Users Manual

Getting Started
Provides a quick introduction to instrument setup and operation.
Chapter 1 Introduction
Describes standard features, options, and accessories for the Fluke Hydra Series II Data
Acquisition Unit and Hydra Series II Data Logger. Also, this chapter discusses the
organization and intended uses of this manual.
Chapter 2 Overview
Brings the instrument from its shipping container to operating status. This chapter
provides brief descriptions and a quick walk-through of instrument operation. Read this
chapter to gain a feel for instrument use. But please don’t avoid reading Chapter 3 (for
in-depth operation from the front panel) and Chapter 4 (for computer interface
operation); the instrument is far more powerful than suggested in Chapter 2.
Chapter 3 Operating the Instrument from the Front Panel
Describes all capabilities available through front panel control. The features introduced
in Chapter 2 are described more fully, including descriptions for setting up and using
each type of measurement input (dc volts, thermocouple, etc.) and digital input
(Totalizer, etc.) or output (such as alarms). Other features of the Hydra Series II Data
Acquisition Unit and the Hydra Series II Data Logger are also more fully explained.
Chapter 4 Using the Computer Interface
Describes connecting the instrument to a terminal or host computer and operating the
instrument over the RS-232 Interface. For the Hydra Series II Data Acquisition Unit
only, use of the optional IEEE-488 Interface is also described here. This chapter is
detailed and requires a good knowledge of instrument operation via the front panel (see
Sections 2 and 3).
Chapter 5 Additional Considerations
Provides detailed operating information not provided elsewhere. This chapter also
describes instrument operation for the advanced user. This chapter is written with the
assumption that you have full knowledge of instrument operation from the front panel
(Chapter 3).
Chapter 6 Maintenance
Provides performance tests (suitable as acceptance testing procedures) and routine
maintenance information. Refer to this chapter for explanation of error codes
encountered during instrument operation. Also, this chapter provides parts ordering
information for such commonly used items as fuses, accessories, and publications.
Refer to the "Hydra Series II Service Manual" (P/N 688868) for complete service, repair,
and parts ordering information.
