ABOUT THIS MANUAL

About This Manual

This manual is intended to provide the user with the basic information necessary to operate an E-DWT-H

electronic deadweight tester. 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 provide orientation, start up and operation information. 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-H behavior

based on the symptom of that behavior.

Note

For those of you who “don’t read manuals”, go directly to Section 2.3 to set up

your E-DWT-H 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

WCaution

“Caution” is used in throughout the manual to identify conditions or actions that

could cause harm to the E-DWT-H or to the devices that are connected to the

E-DWT-H.

WWarning

“Warning” is used in throughout the manual to identify actions that could pose a

hazard to the user of the E-DWT-H.

Note

“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>).
