Locations”

at the

end of this chapter.

This chapter includes the following parts information, testing, adjustment,
and calibration procedures, and component replacement procedures:

“Safety Precautions”

“Firmware Updates”

“Replacement Parts List”

“Cable List”

“External Device Connection Components”

“Removing the Measurement Bench and Lowering the Partition Panel”
