General Information

This Service Guide is the field service reference for troubleshooting, repair, adjustment, and
calibration of the Models 720i, 740i and 750i HFA II - i Field Analyzers, manufactured by
Carl Zeiss Meditec Inc. The information presented in this Guide assumes that the reader is
already trained and experienced in operation and service of the Humphrey Field Analyzer
Series 700.
This field service guide is designed to support Level 1 Field Service, which employs modular
replacement of printed circuit boards and other assemblies that are most effectively repaired
at a central repair facility. This is the service strategy used in U.S. domestic Field Service,
and in Carl Zeiss Meditec Service training classes. See Section 1.3 for additional information
regarding Level 1 and Level 2 Repair Center service.
The procedures in this field service guide assume that the reader is familiar with operation of
the instrument. Complete operating instructions are contained in the HFA II - i
User's Guide. Information contained in the User's Guide is not repeated in this field service
guide. The User's Guide can be ordered separately by standard Carl Zeiss Meditec parts
order. Refer to Section 7 for the User's Guide parts information.
