This manual contains information and warnings that must be followed to
ensure safe operation and keep the instrument in safe condition.

Introduction

The Fluke 2635A Hydra Series II Data Bucket is a 21-channel data logging instrument
that measures and records the following electrical and physical parameters: dc volts, ac
volts, resistance, frequency, and temperature. Temperature measurements are via
thermocouples or resistance-temperature detectors (RTDs). Other parameters can be
measured with an appropriate transducer, such as air pressure/vacuum (using a Fluke
PV350 transducer module) or DC current (using a Fluke 2600A-101 shunt resistor).
When the instrument scans channels configured for measurement, readings can be
displayed, printed out, and recorded. Virtually any analog input may be applied without
external signal conditioning. The inputs for channels 1 through 20 are via a Universal
Input Module, which plugs into the rear of the unit for a quick connect/disconnect
capability. Channel 0 measurements are via the front panel input jacks using test leads
(supplied). For a quick introduction to the operation of the instrument, complete the Ten-
Minute Tour at the front of this manual. A summary of the Hydra Series II Data Bucket
features is provided in Table 1-1 and complete specifications in Appendix A. Figure 1-1
shows the instrument front and rear panels.
