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!

explanations.

1.1 PRODUCT OVERVIEW
E-DWT-10000-AF is an electronic deadweight tester designed to replace mechanical piston-cylinder
based deadweight testers with a lighter weight, easier to use alternative. The E-DWT is designed to be
used in the lab or instrument shop or to be taken into the field for performing in-situ calibrations and tests.
This high performance hydraulic pressure calibration system combines an electronic reference pressure
monitor and manually operated pressure generation and control hardware in a single, compact and
rugged package. E-DWT offers the ease of use and precision of continuous, real time electronic pressure
measurement with the simple and direct pressure control of high quality manual pressure hardware.
The electronic reference pressure monitor is a special version of DHI’s RPM4, designated RPM4-E-DWT
A70M/A7M-AF. RPM4-E-DWT A70M/A7M-AF covers the range from 0 to 10 000 psi gauge pressure
using two high precision quartz reference pressure transducers (Q-RPTs) and an on-board barometer to
measure pressure.
RPM4-E-DWT A70M/A7M-AF is controlled locally by the operator using its front panel display, keypad
and foot pedal or remotely by a computer using ASCII character command strings over its RS-232
interface.
RPM4-E-DWT A70M/A7M-AF uses an AutoRange feature to automatically select the most appropriate
Q-RPT and to optimize the E-DWT setup to cover the desired range of operation. A half-turn valve
isolates and protects the Lo Q-RPT from high pressure when the Hi Q-RPT is in use. Visual and audible
indicators assist the operator in setting the shut off valve correctly.
The E-DWT includes the hardware necessary to fill the system under test with oil and generate and
precisely adjust pressure across the E-DWT’s 10 000 psi (70 MPa) range.
The E-DWT-10000-AF system is delivered in a rugged, molded plastic transport case and includes two
battery/charger packs.

1.2.3 PRESSURE MEASUREMENT SPECIFICATIONS
1.2.3.1 REFERENCE PRESSURE TRANSDUCERS (RPT)
E-DWT-10000-AF is configured with two quartz reference pressure transducer
(Q-RPT) modules to measure pressure.
The Q-RPTs are intrinsically absolute, operating against a sealed vacuum
reference. Gauge pressure is defined by offsetting atmospheric pressure and
applying dynamic compensation for atmospheric changes using the on-board
barometer (see Section 3.9.1).

3. Predicted Q-RPT measurement stability limit (k=2) over two years assuming regular use of
AutoZero function and short term stability between rezeroing. As stability can only be predicted
and varies from Q-RPT to Q-RPT, stability for a specific Q-RPT should be established from
experience.

4. Maximum deviation of the Q-RPT indication from the true value of applied pressure including
precision, predicted two year stability with rezeroing, temperature effect from 18 to 28 ºC and
calibration uncertainty (assumes calibration reference uncertainty of ±0.02% of reading, k=2),
combined and expanded (k=2) following the ISO “Guide to the Expression of Uncertainty in
Measurement.”.
1.2.3.2 ON-BOARD BAROMETER
The measurement uncertainty of the on-board barometer is not significant to
E-DWT measurement uncertainty. It is used only to measure small, short term
changes in atmospheric pressure to provide dynamic compensation of the
Q-RPT’s atmospheric pressure offset in gauge pressure measurement mode

2.1 UNPACKING AND INSPECTION
2.1.1 REMOVING FROM PACKAGING
E-DWT-10000-AF complete with accessories is delivered in a reusable, molded plastic
shipping container with polyurethane inserts to hold it in place.
Remove the E-DWT-10000-AF and its accessories from the shipping container and remove
each element from its protective plastic bag.
Retain the shipping container for repacking the E-DWT to take it into the field or to ship it
for recalibration or repair.
2.1.2 INSPECTING CONTENTS
Check that all items are present and have no visible damage. If damage is noted, report it to
your Receiving Department for appropriate action.
A new E-DWT-10000-AF includes all items listed in Table 1.

2.2 SITE REQUIREMENTS
Install E-DWT-10000-AF on a flat, stable surface at a convenient height. If using the battery/charger
pack, consider its placement.
When used with its battery/charger pack, E-DWT-10000-AF requires no external support facilities. If not
using the battery, an electrical power source of 100 to 240VAC, 50-60 Hz is required.
2.3 SETUP
2.3.1 PREPARING FOR OPERATION
To prepare E-DWT-10000-AF for check out and operation:
Remove the protective plastic sheet from the front panel display.
Familiarize yourself briefly with the E-DWT front and real panels and controls (see
Section 1.3.1).
Connect the 12 VDC power supply pack to a source of 100 to 240V, 50-60 Hz AC power
and to the 12 VDC connection on the rear of the E-DWT; or, use the battery/charger pack
and cable if battery has been charged (see Section 3.3).
Connecting power causes the RPM4-E-DWT to power up.
Observe the front panel display as the RPM4-E-DWT initializes, error checks and goes to
the MAIN RUN screen (see Section 3.6.1). If the RPM4-E-DWT fails to reach the main
run screen, service is required. Record the sequence of operations and displays
observed and contact a DHI Authorized Service Provider (see Section 1, Table 25).
Check that one of the two green Valve Status LEDs on the front of the E-DWT is lit (the
red LED should NOT be ON). If neither of the green LEDs lights, check that the 12 pin
circular connector on the rear panel of the RPM4-E-DWT itself is properly connected to
the J1 ACC. connector.
Install the four variable volume handles into the variable volume hub on the front of the E-DWT.
Leave the stainless steel plug in the top surface TEST port. Check that the gland holding
the plug is tight.
Check/Set Security Level
RPM4-E-DWT has a security system based on user levels. By default, the security
system is set to “low”, which includes access restriction to internal calibration coefficients,
and there is no password required to change the security level. See Section 3.9.5.5 for
information on the security level system. As part of the RPM4-E-DWT startup, determine
the security level that is appropriate for the RPM4-E-DWT and set a password if desired.
RPM4-E-DWT is delivered with the security level set to “low” to avoid inadvertent altering of
critical internal settings but with access to changing security levels unrestricted. It is recommended
that the low security level be maintained at all times and password protection be implemented if
control over setting of security levels is desired.
2.3.2 SETTING UP AUTOTEST FILES
E-DWT’s RPM4-E-DWT supports automated test/calibration sequences. AutoTest sequence
parameters for testing specific DUTs can be stored in File AutoTest files and recalled to run a
test. Consider setting up File AutoTest files for frequently tested DUTs as part of the E-DWT
set up process (see Section 3.1.3).
