ABOUT THIS MANUAL

This manual is intended to provide the user with the basic information necessary to operate an

E-DWT-10000-AF electronic deadweight tester (Portable Hydraulic Gauge Calibrator). It also includes a

great deal of additional information provided to allow you to optimize the use of the instrument and take

full advantage of its many features and functions.

Before using the manual, take a moment to familiarize yourself with the Table of Contents structure: Sections

1.1, 2 and 3. Section 4 is for remote communication with the RPM4-E-DWT from an external computer.

Section 5 provides maintenance and calibration information. Section 6 is a quick troubleshooting guide. Use it

to troubleshoot unexpected E-DWT behavior based on the symptom of that behavior.

For those of you who “don’t read manuals”, go directly to Section 2.3 to set up your E-DWT and then go

to Section 3.1.4 for a typical test procedure. This will get you up and running quickly with a minimal risk of

causing damage to yourself or your new instrument. THEN… when you have questions or start to wonder

about all the great features you might be missing, get into the manual!

Manual Conventions

(CAUTION) is used in throughout the manual to identify user warnings and cautions.

(NOTE) is used throughout the manual to identify operating and applications advice and additional

explanations.

[ ] indicates direct function keys (e.g., [RANGE]).

< > indicates RPM4-E-DWT screen displays (e.g., <1yes>).
