E-DWT-H will automatically test for stability,
and indicate to the operator when it is safe to
take data. Press [ENT] to collect a data point
Try collecting a data point while the
pressure is still unstable and you
have not yet seen the stability light
illuminate green – to see and prove
the unit's reaction to a technician
trying to ignore or override the
stability test.
The stability ready/not ready limit is
equal to 10% of the DUT tolerance.
To collect test data, simply select [ENT].
E-DWT-H will either respond with a tone to
indicate that the DUT measurement at that point
is in tolerance, or a lower tone and OT
indication on the display to indicate that the
DUT measurement is out of tolerance.
When the test is complete, use [SETUP],
<5ATest>, to view the stored test results.
Performance and Safety Features to Note
•
Note that in the E-DWT-H design, special
attention was given to making a system that
minimize vessel expansion and thermal effects
that can cause the system to require a long time
to reach stability. As such, an operator should
be able to set stable test points in about 30
seconds, or no more than 1 minute depending
on the DUT tolerance.
•
The system of lights and audible warnings on
E-DWT-H is intended to keep operators from
applying a high pressure to RPM4-E-DWT while
the Lo Q-RPT is selected. The green lights near
the Lo Q-RPT shutoff valve indicate the position
that the valve should be in based on the current
RPM4-E-DWT selection.

•
There is a relief valve built into E-DWT-H that
protects the Lo Q-RPT in the event that the
operator mistakenly applies a high pressure to
the Lo Q-RPT circuit.
.
•
In addition to audible warnings upon near-
overpressure of a Q-RPT; if the Lo Q-RPT shutoff
valve is set to Lo and the Hi Q-RPT is selected
on the RPM4-E-DWT, an audible warning
sounds if over 300 psi is sensed because it is
likely that the operator has forgotten to change
one of the settings and is applying pressure to
the Lo Q-RPT without the ability to see the
measured pressure.
