2.4.1.2 Configuration Using Custom Table
If none of the nine
Vessel Types
shown can be used, a
Custom
Table
can be created. A maximum of 30 points can be used to
establish the level to volume relationship. The following table
provides an explanation of each of the System Configuration
parameters for volume applications where a Custom Table is
needed.
Configuration Parameter
Explanation (Custom Volumetric Table)
Volume Units
A selection of
Gallons
(factory default Volume Unit),
Milliliters, Liters, Cubic
Feet,
or
Cubic Inches,
is provided.
Vessel Type
Select
Custom Table
if none of the nine
Vessel Types
can be used.
Cust Table Type
The
Custom Table
points can be a
Linear
(straight line between adjacent points)
or
Spline
(can be a curved line between points) relationship. See below drawing
for more information.
Cust Table Vals
A maximum of 30 points can be used in building the
Custom Table
. Each pair of
values will have a level (height) in the units chosen in the
Level Units
screen, and
the associated volume for that level point. The values must be monotonic, i.e.
each pair of values must be greater than the previous level/volume pair. The last
pair of values should have the highest level value and volume value associated
with the level in the vessel.

SPLINE

Point
Use where walls are not perpendicular to base.
Concentrate at least two points at the beginning (P1) and
end (P9); and three point s at either side of transition points

2.4.2 Reset Function
A parameter labeled “Reset Parameter” is located at the end of
the DEVICE SETUP/ADVANCED CONFIG menu. In the
event a user gets confused during configuration or advanced
troubleshooting, this parameter gives the user the ability to reset
the Model JM4 transmitter configuration.
Unique to the Model JM4 transmitter is the ability for Orion In-
struments to fully “pre-configure” devices to customer requests.
For that reason, the Reset function will return the device back to
the state at which it left the factory.
It is recommended that Orion Instruments Technical Support
be contacted as the Advanced User password will be required for
this reset.
2.4.3 Additional Diagnostic/Troubleshooting Capabilities
2.4.3.1 Event History
As a means for improved troubleshooting capability, a record of
significant diagnostic events is stored with time and date stamps.
A real time on board clock (which must be set by the operator),
will maintain the current time.
2.4.3.2 Context-sensitive Help
Descriptive information relevant to the highlighted parameter in
the menu will be accessible via the local display and remote host
interfaces. This will most often be a parameter-related screen, but
could also be information about menus, actions (for example,
Loop [Analog Output] Test, resets of various types), diagnostic
indicators, etc.
For example: Dielectric Range — Selects the range bounding
the dielectric constant of the medium in vessel. For interface
measurement mode, it selects the range bounding the dielectric
constant of the lower liquid medium. Some ranges may not be
selectable depending on the probe model.
2.4.3.3 Trend Data
Another new feature to the Model JM4 is the ability to log
several measured values (selectable from any of the primary, sec-
ondary, or supplemental measured values) at a configurable rate
(for example, once every five minutes) for a period ranging from
several hours to a number of days (depending on the configured
sample rate and number of values to be recorded). The data will
be stored in nonvolatile memory in the transmitter with date
and time information for subsequent retrieval and visualization
using the associated Model JM4 DTM.
